# mbed OS SDCard Driver (sd-driver) for FAT32 Filesystem Support Simon Hughes 20170329 Version 1.00 # Executive Summary The purpose of this document is to describe how to use the mbed OS SDCard driver (sd-driver) so applications can read/write data to flash storage cards using the standard POSIX File API programming interface. The sd-driver uses the SDCard SPI-mode of operation which is a subset of possible SDCard functionality. This repository contains the mbed-os SDCard driver for generic SPI SDCard support and other resources, as outlined below: - `SDBlockDevice.h` and `SDBlockDevice.cpp`. This is the SDCard driver module presenting a Block Device API (derived from BlockDevice) to the underlying SDCard. - POSIX File API test cases for testing the FAT32 filesystem on SDCard. - basic.cpp, a basic set of functional test cases. - fopen.cpp, more functional tests reading/writing greater volumes of data to SDCard, for example. - `mbed_app.json` mbed-os application configuration file with SPI pin configurations for the CI shield and overrides for specific targets. This file allows the SPI pins to be specified for the target without having to edit the implementation files. - This README which includes [Summary of POSIX File API Documentation](#summary-posix-api-documentation) including detailed instruction on how to use the FAT filesystem and SDBlockDevice driver. The SDCard driver is maintained in this repository as a component separate from the main mbed OS repository. Hence the 2 repositories (mbed-os and sd-driver) have to be used together to deliver the FAT32 Filesystem/SDCard support. This document explains how to do this. # Introduction ### Overview The scope of this document is to describe how applications use the FAT filesystem and sd-driver components to persistently store data on SDCards. The document is intended to help developers adopt the mbed OS POSIX File API support, and in particular to help explain: - How the software components work together to deliver the storage functionality. - How to work with the sd-driver and mbed OS to build the examples. The example code can easily be copied into your new application code. - How to work with the CI Test Shield, which adds an SDCard slot to those targets that do not have already have one. - How to run the POSIX File API mbed Greentea test cases, which provide further example code of how to use the POSIX File API. Section 1 provides an Executive Summary, describing the purpose of the sd-driver, the supporting software, examples, test cases and documentation. Section 2 provides an an overview of the material covered including descriptions of the major sections. Section 3 provides an overview of the mbed OS filesystem software components, including the inter-relationships between the application, POSIX file API, the standard c-library, the mbed OS filesystem and the SDCard driver (sd-driver). Section 4 describes how to build and run an example application for reading and writing data to an SDCard using the POSIX File API. The example begins by describing the procedure for building and testing on the K64F target. The final sub-sections describe how to use the test shield to add an SDCard slot to any mbed target, and hence enable the persistent storage of data on any supported target. Section 5 describes an example application which uses the raw BlockDevice API to read and write data to the SDCard. Section 6 describes how to build and run the SDCard POSIX File API mbed Greentea test cases. There are a number of functional test cases demonstrating how to use the mbed OS POSIX File API. Section 7 describes the POSIX File API and provides links to useful API documentation web pages. ### Known mbed-os and sd-driver Compatible Versions The following versions of the mbed-os and sd-driver repositories are known to work together: - {mbed-os, sd-driver} = {mbed-os-5.4.0-rc2, sd-driver-0.0.1-mbed-os-5.4.0-rc2}. `K64F`, `NUCLEO_F429ZI` and `UBLOX_EVK_ODIN_W2` fopen and basic filesystem tests working. - {mbed-os, sd-driver} = {mbed-os-5.4.0, sd-driver-0.0.2-mbed-os-5.4.0}. `K64F`, `NUCLEO_F429ZI` and `UBLOX_EVK_ODIN_W2` fopen and basic filesystem tests working. - {mbed-os, sd-driver} = {mbed-os-5.4.1, sd-driver-0.0.3-mbed-os-5.4.1}. To