i'm trying to run the sd/mmc fatfs example coming with ASF for samd21 with no modifications, but the f_open functions always returns FR_NO_FILESYSTEM error. Iformatted the 8gb card FAT32 with windows 10. Im using atmel studio 7.
If i try to introduce the f_mkfs function he error becomes FR_DISK_ ERR.
I do not what to do.
Any hint will be appreciated.
Thank so much.
