I am getting an fs_close() -5 error (-EIO) when I write to an SD card using fatfs. I determined this error was associated with FR_DISK_ERR in fat_fs.c.
Additional info
- I'm using a custom board.
- I didn't have these problems with NCS 2.5.0
- The contents are actually being written to the card.
- The file closes successfully If I open the file but don't write to it.