find the latest compatible versions, use the following command to see the messages attached to the tags in the sd-driver repository: ex_app7/$ cd sd-driver ex_app7/sd-driver$ git tag -n sd-driver-0.0.1-mbed-os-5.3.4 Version compatible with mbed-os-5.3.4, and private_mbedos_filesystems-0.0.1-mbed-os-5.3.4. sd-driver-0.0.2-mbed-os-5.4.0 Updated README.md to include worked exmaples and restructuring of information. sd-driver-0.0.3-mbed-os-5.4.1 Version compatible with mbed-os-5.4.1. ### Known Issues With This Document There are no known issues with this document. # Overview of mbed OS Filesystem Software Component Stack ------------------------ | | | Application | // This application uses the POSIX File API | | // to read/write data to persistent storage backends. ------------------------ ------------------------ // POSIX File API (ISO). ------------------------ | | | libc | // The standard c library implementation | | // e.g. newlib. ------------------------ ------------------------ // sys_xxx equivalent API. ------------------------ | | | mbed_retarget.cpp | // Target specific mapping layer. | | ------------------------ ------------------------ // Filesystem Upper Edge API. ------------------------ | | | File System | // File system wrappers and implementation. | | ------------------------ ------------------------ // FS Lower Edge API (Block Store Interface). ------------------------ | Block API | | Device Driver | // The SDCard driver, for example. | e.g. sd-driver | ------------------------ ------------------------ // SPI.h interface. ------------------------ | | | SPI | // SPI subsystem (C++ classes and C-HAL implementation). | | ------------------------ Figure 1. mbedOS generic architecture of filesystem software stack. The figure above shows the mbed OS software component stack used for data storage on SDCard: - At the top level is the application component which uses the standard POSIX File API to read and write application data to persistent storage. - The newlib standard library (libc) stdio.h interface (POSIX File API) implementation is used as it's optimised for resource limited embedded systems. - mbed_retarget.cpp implements the libc back-end file OS handlers and maps them to the FileSystem. - The File System code (hosted in mbed-os) is composed of 2 parts: - The mbed OS file system wrapper classes (e.g. FileSystem, File, FileBase classes) which are used to present a consistent API to the retarget module for different (third-party) file system implementations. - The FAT filesystem implementation code. The [FATFS: Generic FAT File System Module](http://elm-chan.org/fsw/ff/00index_e.html) (ChanFS) has been integrated within mbed-os. - The Block API Device Driver. The SDCard driver is an example of a persistent storage driver. It's maintained as a separate component from the mbed OS repository (in this repository). - The SPI module provides the mbed OS generic SPI API. This functionality is maintained in mbed OS. # SDCard POSIX File API Example App for Reading/Writing Data ### Overview This section describes how to build and run an example application that uses the POSIX File API to read and write data to SDCard. The discussion begins by descibing how to run the example on the FRDM K64F target, but this is later generalised to all target platforms that have the standard Arduino form factor headers. Tthe Continuous Integration (CI) Test Shield can be inserted into the headers to add a SDCard slot to the target. The example code is a modified version of the [mbed-os-example-fat-filesystem](https://github.com/ARMmbed/mbed-os-example-fat-filesystem) example modified for use with the sd-driver. The following sub-sections describe the steps for building and running the example: - The [Pre-Requisites](#pre-requisites) section describes the development environment used for this example. Other similar development environments can be used. - The [Create the Example Project](#create-the-example-project) section describes how the application project is created by including the mbed-os and sd-driver code. - The [Build the Example Project](#build-the-example-project) section describes how to build the example application. - The [Insert SDCard into K64F](#insert-sdcard-into-k64f) section describes how to select a card and insert it into the SDCard slot on the K64F. - The [Run the Example Binary on the K64F](#run-the-example-binary-on-the-k64f) section describes how to run the example binary on the target and verify the example has run correctly. - The [Testing with an SDCard on Target XYZ](#testing-with-an-sdcard-on-target-xyx) section describes the use of Continuous Integration Test Shield, which hosts an SDCard slot. By inserting the CI test shield into the Arduino headers of an mbed target platform, the SDCard/FAT Filesystem components can be used to store data persistently on any standard mbed target development board. ### <a name="pre-requisites"></a> Pre-Requisites To work through this example, you should have a working development environment on your machine. For example, the following tools should be installed: - A compiler e.g. arm-none-eabi-gcc. - Python 2.7.9 or later. - [mbed Greentea](https://github.com/armmbed/greentea), the mbed OS test tool. - Git Bash or a similar git command line tool to interact with the ARM mbed GitHub repositories. - [mbed-cli](https://github.com/armmbed/mbed-cli), the tool used to make mbed OS application and test builds. For more information on how to setup a development environment, please review the documentation on the [mbed documentation site](https://docs.mbed.com). ### <a name="create-the-example-project"></a> Create the Example Project First create the top level application directory sd_ex1 and move into it: simhug01@E107851:/d/demo_area$ mkdir sd_ex1 simhug01@E107851:/d/demo_area$ cd sd_ex1 simhug01@E107851:/d/demo_area/sd_ex1$ Next, perform the "mbed new" operation to download the mbed-os repository into this directory: simhug01@E107851:/d/demo_area/sd_ex1$ mbed new . [mbed] Creating new program "ex_sdcard" (git) [mbed] Adding library "mbed-os" from "https://github.com/ARMmbed/mbed-os" at branch latest [mbed] Updating reference "mbed-os" -> "https://github.com/ARMmbed/mbed-os/#5faf4b26c5954d15c7c1cccac6498e0c690ad101" warning: LF will be replaced by CRLF in mbed-os.lib. The file will have its original line endings in your working directory. (mx1_venv1) simhug01@E107851:/d/demo_area/sd_ex1$ ls -1 mbed-os mbed-os.lib mbed_settings.py (mx1_venv1) simhug01@E107851:/d/demo_area/sd_ex1$ Next, get add the sd-driver component to the application project: simhug01@E107851:/d/demo_area/sd_ex1$ mbed add sd-driver <trace removed> simhug01@E107851:/d/demo_area/sd_ex1$ Next, copy the example1.cpp file and `mbed_app.json` files from inside the sd-driver directory to the top level sd_ex1 directory: simhug01@E107851:/d/demo_area/sd_ex1$ cp sd-driver/features/TESTS/examples/example1.cpp . simhug01@E107851:/d/demo_area/sd_ex1$ cp sd-driver/config/mbed_app.json . simhug01@E107851:/d/demo_area/sd_ex1$ The `mbed_app.json` file specifies the SPI bus pin configuration for different targets. The file includes a specific configuration of the K64F which is used because the mbed compile command specifies the K64F build target. The `mbed_app.json` file is described in more detail in the [Testing with an SDCard on Target XYZ](#testing-with-an-sdcard-on-target-xyx) section. ### <a name="build-the-example-project"></a> Build the Example Project Next, build the example application: simhug01@E107851:/d/demo_area/sd_ex1$ mbed compile -m K64F -t GCC_ARM 2>&1 | tee build_log.txt #### WARNING: "mbed new ." command and possible mbed-os sd-driver versioning incompatibilities If you experience problems building the example then it may mean the version of the mbed-os repository created with the "mbed new ." command is not compatible with the sd-driver repository version created with "mbed add sd-driver" command. This is because: - The "mbed new ." creates the mbed-os repository at the latest "Release" e.g. `mbed-os-5.4.0`. - The "mbed add sd-driver" command creates the sd-driver repository at the latest version of master i.e. the tip of master. Changes may be present that are not compatible with the latest mbed-os release e.g. in preparation for the next release. This situation can be resolved by checking out compatible versions of the repositories as described in