| joseph_adamu | 1:dc648c5624b9 | 11 | # Executive Summary |
| joseph_adamu | 1:dc648c5624b9 | 12 | |
| joseph_adamu | 1:dc648c5624b9 | 13 | The purpose of this document is to describe how to use the mbed OS SDCard |
| joseph_adamu | 1:dc648c5624b9 | 14 | driver (sd-driver) so applications can read/write |
| joseph_adamu | 1:dc648c5624b9 | 15 | data to flash storage cards using the standard POSIX File API |
| joseph_adamu | 1:dc648c5624b9 | 16 | programming interface. The sd-driver uses the SDCard SPI-mode of operation |
| joseph_adamu | 1:dc648c5624b9 | 17 | which is a subset of possible SDCard functionality. |
| joseph_adamu | 1:dc648c5624b9 | 18 | |
| joseph_adamu | 1:dc648c5624b9 | 19 | This repository contains the mbed-os SDCard driver for generic SPI |
| joseph_adamu | 1:dc648c5624b9 | 20 | SDCard support and other resources, as outlined below: |
| joseph_adamu | 1:dc648c5624b9 | 21 | |
| joseph_adamu | 1:dc648c5624b9 | 22 | - `SDBlockDevice.h` and `SDBlockDevice.cpp`. This is the SDCard driver module presenting |
| joseph_adamu | 1:dc648c5624b9 | 23 | a Block Device API (derived from BlockDevice) to the underlying SDCard. |
| joseph_adamu | 1:dc648c5624b9 | 24 | - POSIX File API test cases for testing the FAT32 filesystem on SDCard. |
| joseph_adamu | 1:dc648c5624b9 | 25 | - basic.cpp, a basic set of functional test cases. |
| joseph_adamu | 1:dc648c5624b9 | 26 | - fopen.cpp, more functional tests reading/writing greater volumes of data to SDCard, for example. |
| joseph_adamu | 1:dc648c5624b9 | 27 | - `mbed_lib.json` mbed-os application configuration file with SPI pin configurations for the CI shield and overrides for specific targets. |
| joseph_adamu | 1:dc648c5624b9 | 28 | This file allows the SPI pins to be specified for the target without having to edit the implementation files. |
| joseph_adamu | 1:dc648c5624b9 | 29 | - This README which includes [Summary of POSIX File API Documentation](#summary-posix-api-documentation) |
| joseph_adamu | 1:dc648c5624b9 | 30 | including detailed instruction on how to use the FAT filesystem and SDBlockDevice driver. |
| joseph_adamu | 1:dc648c5624b9 | 31 | |
| joseph_adamu | 1:dc648c5624b9 | 32 | The SDCard driver is maintained in this repository as a component separate from the main mbed OS repository. |
| joseph_adamu | 1:dc648c5624b9 | 33 | Hence the 2 repositories (mbed-os and sd-driver) have to be used together |
| joseph_adamu | 1:dc648c5624b9 | 34 | to deliver the FAT32 Filesystem/SDCard support. This document explains how to do this. |

