Note
This application doesn't work with the latest updates to mbed OS 5 since USB Device support is currently not available for LPC4088
The purpose of this application is to allow easy manipulation of the QSPI file system from a PC.
The application makes the LPC4088 Display Module appear as a USB Memory Stick when connected to a PC. The PC will see the current content of the QSPI file system plus an image file of the file system that can be downloaded and (at a later time) be used to restore the file system to it's current state.
To use this application:
- Download the lpc4088_displaymodule_fs_aid application using drag-n-drop and then reset the board
- Optionally start a terminal program to read the status messages from the application
- Connect a USB cable to the mini USB slot on the back of the LPC4088 Display Module, and then to the PC
- The PC will install drivers if needed and then the USB Memory Stick will be available as a new drive
- Modify the file system to suit your needs
- With the USB cable still connected, press the USER/ISP/SW1 button on the LPC4088 Display Module
- The application will now:
- disconnect the USB Memory Stick
- write all changes to the QSPI flash memory
- create a new image file of the updated QSPI file system and store it in the .current/ folder
- connect the USB Memory Stick again
- Continue from step 5. until satisfied
Note 1: If the QSPI doesn't have a file system on it or to replace the current one with a new, possibly of a different size, file system just add a file with the name format_qspi_X_mb (where X should be replace with the wanted file system size in Mb). For a 10 Mb file system the file name should be format_qspi_10_mb.
Note 2: The file system that is exposed is a copy (in SDRAM) of the QSPI file system. The reason for this is that the USBMSD class requires a FAT file system.
Note 3: The image files created in step 7.3 above will be a *.fsX file (where the 'X' is the size of the file system in MB so *.fs1 for a 1MByte file system). The *.fsX file extensions are recognized by the HDK and can be used to drag-n-drop to the MBED drive in the same way as the *.bin files are. A *.fsX file will not overwrite the program stored in internal flash.