the section [Setting mbed-os/sd-driver Repositories To Compatible Versions](#settting-repos-to-compatible-versions) ### <a name="insert-sdcard-into-k64f"></a> Insert SDCard into K64F The examples and test cases have been run on a K64F with the following pre-formatted microSDHC cards: - Kingston 2GB mircoSDHC card. - Kingston 8GB mircoSDHC card. - SanDisk 16GB mircoSDHC ultra card. If the card requires formatting then the following procedure is known to work: - Insert microSD card into SD adapter in USB stick (or similar) so the microSD card can be insert into windows PC. - Within file explorer, right click/Format on the USB drive. - Select FAT32, 4096 cluster size, Quick Format. - Format the drive. The microSD card should then be ready for use in the K64F. Insert the formatted card into the SDCard slot on the K64F PCB. ### <a name="run-the-example-binary-on-the-k64f"></a> Run the Example Binary on the K64F Once the binary is built, copy the binary from `/d/demo_area/sd_ex1/BUILD/K64F/GCC_ARM/example1.bin` to the K64F. After connecting a serial console and resetting the target, the following trace should be seen: Welcome to the filesystem example. Opening a new file, numbers.txt. done. Writing decimal numbers to a file (20/20) done. Closing file. done. Re-opening file read-only. done. Dumping file to screen. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 EOF. Closing file. done. Opening root directory. done. Printing all filenames: numbers.txt Closeing root directory. done. Filesystem Demo complete. ### <a name="testing-with-an-sdcard-on-target-xyx"></a> Testing with an SDCard on Target XYZ The standard way to test is with the mbed CI Test Shield plugged into the target board. This pin mapping for this configuration is parameterised in the `mbed_app.json` file. The following is an example of the `mbed_app.json` file available in the repository: { "config": { "UART_RX": "D0", "UART_TX": "D1", "DIO_0": "D0", "DIO_1": "D1", "DIO_2": "D2", "DIO_3": "D3", "DIO_4": "D4", "DIO_5": "D5", "DIO_6": "D6", "DIO_7": "D7", "DIO_8": "D8", "DIO_9": "D9", "SPI_CS": "D10", "SPI_MOSI": "D11", "SPI_MISO": "D12", "SPI_CLK": "D13", "I2C_SDA": "D14", "I2C_SCL": "D15", "I2C_TEMP_ADDR":"0x90", "I2C_EEPROM_ADDR":"0xA0", "AIN_0": "A0", "AIN_1": "A1", "AIN_2": "A2", "AIN_3": "A3", "AIN_4": "A4", "AIN_5": "A5", "AOUT" : "A5", "PWM_0": "D3", "PWM_1": "D5", "PWM_2": "D6", "PWM_3": "D9", "DEBUG_MSG": 0, "DEVICE_SPI": 1, "FSFAT_SDCARD_INSTALLED": 1 }, "target_overrides": { "DISCO_F051R8": { "SPI_MOSI": "SPI_MOSI", "SPI_MISO": "SPI_MISO", "SPI_CLK": "SPI_SCK", "SPI_CS": "SPI_CS" }, "K20D50M": { "SPI_MOSI": "PTD2", "SPI_MISO": "PTD3", "SPI_CLK": "PTD1", "SPI_CS": "PTC2" }, "KL22F": { "SPI_MOSI": "PTD6", "SPI_MISO": "PTD7", "SPI_CLK": "PTD5", "SPI_CS": "PTD4" }, "KL25Z": { "SPI_MOSI": "PTD2", "SPI_MISO": "PTD3", "SPI_CLK": "PTD1", "SPI_CS": "PTD0" }, "KL43Z": { "SPI_MOSI": "PTD6", "SPI_MISO": "PTD7", "SPI_CLK": "PTD5", "SPI_CS": "PTD4" }, "KL46Z": { "SPI_MOSI": "PTD6", "SPI_MISO": "PTD7", "SPI_CLK": "PTD5", "SPI_CS": "PTD4" }, "K64F": { "SPI_MOSI": "PTE3", "SPI_MISO": "PTE1", "SPI_CLK": "PTE2", "SPI_CS": "PTE4" }, "K66F": { "SPI_MOSI": "PTE3", "SPI_MISO": "PTE1", "SPI_CLK": "PTE2", "SPI_CS": "PTE4" }, "LPC11U37H_401": { "SPI_MOSI": "SDMOSI", "SPI_MISO": "SDMISO", "SPI_CLK": "SDSCLK", "SPI_CS": "SDSSEL" }, "LPC2368": { "SPI_MOSI": "p11", "SPI_MISO": "p12", "SPI_CLK": "p13", "SPI_CS": "p14" }, "NUCLEO_L031K6": { "SPI_MOSI": "SPI_MOSI", "SPI_MISO": "SPI_MISO", "SPI_CLK": "SPI_SCK", "SPI_CS": "SPI_CS" }, "nRF51822": { "SPI_MOSI": "p12", "SPI_MISO": "p13", "SPI_CLK": "p15", "SPI_CS": "p14" }, "RZ_A1H": { "SPI_MOSI": "P8_5", "SPI_MISO": "P8_6", "SPI_CLK": "P8_3", "SPI_CS": "P8_4" } } } Note the following things about the `mbed_app.json` file: - The `mbed_app.json` file is used to define target specific symbols for the SPI pins connecting the SDCard slot to the target MCU: - "SPI\_CS". This is the Chip Select line. - "SPI\_MOSI". This is the Master Out Slave In data line. - "SPI\_MISO". This is the Master In Slave Out data line. - "SPI\_CLK". This is the serial Clock line. - The default configuration defined in the "config" section is for the standard Arduino header pin mappings for