Issue with Fatfs on SLC micro SD with wear leveling

[frnt]

Hello,

I'm using a microSD connected with SPI to a STM32F4 microcontroller. I have used MLC micro SD card with fatfs for years without any issues. Recently, I have switched to SLC NAND micro SD, Industrial grade, with Wear Leveling (for application specific reasons). However, when I try to mount the new SD card I get FR_NO_FILESYSTEM.

Do someone have an idea why it is not working as expected?

If you are using the HAL/Cube code, the answer is clear - because it is a broken bloatware. The solution is obvious - replace it with up to date FatFS and a normal driver and other code, which is not developed by inc0mpetent fools.

Check what content of sector zero / MBR and partition table.

Check if a supported file system, and suitably ffconf.h configuration for support.

Hello @Piranha ,

yes I’m using CubeIDE with the fatfs version provided by ST. The card is formatted in Fat32, allocation unit 4K.

There is an updated version of fatfs that I can import?

I have checked the ffconf.h file but I don't see any special configuration that can help. I see that the microSD is recognized as SD standard which is different from the older ones that were recognized as SDHC.