| joseph_adamu | 1:dc648c5624b9 | 37 | # Introduction |
| joseph_adamu | 1:dc648c5624b9 | 38 | |
| joseph_adamu | 1:dc648c5624b9 | 39 | ### Overview |
| joseph_adamu | 1:dc648c5624b9 | 40 | |
| joseph_adamu | 1:dc648c5624b9 | 41 | The scope of this document is to describe how applications use the FAT filesystem and sd-driver |
| joseph_adamu | 1:dc648c5624b9 | 42 | components to persistently store data on SDCards. The document is intended to help developers adopt the |
| joseph_adamu | 1:dc648c5624b9 | 43 | mbed OS POSIX File API support, and in particular to help explain: |
| joseph_adamu | 1:dc648c5624b9 | 44 | |
| joseph_adamu | 1:dc648c5624b9 | 45 | - How the software components work together to deliver the storage functionality. |
| joseph_adamu | 1:dc648c5624b9 | 46 | - How to work with the sd-driver and mbed OS to build the examples. The example code can easily |
| joseph_adamu | 1:dc648c5624b9 | 47 | be copied into your new application code. |
| joseph_adamu | 1:dc648c5624b9 | 48 | - How to work with the CI Test Shield, which adds an SDCard slot to those targets that do not have already have one. |
| joseph_adamu | 1:dc648c5624b9 | 49 | - How to run the POSIX File API mbed Greentea test cases, which provide further example code of how to use |
| joseph_adamu | 1:dc648c5624b9 | 50 | the POSIX File API. |
| joseph_adamu | 1:dc648c5624b9 | 51 | |
| joseph_adamu | 1:dc648c5624b9 | 52 | Section 1 provides an Executive Summary, describing the purpose of the sd-driver, the supporting |
| joseph_adamu | 1:dc648c5624b9 | 53 | software, examples, test cases and documentation. |
| joseph_adamu | 1:dc648c5624b9 | 54 | |
| joseph_adamu | 1:dc648c5624b9 | 55 | Section 2 provides an an overview of the material covered including descriptions of the major sections. |
| joseph_adamu | 1:dc648c5624b9 | 56 | |
| joseph_adamu | 1:dc648c5624b9 | 57 | Section 3 provides an overview of the mbed OS filesystem software components, |
| joseph_adamu | 1:dc648c5624b9 | 58 | including the inter-relationships between the application, POSIX file API, the standard c-library, |
| joseph_adamu | 1:dc648c5624b9 | 59 | the mbed OS filesystem and the SDCard driver (sd-driver). |
| joseph_adamu | 1:dc648c5624b9 | 60 | |
| joseph_adamu | 1:dc648c5624b9 | 61 | Section 4 describes how to build and run an example application for reading |
| joseph_adamu | 1:dc648c5624b9 | 62 | and writing data to an SDCard using the POSIX File API. The example begins by describing |
| joseph_adamu | 1:dc648c5624b9 | 63 | the procedure for building and testing on the K64F target. The final sub-sections |
| joseph_adamu | 1:dc648c5624b9 | 64 | describe how to use the test shield to add an SDCard slot to any mbed target, |
| joseph_adamu | 1:dc648c5624b9 | 65 | and hence enable the persistent storage of data on any supported target. |