the SPI bus. The "config" section defines a dictionary mapping functional names to target board Arduino header pins: - "SPI\_CS": "D10". This causes the MBED\_CONF\_APP\_SPI\_CS symbol to be defined in mbed\_config.h as D10, which is used in the filesystem test implementation. D10 is defined in the target specific PinNames.h file. - "SPI\_MOSI": "D11". This causes the MBED\_CONF\_APP\_SPI\_MOSI symbol to be defined in mbed\_config.h. - "SPI\_MISO": "D12". This causes the MBED\_CONF\_APP\_SPI\_MISO symbol to be defined in mbed\_config.h. - "SPI\_CLK": "D13". This causes the MBED\_CONF\_APP\_SPI\_CLK symbol to be defined in mbed\_config.h. - The `"target_overrides"` section is used to override the "SPI\_xxx" symbols for specific target boards, which may have an SDCard slot, for example. This is the case for the K64F, where the "SPI\_xxx" are mapped to the pin names for the on-board SDCard. ``` "K64F": { "SPI_MOSI": "PTE3", "SPI_MISO": "PTE1", "SPI_CLK": "PTE2", "SPI_CS": "PTE4" } ``` - Thus, in the absence of any target specific definitions in the `"target_overrides"` section, all boards will default to using the Arduino header configuration. For those platforms with a `"target_overrides"` section then this configuration will be used in preference. - Hence in the case that you want to test a platform with an SDCard inserted into a fitted CI test shield (rather than the on-board SDCard slot) and there is a `"target_overrides"` section present in the `mbed_app.json` file, you must then delete the `"target_overrides"` section before building. This will result in the default configuration being used (suitable for the CI Test Shield). - Note when inserting the v1.0.0 CI Test Shield into the Arduino header of the target platform, the shield pins D0 and D1 should be bent to be parallel to the shield PCB so they are not inserted into the Arduino header. This is because some boards use the same UART on DAPLINK and D0/D1, which means the serial debug channel breaks and hence the mbed greentea test suite will not work correctly. This is mainly on older ST boards and should not be a problem on `K64F`, `NUCLEO_F429ZI` and `UBLOX_EVK_ODIN_W2`. Note also that the v2.0.0 CI Test Shield doesn't suffer from this problem and the pins don't need to be bent. - When inserting the SDCard into the card slot on the CI test shield, make sure the card is fully inserted. On insertion, there should be a small clicking sound when the card registers, and the back edge of the card should protrude no more than ~1mm over the edge of the CI test shield PCB. If the SDCard fails to register, try gently pushing the metal flexible strip in the shape of a spade at the top edge of the SDCard metal slot casing with a pair of tweezers, bending it a little to lower it into the slot casing. This helps with the insertion mechanism. ### Target K64F with CI Test Shield fitted ![alt text](docs/pics/sd_driver_k64_with_ci_test_shield.jpg "unseen title text") **Figure 2. The figure shows the K64F platform with the CI shield fitted.** The above figure shows the K64F with the v1.0.0 CI test shield fitted. Note: - The pins D0/D1 (top right of CI test shield) are bent sideways so as not to insert into the header. - The SDCard is fully inserted into the slot and overhangs the PCB by ~1mm. # SDBlockDevice Example Application The following sample code illustrates how to use the sd-driver Block Device API: #include "mbed.h" #include "SDBlockDevice.h" // Instantiate the SDBlockDevice by specifying the SPI pins connected to the SDCard // socket. The PINS are: // MOSI (Master Out Slave In) // MISO (Master In Slave Out) // SCLK (Serial Clock) // CS (Chip Select) SDBlockDevice sd(p5, p6, p7, p12); // mosi, miso, sclk, cs uint8_t block[512] = "Hello World!