mmmh... This time I sent cmd01 255 times using just register r20. I´ll try more than that. I hope it works. By the way i set in SPI control register sck/4.

I tied a 16 Mb mmc card to an atm162 in SPI mode. All working at 2.78 Volts. First I wanted to initialize it so I sent cmd0 and the respond was 0x01. I think it´s ok I mean idle state. Then i repeatedly sent cmd1 however i just got 0x01. No mather how many times i send cmd1 i cannot get 0x00 from the card. Does anyone had this problem before? PD:The mmc card is 16 Mb card from SimpleTech. Yahoo! Groups Links
