    We need to use Compact Flash in our application code. We have mapped CPLD to 0x50000000, with compact flash starting at 0x5A000000. Beginning at this address, I can read the CIS info properly by means of a simple routine. However, when sending the Identify Drive command (0xEC), I receive invalid data through data register. Also, DRQ bit in status register, which signals that data is available for reading, never gets set. Any help is greatly appreciated!