\n"; int main() { // call the SDBlockDevice instance initialisation method. sd.init(); // Write some the data block to the device sd.program(block, 0, 512); // read the data block from the device sd.read(block, 0, 512); // print the contents of the block printf("%s", block); // call the SDBlockDevice instance de-initialisation method. sd.deinit(); } # SDCard POSIX File API mbed Greentea Test Cases This section describes how to build and run the POSIX file API test cases. The following steps are covered: - [Create the FAT/SDCard Application Project](#create-fat-sdcard-application-project). This section describes how to git clone the mbed OS and sd-driver repositories containing the code and test cases of interest. - [Build the mbed OS Test Cases](#build-the-mbedos-test-cases). This section describes how to build the mbed OS test cases. - [Insert a microSD Card Into the K64F for Greentea Testing](#greentea-insert-sdcard-into-k64f).This section describes how to format (if required) a microSD card prior to running the tests. - [Run the POSIX File Test Case](#run-the-posix-file-test-cases).This section describes how to run the POSIX file test cases. ### <a name="create-fat-sdcard-application-project"></a> Create the FAT/SDCard Application Project This section describes how to create an application project combining the mbed-os and sd-driver repositories into a single project. In summary the following steps will be covered in this section: - A top level application project directory is created. The directory name is ex_app1. - In the ex_app1 directory, the mbed-os repository is cloned. - In the ex_app1 directory at the same level as the mbed-os directory, the sd-driver repository is cloned. - The `mbed_app.json` file is copied from the `sd-driver/config/mbed_app.json` to the ex_app1 directory. First create the top level application directory ex_app1 and move into it: simhug01@E107851:/d/demo_area$ mkdir ex_app1 simhug01@E107851:/d/demo_area$ pushd ex_app1 Next, get a clone of public mbed OS repository in the following way: simhug01@E107851:/d/demo_area/ex_app1$ git clone git@github.com:/armmbed/mbed-os <trace removed> simhug01@E107851:/d/demo_area/ex_app1$ Next, get a clone of the sd-driver repository: simhug01@E107851:/d/demo_area/ex_app1$ git clone git@github.com:/armmbed/sd-driver <trace removed> simhug01@E107851:/d/demo_area/ex_app1$ Finally, copy the `mbed_app.json` application configuration file from `sd-driver/config/mbed_app.json` to the ex_app1 directory: simhug01@E107851:/d/demo_area/ex_app1$ cp sd-driver/config/mbed_app.json . simhug01@E107851:/d/demo_area/ex_app1$ The `mbed_app.json` file specifies the SPI bus pin configuration for different targets, and is discussed in the [Testing with an SDCard on Target XYZ](#testing-with-an-sdcard-on-target-xyx) section. ### <a name="build-the-mbedos-test-cases"></a> Build the mbed OS Test Cases Build the test cases for the K64F target using the following command: simhug01@E107851:/d/demo_area/ex_app1$ mbed -v test --compile -t GCC_ARM -m K64F --app-config mbed_app.json 2>&1 | tee build_tests_gcc_20161219_1007.txt <trace removed> simhug01@E107851:/d/demo_area/ex_app1$ The build trace is quite extensive but on a successful build you should see the following output at the end of the log: Build successes: * K64F::GCC_ARM::MBED-BUILD * K64F::GCC_ARM::MBED-OS-FEATURES-FEATURE_LWIP-TESTS-MBEDMICRO-NET-CONNECTIVITY <trace removed> * K64F::GCC_ARM::MBED-OS-FEATURES-TESTS-FILESYSTEM-FAT_FILE_SYSTEM * K64F::GCC_ARM::MBED-OS-FEATURES-TESTS-FILESYSTEM-HEAP_BLOCK_DEVICE * K64F::GCC_ARM::MBED-OS-FEATURES-TESTS-FILESYSTEM-UTIL_BLOCK_DEVICE <trace removed> * K64F::GCC_ARM::SD-DRIVER-FEATURES-TESTS-FILESYSTEM-BASIC * K64F::GCC_ARM::SD-DRIVER-FEATURES-TESTS-FILESYSTEM-FOPEN Build skips: * K64F::GCC_ARM::MBED-OS-FEATURES-FEATURE_LWIP-TESTS-MBEDMICRO-NET-TCP_PACKET_PRESSURE <trace removed> Notice the following tests in the sd-driver tree are listed above: - `K64F::GCC_ARM::SD-DRIVER-FEATURES-TESTS-FILESYSTEM-BASIC` - `K64F::GCC_ARM::SD-DRIVER-FEATURES-TESTS-FILESYSTEM-FOPEN` The FAT32/SDCard test cases are at following locations in the source code tree: /d/demo_area/ex_app1/sd-driver/features/TESTS/filesystem/basic/basic.cpp /d/demo_area/ex_app1/sd-driver/features/TESTS/filesystem/fopen/fopen.cpp #### <a name="settting-repos-to-compatible-versions"></a> Setting mbed-os/sd-driver Repositories To Compatible Versions The sd-driver master HEAD and the mbed-os master HEAD should be compatible with one another and therefore no specific tagged versions need to be checked out. However, in the case that you experience problems building, checkout out the compatible tagged version of each