FatFs with nor flash memory MIMXRT1062

yamakatb — Mon, 17 Feb 2020 11:52:57 GMT

Hello,

On my custom board has QSPi flash for which I have to read / write via FatFS file system.

So, I'm trying to combine fsl_flexspi_nor_flash.c with FatFS diskio.c with reference to sdcard_fatfs of "SDK_2.7.0_EVK-MIMXRT1060".

However, I realized that f_mkdir failed, and that these were not enough to update certain pages.

Are there any SDKs or documentation available to help you update a specific page in a sector of Nor Flash memory?

Or tell me if there is another good way.

DRESULT nor_disk_write(uint8_t physicalDrive, const uint8_t *buffer, uint32_t sector, uint8_t count)

{

uint8_t writeCount;

assert(count == 1U);

if (physicalDrive != NORDISK)

{

return RES_PARERR;

}

/* Write according to fatfs sector size */

for(writeCount = 0; writeCount < FF_MAX_SS / nor_Handle.bytesInPageSize; writeCount++)

{

if (Nor_Flash_Page_Program(&nor_Handle, (sector * FF_MAX_SS) + ( nor_Handle.bytesInPageSize * writeCount ), buffer + (nor_Handle.bytesInPageSize * writeCount)) < 0)

{

return RES_ERROR;

}

return RES_OK;

}

Hi ,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
According to your statement, it seems that the application code and file system both resides in the QSPI, in addition, the boot mode is XIP, is it right?
If yes, please place the application to run in the RAM as the littlefs_shell does.
