I trying to initialize my sd card for a while but it is not going well. It is a 4GB SDHC from samsung. So i'm using the olimex board SAM7-EX256 with the at91sam7x256 mcu on it.
When I send CMD0, I get 0x01; After I send CMD 8 and I also get 0x01. Until here all is ok. Now I have to send ACMD41. So I I begin to send CMD55 and I obtain as response also 0x01. After this I send ACMD41 but I always obtain 0xff. Is it normal?
Can someone provide me the code to initialize it.
Thks a lot
