Hi there I tried running FATFS on an STM32H563ZI for the first time. The ‘media’ will consist of a 4Mbyte NOR FLASH of wind-bond (W25Q32). As a reference, I used the eamples (SD-card) -using LAB project as an example. Could someone please describe the procedures I need to take in order to activat…

You are seeing this error in FF_Format() due to a mismatch between the partition number being passed and the number of partitions detected in FF_PartitionSearch(). You are passing 1 as the partition number, which tells FreeRTOS+FAT to format the second partition (indexing starts from 0). However, F…

Hello once again! I’ve just added the format to my flow: here it is. It can be found here if FF_format() requires a valid pxDisk, which can be done by executing FF_CreateIOManager( &xParameters, &xFFError ) first. Note: all the above code is part of the FF_FlashDiskInit() that i show you before. …

FF_PartitionSearch() is the function responsible for scanning the device and filling xPartitionsFound.iCount (if any partitions exist on disk). But, it seems the flash has not been partitioned yet. Before calling FF_Format() on a fresh erased flash (0xFF everywhere), you must call FF_Partition( p…

after running the FF_Partition(/) :slight_smile: several issues raise: first here is the the updated FF_FlashDiskInit: FF_Disk_t * FF_FlashDiskInit( const char * pcName ) { FF_Error_t xFFError; BaseType_t xPartitionNumber = 0; FF_CreationParameters_t xParameters; FF_Disk_t * pxDisk; xFlashS…

** I posted the code after this replay. ** The chat can only post one image per replay. Lines 73-74 must be set prior to calling FF_Partition(). - Otherwise, we don’t do anything, right? After realizing that the FF_Partition is functioning on a 512-byte sector (0x200), I changed my Flash sector…

It seems like you’re encountering issues while integrating FATFS with NOR flash memory on the STM32H563ZI, particularly when calling FF_CreateIOManager() and FF_Mount(). The error you’re facing is related to FATFS not recognizing the flash as being formatted. Before initializing FATFS, you need to e…

Thanks, Clark. Yes, we ensure that the flash has been erased before beginning the FatFs init. Also, for each flash write, erase the sector first and then write. Read/write/erase operations are tested separately in bit tests, and they perform properly. Thank you for your comments.

Thanks, Karahulx. Yes, the remedy you offered solved the previous problem. Thanks However, we are now facing a new issue and I’m on it…let you know. william
