I upgraded from an old 2.4.25 kernel to the latest Denx snapshot and cannot get the ethernet to work. I was previously running the FEC driver that used the sdma interface. I get a couple of interrupts and that is it.

Output when initializing:

mpc5xxx_fec_init
fec_priv c3f83160
MPC5200 I2S driver (16 BDs x 16 bytes).
NET4: Linux TCP/IP 1.0 for NET4.0
IP Protocols: ICMP, UDP, TCP
IP: routing cache hash table of 512 buckets, 4Kbytes
TCP: Hash tables configured (established 4096 bind 8192) mpc5xxx_fec_open
mpc5xxx_fec_restart
eth0: duplex set to 1
mii_queue: 600a0000 c0130bb0 00000000 mpc5xxx_fec_interrupt:
mpc5xxx_fec_mii 60080141 c0130bb0 00000000 mii_discover_phy
mii_queue: 600e0000 c0130abc 00000000 mpc5xxx_fec_interrupt:
mpc5xxx_fec_mii 600e0c87 c0130abc 00000000
eth0: Phy @ 0x0, type 88E6060 (0x01410c87)

Whenever I try to transmit anything I get:

mpc5xxx_fec_hard_start_xmit:
dev c3f83000, priv c3f83160, skb c3bcc860

The phy code works in the old fec driver fine, but I have tried the generic phy driver also and it acts exactly the same.

The major change was done by this patch back on Sept 4, 2005:

Modifications to the MPC5200 ATA and FEC drivers based on the linuxppc_2_4_devel-fec+ata.patch and linux.habanero.fifo_cntrl.patch patches from Freescale.

I am running a 5200B. Thanks for any help.

Do you really have the latest snapshot, i. e. top of tree from the git repository?

Best regards,

There are very few personal problems that cannot be solved through  a
suitable application of high explosives.

Yes sir. I have the 2007-7-10 snapshot.

Someone posted what I assume to be a similar problem back in March:

but there was no solution. Thanks for any and all help.
