FATFS corruption

[Nandi]

My issue like this ticket

https://devzone.nordicsemi.com/f/nordic-q-a/39428/usb-msc-corruption

I suspect it is caused by a problem in the implementation of the NRF_BLOCK_DEV_QSPI_FLAG_CACHE_WRITEBACK function. Can you help verify it?

Hi,

If the suggestions in the case you link does not help, then we need a way to replicate your specific issue on an nRF5280-DK. Please share a simplified project that we can unzip in the nRF5 SDK, run an nRF52840-DK, and a short description we may follow to recreate the issue.

Best regards,
Kenneth

The issue of the link has not been resolved. For the phenomenon, please refer to the link.

The link refer to multiple firmwares and questions.

So please provide a project I can compile to replicate your specific issue here. You may also try the latest nRF5 SDK v16 for latest features and fixes in general.

I have seen many similar problems on devzone, but Nordic has no solution. If you can, please find a similar ticket to help confirm whether I suspect it is correct. Issue I previously reported