| joseph_adamu | 1:dc648c5624b9 | 66 | |
| joseph_adamu | 1:dc648c5624b9 | 67 | Section 5 describes an example application which uses the raw |
| joseph_adamu | 1:dc648c5624b9 | 68 | BlockDevice API to read and write data to the SDCard. |
| joseph_adamu | 1:dc648c5624b9 | 69 | |
| joseph_adamu | 1:dc648c5624b9 | 70 | Section 6 describes how to build and run the SDCard POSIX File API mbed Greentea test cases. |
| joseph_adamu | 1:dc648c5624b9 | 71 | There are a number of functional test cases demonstrating how to use the |
| joseph_adamu | 1:dc648c5624b9 | 72 | mbed OS POSIX File API. |
| joseph_adamu | 1:dc648c5624b9 | 73 | |
| joseph_adamu | 1:dc648c5624b9 | 74 | Section 7 describes the POSIX File API and provides links to useful API documentation web pages. |

| joseph_adamu | 1:dc648c5624b9 | 158 | The figure above shows the mbed OS software component stack used for data |
| joseph_adamu | 1:dc648c5624b9 | 159 | storage on SDCard: |
| joseph_adamu | 1:dc648c5624b9 | 160 | |
| joseph_adamu | 1:dc648c5624b9 | 161 | - At the top level is the application component which uses the standard POSIX File API |
| joseph_adamu | 1:dc648c5624b9 | 162 | to read and write application data to persistent storage. |
| joseph_adamu | 1:dc648c5624b9 | 163 | - The newlib standard library (libc) stdio.h interface (POSIX File API) |
| joseph_adamu | 1:dc648c5624b9 | 164 | implementation is used as it's optimised for resource limited embedded systems. |
| joseph_adamu | 1:dc648c5624b9 | 165 | - mbed_retarget.cpp implements the libc back-end file OS handlers and maps them |
| joseph_adamu | 1:dc648c5624b9 | 166 | to the FileSystem. |
| joseph_adamu | 1:dc648c5624b9 | 167 | - The File System code (hosted in mbed-os) is composed of 2 parts: |
| joseph_adamu | 1:dc648c5624b9 | 168 | - The mbed OS file system wrapper classes (e.g. FileSystem, File, FileBase classes) |
| joseph_adamu | 1:dc648c5624b9 | 169 | which are used to present a consistent API to the retarget module for different |
| joseph_adamu | 1:dc648c5624b9 | 170 | (third-party) file system implementations. |
| joseph_adamu | 1:dc648c5624b9 | 171 | - The FAT filesystem implementation code. |
| joseph_adamu | 1:dc648c5624b9 | 172 | The [FATFS: Generic FAT File System Module](http://elm-chan.org/fsw/ff/00index_e.html) |
| joseph_adamu | 1:dc648c5624b9 | 173 | (ChanFS) has been integrated within mbed-os. |
| joseph_adamu | 1:dc648c5624b9 | 174 | - The Block API Device Driver. The SDCard driver is an example of a persistent storage driver. |
| joseph_adamu | 1:dc648c5624b9 | 175 | It's maintained as a separate component from the mbed OS repository (in this repository). |
| joseph_adamu | 1:dc648c5624b9 | 176 | - The SPI module provides the mbed OS generic SPI API. This functionality is maintained in |
| joseph_adamu | 1:dc648c5624b9 | 177 | mbed OS. |

