Anyone here know how to bit-bash a MicroSD card using its SPI interface?
I have an extra port at address #B004 that I'm using to control CS, DI and CK of the uSD.
I seem to be able to send the CMD0 and get the response 00000001 which indicates in_idle_state. But when I send any other command, say CMD8, the response is 00000101 which is in_idle_state and illegal_command.
I've tried half a dozen different make/model cards.