repository, as shown below: simhug01@E107851:/d/demo_area/ex_app1$ pushd mbed-os simhug01@E107851:/d/demo_area/ex_app1$ git checkout tags/mbed-os-5.4.0 simhug01@E107851:/d/demo_area/ex_app1$ popd simhug01@E107851:/d/demo_area/ex_app1$ pushd sd-driver simhug01@E107851:/d/demo_area/ex_app1$ git checkout tags/sd-driver-0.0.2-mbed-os-5.4.0 simhug01@E107851:/d/demo_area/ex_app1$ popd In the above: - `mbed-os-5.4.0` should be replaced with the latest mbed-os release tag. - For an mbed-os release tag `mbed-os-x.y.z`, use the equivalent sd-driver tag `sd-driver-a.b.c-mbed-os-x.y.z` where `a.b.c` is the latest version code for the `mbed-os-x.y.z` tag. ### <a name="greentea-insert-sdcard-into-k64f"></a> Insert SDCard into K64F for Greentea Testing See the previous section for [Insert SDCard into K64F](#insert-sdcard-into-k64f) for details. ### <a name="run-the-posix-file-test-cases"></a> Run the POSIX File Test Case To setup for running the test cases, connect the K64F development board to your PC using a suitable USB cable.

Hardware required: - K64F. - CI test shield. - SPI NOR Flash Device wired to Arduino header pins e.g. the Macronix MX25R2035F. The datasheet is available from the [Macronix website](http://www.macronix.com/). - Micro USB cable. Software required: - mbed CLI (with all other dependencies installed). - ARMCC / GCC_ARM / IAR compiler. - mbed greentea. - git account. Github repos to use: - The [mbed OS repository](https://github.com/armmbed/mbed-os) - The [SPI Flash Driver repository](https://github.com/armmbed/spiflash-driver) ## Simple SPIFBlockDevice Example This section describes how to create an application project combining the mbed-os and spiflash-driver repositories into a single project. In summary the following steps will be covered in this section: - A top level application project directory is created. The directory name is ex_app2. - In the ex_app2 directory, the mbed-os repository is cloned. - In the ex_app2 directory at the same level as the mbed-os directory, the spiflash-driver repository is cloned. First create the top level application directory ex_app2 and move into it: simhug01@E107851:/d/demo_area$ mkdir ex_app2 simhug01@E107851:/d/demo_area$ pushd ex_app2 Next, get a clone of public mbed OS repository in the following way: simhug01@E107851:/d/demo_area/ex_app2$ git clone git@github.com:/armmbed/mbed-os <trace removed> simhug01@E107851:/d/demo_area/ex_app2$ Next, get a clone of the spiflash-driver repository: simhug01@E107851:/d/demo_area/ex_app2$ git clone git@github.com:/armmbed/spiflash-driver <trace removed> simhug01@E107851:/d/demo_area/ex_app2$ In the top level directory create the example2.cpp: simhug01@E107851:/d/demo_area/ex_app2$ touch example2.cpp Copy the [spiflash-driver example code](https://github.com/armmbed/spiflash-driver) and paste into example2.cpp (reproduced here for convenience and corrected to build for GCC_ARM): // Here's an example using the MX25R SPI flash device on the K82F #include "mbed.h" #include "SPIFBlockDevice.h" /* This is the original configuration of the SPI Flash Driver * pins for Freescale K82F development board. We're not using * this as we're using the CI Test Shield */ // Create flash device on SPI bus with PTE5 as chip select //SPIFBlockDevice spif(PTE2, PTE4, PTE1, PTE5); /* This configuration of the SPI Flash Driver pins is for * the Freescale K64F connecting the SPI pins on the * Arduino header to the SPI NOR part. */ SPIFBlockDevice spif(D11, D12, D13, D10); int main() { printf("spif test\n"); // Initialize the SPI flash device and print the memory layout spif.init(); printf("spif size: %llu\n", spif.size()); printf("spif read size: %llu\n", spif.get_read_size()); printf("spif program size: %llu\n", spif.get_program_size()); printf("spif erase size: %llu\n", spif.get_erase_size()); // Write "Hello World!" to the first block char *buffer = (char*) malloc(spif.get_erase_size()); sprintf(buffer, "Hello World!