I use the Code Composer Studio with AM243x EVM board.
EVM board has uSD slot.
When I use ff_fopen function to open, It is successful to read file pointer.
However, when I use the standard api fopen in the stdio.h, fopen return 0 address.
I guess wrong root makes error code, I don’t know how can I type the drive.
ff_fopen("/sd0/test.txt",“r”) was okay
fopen("/sd0/test.txt",“r”) was failed
anybody know how do I type the drive sign or root.
thank you in advance
