Hello all, I am trying to use the DM9000 Ethernet controller on the AU1200. so we connected the DM9000 on the Static bus controller #3 on the au1200. and we configured the RCS#3 as a I/O device. The Physical address of I/O device on au1200 is from the 0xD 0000 0000 to 0xD ffff ffff. I guess I need to convert this address to virtual address for access it. But I don't know exactly how to do it. Do I need to configure the TBL? I am using the YAMON as a bootloader. and try to access the DM9000. But It is not easy for me. Any advice or examples are welcome. Thanks,
