I recently got the Hitex board and I am trying to get the SD peripheral up and running. I have chose not to use the driver the comes with the 4350 because I am using a state based design, and I want to tightly integrate it with a state machine.
I have looked at the code, and set up my initialization accordingly. I get and interrupt for card presence, but I am unable to get a Remote timeout or command done interrupt to fire. I am trying to send the idle command to the card (which I know doesn't respond) but I would expect to get a command done interrupt & I don't.
Is setting up the args register, and setting the START_CMD bit in the CMD register all I have to do to send a command?
Thanks
