I've attached a copy of my bootlog. I added in one patch to enable
rgmii but that didn't fix it.
(http://ozlabs.org/pipermail/linuxppc-dev/2007-October/043435.html)
I am curious why the new emac driver is enabled in the DENX tree but not
in the upstream trees. Has DENX successfully used this driver on the
Sequoia board? Am I trying something that is known not to work?
I'm interested in helping in whatever way I can. I need ARCH=powerpc to
use the current Xenomai patches, and I need both EMACs so I can evaluate
bonding (for high-availability).
Thanks,
Steve

I have noticed odd behavior on a Sequoia board. Kernel is built from
DENX git, ARCH=powerpc, 2.6.23.1.
Sequence that works:
1) In u-boot, do "dhcp" (this initializes the PHY)
2) Boot linux from flash
3) ifconfig eth0 192.168.0.101 netmask 255.255.255.0 up
Ethernet is now functional, and I can ping the Sequoia (and it can ping
my host)
Sequence that does not work:
1) Boot linux from flash without letting u-boot touch eth0
2) ifconfig eth0 192.168.0.101 netmask 255.255.255.0 up
Ethernet appears to come up, but it is not functional. I.e. I get
"eth0: link is up, 100 FDX, pause enabled" but I cannot ping the board,
and the board cannot ping my host.
Do you have a 100MBit connection? Or Gbit? Could you please send the complete
bootlog.
So, the kernel appears to be missing some initialization that u-boot
provides.
However, eth1 is more strange. U-boot can use it (via "setenv ethact
ppc_4xx_eth1;dhcp"), however, the kernel cannot use it, whether or not
u-boot first initializes it.
If anyone has suggestions on where to look, I'd appreciate it. I'm
going to look at the PHY register settings and see if there are any
clues there...
Again it would be interesting to see the bootlog here.
Best regards,
Stefan
