Hi,
I'm working on a custom made A20 board. I'm able to boot it and everything
seems fine, but I can't get the ethernet to work.
I see the following during boot:
<4>emac_init fetch emac using configuration failed
...
<6>sunxi_emac sunxi_emac.0: eth0: link down
<6>ADDRCONF(NETDEV_UP): eth0: link is not ready
...
When I try:
> ifdown eth0
> ifup eth0
>>> ADDRCONF(NETDEV_UP): eth0: link is not ready
And nothing happens.
Here's my ifconfig output:
eth0 Link encap:Ethernet HWaddr 02:13:04:03:23:20

And here's the relevant part from the fex file:
[emac_para]
emac_used = 1
emac_rxd3 = port:PA00<2><default><default><default>
emac_rxd2 = port:PA01<2><default><default><default>
emac_rxd1 = port:PA02<2><default><default><default>

emac_txd0 = port:PA07<2><default><default><default>
emac_rxclk = port:PA08<2><default><default><default>
emac_rxerr = port:PA09<2><default><default><default>
emac_rxdV = port:PA10<2><default><default><default>
emac_mdc = port:PA11<2><default><default><default>
emac_mdio = port:PA12<2><default><default><default>
emac_txen = port:PA13<2><default><default><default>
emac_txclk = port:PA14<2><default><default><default>
emac_crs = port:PA15<2><default><default><default>
emac_col = port:PA16<2><default><default><default>
emac_reset = port:PA17<1><default><default><default>
Then I decided to give the gmac a try, changed the above with this stuff
<http://www.cubieforums.com/index.php/topic,2676.0/prev_next,prev.html#new>:
[gmac_para]
gmac_used = 1
gmac_rxd3 = port:PA00<5><default><default><default>
gmac_rxd2 = port:PA01<5><default><default><default>
gmac_rxd1 = port:PA02<5><default><default><default>
gmac_rxd0 = port:PA03<5><default><default><default>
gmac_txd3 = port:PA04<5><default><default><default>
gmac_txd2 = port:PA05<5><default><default><default>
gmac_txd1 = port:PA06<5><default><default><default>
gmac_txd0 = port:PA07<5><default><default><default>
gmac_rxclk = port:PA08<5><default><default><default>
gmac_rxerr = port:PA09<5><default><default><default>
gmac_rxdV = port:PA10<5><default><default><default>
gmac_mdc = port:PA11<5><default><default><default>
gmac_mdio = port:PA12<5><default><default><default>
gmac_txen = port:PA13<5><default><default><default>
gmac_txclk = port:PA14<5><default><default><default>
gmac_crs = port:PA15<5><default><default><default>
gmac_col = port:PA16<5><default><default><default>
gmac_reset = port:PA17<1><default><default><default>
Now, I can see the gmac driver is loading, but when I do a ifup/down, I
still get:
> ifdown eth0
> ifup eth0
<6>sunxi_gmac: probed
<6>eth0: PHY ID 00008201 at 1 IRQ 0 (sunxi_gmac-0:01) active
<6>ADDRCONF(NETDEV_UP): eth0: link is not ready
I'm not able to figure out the problem here.
Any help would be appreciated.
Thanks and regards.
