I don't recognize this code. You use FIL where I expect FILE, f_open where I expect fopen. I've never seen the flag names FA_ERROR, FA_WRITE, and so on. Where does this code come from? That should help me direct you to the correct forum.

Thanks and regards,

ooops .... you are right, I confused this with C2000 forum
this library (f_open, f_read ...) is from fatfs (elm-chan.org/.../00index_e.html)
used in C2000 for read/write in uSD

Hi Mauro,

Are you using TI-RTOS (SYS/BIOS)? If so, which version?

Hi Mauro,

Have you tried the FatFS forums? I recommend that you try there. I think for this type of FatFS specific question, you would get the best help on that forum.
