Our board is based on the Alchemy DBAu1500

We are using a compact flash card that as an IDE drive (tied into the IDE interface of the CPU just like the DBAu1500).

During ide_init, the ATA_STATUS byte is read, and there is a wait loop which waits for the status to be ready. This loop always times out. I am trying to debug this. Tracing through ide_inb, and ide_outb, the address of the interface is fine CFG_PCMCIA_MEM_ADDR (0x20000000). I know that there has to be some TLB mapping between CFG_PCMCIA_MEM_ADDR (0x20000000) and AU1X_SOCK0_IO (F00000000) - I just cannot find where this is done.

Any suggestions?

Thanks
