Hi,
I'm trying to initialise a 2GB Transcend SD card with an AT89C51AC2.
I send CMD0 and get a 0x01 response. It's initialising...
Then I send 10 CMD55 messages and get no valid response (0xFF) each time. I don't know why I don't get a 0x01 response here until the card has finished initialising?
Sound familiar to anyone?
