Pls give me some working mmc initialization steps;
I tried CMD0 at first and got response 0x01 . But then i give CMD1 but not getting response!=0. Tried in loop untill the response !=0. But not getting response. Tried another MMC .Still same problem. Then i give command(16,0,512,0xfF)//CMD16
But not getting response 1;
Then i had given command(17,0,(512),0xff);//write enable command CMD17
The I could receive 0x05 as response!!!!!!! So i am getting some response as correct. So what is my problem? I think its initialization problem. So any one could give me the correct initialization steps?
