In general I follow your argument, but as I said this is the defacto standard OS FatFS implementation, not just any hacked FS. If something needs to be considered not thoroughly tested that would be the FreeRTOS-Plus library.

NOTE : FreeRTOS-Plus-FAT is a FreeRTOS Labs project. It is fully functional, and quite mature, but as an originally acquired (rather than authored) product it does not necessarily meet our production code or testing standards.

Sorry for the late reply
Create a folder has been solved

I increased the stack size of the thread 4096->8192
I increased the total heap size 61440->92160

Please tell me how to read files in a folder
Is the following incorrect?

#define FILE_NAME “0:TEST1/ra_sdhi.txt”
file_pointer = ff_fopen ((const char *) FILE_NAME, READ_MODE); → NG
→ file_pointer=NULL

#define FILE_NAME “ra_sdhi.txt”
file_pointer = ff_fopen ((const char *) FILE_NAME, READ_MODE); → OK
