[U-Boot-Users] Network problem in u-boot.

[André Berggren]

Hi Stefan,

Yes CFG_RX_ETH_BUFFER is defined to 32.

I tried to define INFO_4XX_ENET in 4xx_enet.c and got the following output when the problem occurs.

=> run setup
Trying ppc_4xx_eth0
About preceeding transfer (eth0):
- Sent packet number 10626

We had problem with MAL error in Linux to untill we got a backport of the latest driver to our kernel. After that there is no problem in Linux.

Hi Andre,

OK. One other idea: Do you have CFG_RX_ETH_BUFFER defined in your config file? 
If yes, what is the value? Try increasing it. I would suggest to use at least 
16 rx buffers.

Best regards,
Stefan
