I have an old MIPS board with a GT-64120 that I would like to port U-Boot to. I have so far got it to boot from flash, init SDRAM and a serial console and give me a prompt so I can run some commands. I am also able to write flash for saving env vars, etc. To make this really useful however I need to get PCI working and then Ethernet.
I don't see any 64120 driver/init code in the sources so unless I have missed something I guess I am going to have to write some.
I now have a driver that initialises the 64120 and U-Boot sees the bridge and Ethernet card. So far so good! But the Ethernet card can not ping anything on my network.
This is what I see...

My guess is that there is probably still something I did not do in the PCI init code, but I have looked at as many examples as I can find and I can't see anything amiss. Any thoughts on what would case the buffer not to work even though the Ethernet card itself is seen and appears to be detected correctly?
Thanks again! Rich