| joseph_adamu | 1:dc648c5624b9 | 311 | |
| joseph_adamu | 1:dc648c5624b9 | 312 | Note the following things about the `mbed_lib.json` file: |
| joseph_adamu | 1:dc648c5624b9 | 313 | |
| joseph_adamu | 1:dc648c5624b9 | 314 | - The `mbed_lib.json` file is used to define target specific symbols for the SPI pins connecting the SDCard slot to the target MCU: |
| joseph_adamu | 1:dc648c5624b9 | 315 | - "SPI\_CS". This is the Chip Select line. |
| joseph_adamu | 1:dc648c5624b9 | 316 | - "SPI\_MOSI". This is the Master Out Slave In data line. |
| joseph_adamu | 1:dc648c5624b9 | 317 | - "SPI\_MISO". This is the Master In Slave Out data line. |
| joseph_adamu | 1:dc648c5624b9 | 318 | - "SPI\_CLK". This is the serial Clock line. |
| joseph_adamu | 1:dc648c5624b9 | 319 | - The default configuration defined in the "config" section is for the standard Arduino header pin mappings for the SPI bus. |
| joseph_adamu | 1:dc648c5624b9 | 320 | The "config" section defines a dictionary mapping functional names to target board Arduino header pins: |
| joseph_adamu | 1:dc648c5624b9 | 321 | - "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. |
| joseph_adamu | 1:dc648c5624b9 | 322 | D10 is defined in the target specific PinNames.h file. |
| joseph_adamu | 1:dc648c5624b9 | 323 | - "SPI\_MOSI": "D11". This causes the MBED\_CONF\_APP\_SPI\_MOSI symbol to be defined in mbed\_config.h. |
| joseph_adamu | 1:dc648c5624b9 | 324 | - "SPI\_MISO": "D12". This causes the MBED\_CONF\_APP\_SPI\_MISO symbol to be defined in mbed\_config.h. |
| joseph_adamu | 1:dc648c5624b9 | 325 | - "SPI\_CLK": "D13". This causes the MBED\_CONF\_APP\_SPI\_CLK symbol to be defined in mbed\_config.h. |
| joseph_adamu | 1:dc648c5624b9 | 326 | - The `"target_overrides"` section is used to override the "SPI\_xxx" symbols for specific target boards, which may have an SDCard slot, for example. |
| joseph_adamu | 1:dc648c5624b9 | 327 | This is the case for the K64F, where the "SPI\_xxx" are mapped to the pin names for the on-board SDCard. |
| joseph_adamu | 1:dc648c5624b9 | 328 | |
| joseph_adamu | 1:dc648c5624b9 | 329 | ``` |
| joseph_adamu | 1:dc648c5624b9 | 330 | "K64F": { |
| joseph_adamu | 1:dc648c5624b9 | 331 | "SPI_MOSI": "PTE3", |
| joseph_adamu | 1:dc648c5624b9 | 332 | "SPI_MISO": "PTE1", |
| joseph_adamu | 1:dc648c5624b9 | 333 | "SPI_CLK": "PTE2", |
| joseph_adamu | 1:dc648c5624b9 | 334 | "SPI_CS": "PTE4" |
| joseph_adamu | 1:dc648c5624b9 | 335 | } |
| joseph_adamu | 1:dc648c5624b9 | 336 | ``` |
| joseph_adamu | 1:dc648c5624b9 | 337 | - Thus, in the absence of any target specific definitions in the `"target_overrides"` section, all boards will default to |
| joseph_adamu | 1:dc648c5624b9 | 338 | using the Arduino header configuration. For those platforms with a `"target_overrides"` section then this configuration |
| joseph_adamu | 1:dc648c5624b9 | 339 | will be used in preference. |
| joseph_adamu | 1:dc648c5624b9 | 340 | - Hence in the case that you want to test a platform with an SDCard inserted into a |
| joseph_adamu | 1:dc648c5624b9 | 341 | fitted CI test shield (rather than the on-board SDCard slot) |
| joseph_adamu | 1:dc648c5624b9 | 342 | and there is a `"target_overrides"` section present in the `mbed_lib.json` file, you must then delete the `"target_overrides"` |
| joseph_adamu | 1:dc648c5624b9 | 343 | section before building. This will result in the default configuration being used (suitable for the CI |
| joseph_adamu | 1:dc648c5624b9 | 344 | Test Shield). |
| joseph_adamu | 1:dc648c5624b9 | 345 | - Note when inserting the v1.0.0 CI Test Shield into the Arduino header of the target platform, the shield pins D0 and |
| joseph_adamu | 1:dc648c5624b9 | 346 | D1 should be bent to be parallel to the shield PCB so they are not inserted into the Arduino header. This is because |
| joseph_adamu | 1:dc648c5624b9 | 347 | some boards use the same UART on DAPLINK and D0/D1, which means the serial debug channel breaks and hence the mbed greentea |
| joseph_adamu | 1:dc648c5624b9 | 348 | test suite will not work correctly. This is mainly on older ST boards and should not be a problem on |
| joseph_adamu | 1:dc648c5624b9 | 349 | `K64F`, `NUCLEO_F429ZI` and `UBLOX_EVK_ODIN_W2`. Note also that the v2.0.0 CI Test Shield doesn't suffer from this |
| joseph_adamu | 1:dc648c5624b9 | 350 | problem and the pins don't need to be bent. |
| joseph_adamu | 1:dc648c5624b9 | 351 | - When inserting the SDCard into the card slot on the CI test shield, make sure the card is fully inserted. |
| joseph_adamu | 1:dc648c5624b9 | 352 | On insertion, there should be a small clicking sound when the card registers, and the back edge of the card |
| joseph_adamu | 1:dc648c5624b9 | 353 | should protrude no more than ~1mm over the edge of the CI test shield PCB. If the SDCard fails to register, |
| joseph_adamu | 1:dc648c5624b9 | 354 | try gently pushing the metal flexible strip in the shape of a spade at the top edge of the SDCard metal slot |
| joseph_adamu | 1:dc648c5624b9 | 355 | casing with a pair of tweezers, bending it a little to lower it into the slot casing. This helps with the |
| joseph_adamu | 1:dc648c5624b9 | 356 | insertion mechanism. |
| joseph_adamu | 1:dc648c5624b9 | 357 | |