\n"); spif.erase(0, spif.get_erase_size()); spif.program(buffer, 0, spif.get_erase_size()); // Read back what was stored spif.read(buffer, 0, spif.get_erase_size()); printf("%s", buffer); // Deinitialize the device spif.deinit(); } Note the following modifications to the original code sample: - The SPI Flash Driver instance `spif` is given the pin configuration for the SPI bus from the Arduino header pins D11, D12, D13 and D10, as noted in the comments. - The buffer type has been modified to char* to (see line with malloc() above). The application can be built with the following command: simhug01@E107851:/d/demo_area/ex_app2$ mbed compile -m K64F -t GCC_ARM 2>&1 | tee build_app_ex_app2_log.txt Once the binary is built, copy the binary from `/d/demo_area/ex_app2/BUILD/K64F/GCC_ARM/example2.bin` to the K64F. After connecting a serial console and resetting the target, the following trace should be seen: spif test spif size: 2097152 spif read size: 1 spif program size: 1 spif erase size: 4096 Hello World! ## Build the mbed OS Test Cases If you have completed the previous section "Simple SPIFBlockDevice Example" then first prepare the environment by removing the BUILD directory and hiding or removing the example2.cpp: simhug01@E107851:/d/demo_area/ex_app2$ rm -fR BUILD simhug01@E107851:/d/demo_area/ex_app2$ cp example2.cpp example2_cpp Build the test cases for the K64F target using the following command: simhug01@E107851:/d/demo_area/ex_app2$ mbed -v test --compile -t GCC_ARM -m K64F 2>&1 | tee build_tests_gcc_20170322_1007.txt <trace removed> simhug01@E107851:/d/demo_area/ex_app2$ The build trace is quite extensive but on a successful build you should see the following output at the end of the log: Build successes: * K64F::GCC_ARM::MBED-BUILD * K64F::GCC_ARM::MBED-OS-FEATURES-FEATURE_LWIP-TESTS-MBEDMICRO-NET-CONNECTIVITY <trace removed> * K64F::GCC_ARM::MBED-OS-FEATURES-TESTS-FILESYSTEM-FAT_FILE_SYSTEM * K64F::GCC_ARM::MBED-OS-FEATURES-TESTS-FILESYSTEM-HEAP_BLOCK_DEVICE * K64F::GCC_ARM::MBED-OS-FEATURES-TESTS-FILESYSTEM-UTIL_BLOCK_DEVICE <trace removed> * K64F::GCC_ARM::MBED-OS-TESTS-STORAGE_ABSTRACTION-BASICAPI * K64F::GCC_ARM::SPIFLASH-DRIVER-TESTS-BLOCK_DEVICE-SPIF Build skips: * K64F::GCC_ARM::MBED-OS-FEATURES-FEATURE_LWIP-TESTS-MBEDMICRO-NET-TCP_PACKET_PRESSURE <trace removed> Notice the following test in the spiflash-driver tree listed above: - `K64F::GCC_ARM::SPIFLASH-DRIVER-TESTS-BLOCK_DEVICE-SPIF` The SPIFBlockDevice test case is at following locations in the source code tree: /d/demo_area/ex_app2/spiflash-driver/TESTS/block_device/spif/main.cpp This provides an example of reading and writing data blocks to the block device interface for the SPI NOR part.

Software required: - mbed CLI (with all other dependencies installed). - ARMCC / GCC / IAR compiler. - mbed greentea. - git account. Github repos to use: - The [mbed OS repository](https://github.com/armmbed/mbed-os) - The [I2C EEPROM driver repository](https://github.com/ARMmbed/i2ceeprom-driver.git) - The [CI test shield repository](https://github.com/ARMmbed/ci-test-shield.git) for `mbed_app.json` application configuration file. Steps to follow: - Create an empty example project in a suitable directory. Move into it. - Download mbed OS into the example directory via `mbed new .` - Add the I2C EEPROM driver via `mbed add i2ceeprom-driver` - Clone the CI test shield repository to another suitable directory. Copy the mbed_app.json from the CI test shield directory to the top level of the newly created example directory. - Make sure the I2C pins are SDA on D14 and SCL on D15 and the I2C EEPROM slave address is 0xA0 in the mbed_app.json that you just copied. - Connect the target to the host machine. Run `mbed detect` to make sure the target is detected. - Now we are ready to run the greentea tests on this target with `mbed test -t ARM -m K64F -n i2ceeprom-driver-tests-block_device-i2cee -v` - Note that the greentea test above makes use of the main.cpp supplied in the `TESTS\block_device\i2cee` directory. You can customize this if required or use your own test application via main.cpp. Be sure to have only 1 main(). If using a custom main() then you can either have this in the TESTS directory or at the top level example directory. - The tests should pass. If not, time to debug!! - For other targets, please change the target ID string in the test command above to the appropriate one. You can check the supported targets from mbed CLI using `mbed target --supported`.
