So I enabled the debugging messages on the hacked up ethernet driver. I've
included it at the end, basically this is the Rhine driver with some of the
names changed at the moment. (and some not changed :-)
Some questions, not sure why I get "IDE failed to identify unit 0" but
while its on the list of things to check out and fix, it seems harmless for
now.
The init phase of the ethernet driver finds the MAC as expected matching it
to DID 3065. Sets up the TX and RX buffers and BAR addresses. Does some
D-link specific code (which I'll probably delete if I can't figure out what
it does, remember this is a VIA southbridge, not a D-link card)
It then finds the PHY, hooks the interrupt, and registers the device. So
far so good.
Then it sends a BOOTP request, and promptly gets a BOOTP response
(assigning it address 192.168.110.108. Which for reasons I don't understand
it ignores and trys again.
So that is where I currently am on my journey. Things on the TODO list:
1) Convert the RHINE constants to VT8235 constants and validate
2) Hook up the PHY through the eth_phy API (remove inline code)
3) Optional: Build a simple packet cracker into the debug code
so that redboot can decode some packets.
4) configure my RPM so that I don't have to keep walking over to the
target to power cycle it ;-)
