Hello,everyone
I want to connect LCP23xx and SD Card with MCI interface but i didn't understand flow of them. Now,I founded library coding in SPI mode only. who has it in MCI bus,please help or give information about flow of operation? when i will write data(i just only single block) what i will do first time? --------------------------------------- now, i think(i don't know,is it true?)
In the first(before set pinsel in arm)
i must send command in CMD line from host to card in Card identification mode? (i don't know how to set register,now i try to coding this step)
thank you everyone (sorry if has wrong english:) )
