Hi,
I am working on interfacing SD card to mc9s08aw16. I have used CMD0 and CMD1 to initialised the card and have got the required response from the card.
I have a problem to read CSD, CID registers and also to read and write to SD card.
When I send CMD9 to SD card and wait for the 0x00 response first and then wait for 0xFE followed by the 16bytes from CSD. But the SD card only returns 0xFF and nothing else.
When I send CMD17 to SD card, I get the 0x00 command response but I do not receive 0xFE data response.
I have gone through a lot of forums and websites regarding this and none seemed to have helped me.
Can someone help me out on this!
Regards,
Deepak
