hi to everyone

 

I'm trying to use the library 21 sd_card demo by stm32f4-discovery.net but I have a problem with the write/read file on sd card. f_mount is okay (set red led) but f_opens failed with code error 0x03 FR_NOT_READ. I tried to debug, but I didn't understand where is the problem. I increased HEAP and STACK from 0x200/0x400 to 0x2000/0x4000 but without any success.

 

where is the problem?

thanks in advance