| joseph_adamu | 1:dc648c5624b9 | 363 | The above figure shows how to connect the NUCLEO_F429ZI with the v1.0.0 CI test shield. Note: |
| joseph_adamu | 1:dc648c5624b9 | 364 | |
| joseph_adamu | 1:dc648c5624b9 | 365 | - To get the SD Card to work with this platform the CI test shield cannot be connected directly to this board, instead follow the instructions above. |
| joseph_adamu | 1:dc648c5624b9 | 366 | - Any SD-card adapter will work as long as you connect all the relevant pins (MOSI, MISO, SCLK, CS, 3.3V and GND) as illustrated in figure 3. |
| joseph_adamu | 1:dc648c5624b9 | 367 | - The SDCard is fully inserted into the slot and overhangs the PCB by ~1mm. |

| joseph_adamu | 1:dc648c5624b9 | 438 | |
| joseph_adamu | 1:dc648c5624b9 | 439 | This section describes how to create an application project combining the mbed-os and |
| joseph_adamu | 1:dc648c5624b9 | 440 | sd-driver repositories into a single project. |
| joseph_adamu | 1:dc648c5624b9 | 441 | In summary the following steps will be covered in this section: |
| joseph_adamu | 1:dc648c5624b9 | 442 | |
| joseph_adamu | 1:dc648c5624b9 | 443 | - A top level application project directory is created. The directory name is ex_app1. |
| joseph_adamu | 1:dc648c5624b9 | 444 | - In the ex_app1 directory, the mbed-os repository is cloned. |
| joseph_adamu | 1:dc648c5624b9 | 445 | - In the ex_app1 directory at the same level as the mbed-os directory, the sd-driver repository is cloned. |
| joseph_adamu | 1:dc648c5624b9 | 446 | - The `mbed_lib.json` file is copied from the `sd-driver/config/mbed_lib.json` to the ex_app1 directory. |
| joseph_adamu | 1:dc648c5624b9 | 447 | |
| joseph_adamu | 1:dc648c5624b9 | 448 | First create the top level application directory ex_app1 and move into it: |
| joseph_adamu | 1:dc648c5624b9 | 449 | |
| joseph_adamu | 1:dc648c5624b9 | 450 | shell:/d/demo_area$ mkdir ex_app1 |
| joseph_adamu | 1:dc648c5624b9 | 451 | shell:/d/demo_area$ pushd ex_app1 |
| joseph_adamu | 1:dc648c5624b9 | 452 | |
| joseph_adamu | 1:dc648c5624b9 | 453 | Next, get a clone of public mbed OS repository in the following way: |
| joseph_adamu | 1:dc648c5624b9 | 454 | |
| joseph_adamu | 1:dc648c5624b9 | 455 | shell:/d/demo_area/ex_app1$ git clone git@github.com:/armmbed/mbed-os |
| joseph_adamu | 1:dc648c5624b9 | 456 | <trace removed> |
| joseph_adamu | 1:dc648c5624b9 | 457 | shell:/d/demo_area/ex_app1$ |
| joseph_adamu | 1:dc648c5624b9 | 458 | |
| joseph_adamu | 1:dc648c5624b9 | 459 | Next, get a clone of the sd-driver repository: |
| joseph_adamu | 1:dc648c5624b9 | 460 | |
| joseph_adamu | 1:dc648c5624b9 | 461 | shell:/d/demo_area/ex_app1$ git clone git@github.com:/armmbed/sd-driver |

| joseph_adamu | 1:dc648c5624b9 | 464 | |
| joseph_adamu | 1:dc648c5624b9 | 465 | Note: The `mbed_lib.json` file specifies the SPI bus pin configuration for different targets, |
| joseph_adamu | 1:dc648c5624b9 | 466 | and is discussed in the [Testing with an SDCard on Target XYZ](#testing-with-an-sdcard-on-target-xyx) section. |
| joseph_adamu | 1:dc648c5624b9 | 467 | |
| joseph_adamu | 1:dc648c5624b9 | 468 | ### <a name="build-the-mbedos-test-cases"></a> Build the mbed OS Test Cases |
| joseph_adamu | 1:dc648c5624b9 | 469 | |
| joseph_adamu | 1:dc648c5624b9 | 470 | Build the test cases for the K64F target using the following command: |
| joseph_adamu | 1:dc648c5624b9 | 471 | |

| joseph_adamu | 1:dc648c5624b9 | 475 | |
| joseph_adamu | 1:dc648c5624b9 | 476 | The build trace is quite extensive but on a successful build you should see the following output at the end of the log: |

| joseph_adamu | 1:dc648c5624b9 | 508 | |
| joseph_adamu | 1:dc648c5624b9 | 509 | The sd-driver master HEAD and the mbed-os master HEAD should be compatible |
| joseph_adamu | 1:dc648c5624b9 | 510 | with one another and therefore no specific tagged versions need to be checked out. |
| joseph_adamu | 1:dc648c5624b9 | 511 | However, in the case that you experience problems building, checkout out the compatible |
| joseph_adamu | 1:dc648c5624b9 | 512 | tagged version of each repository, as shown below: |
| joseph_adamu | 1:dc648c5624b9 | 513 | |
| joseph_adamu | 1:dc648c5624b9 | 514 | shell:/d/demo_area/ex_app1$ pushd mbed-os |

| joseph_adamu | 1:dc648c5624b9 | 520 | |
| joseph_adamu | 1:dc648c5624b9 | 521 | In the above: |
| joseph_adamu | 1:dc648c5624b9 | 522 | |
| joseph_adamu | 1:dc648c5624b9 | 523 | - `mbed-os-5.4.0` should be replaced with the latest mbed-os release tag. |
| joseph_adamu | 1:dc648c5624b9 | 524 | - 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` |
| joseph_adamu | 1:dc648c5624b9 | 525 | where `a.b.c` is the latest version code for the `mbed-os-x.y.z` tag. |

| joseph_adamu | 1:dc648c5624b9 | 549 | |
| joseph_adamu | 1:dc648c5624b9 | 550 | For example, to run the basic test use: |
| joseph_adamu | 1:dc648c5624b9 | 551 | |
| joseph_adamu | 1:dc648c5624b9 | 552 | shell:/d/demo_area/ex_app1$ mbedgt -VS --test-by-names=sd-driver-tests-filesystem-basic |
| joseph_adamu | 1:dc648c5624b9 | 553 | |
| joseph_adamu | 1:dc648c5624b9 | 554 | To run the fopen test use: |
