Hello

1. On my Chameleon 405EP board, it appears the Ethernet interface is off by default. While the board is running Linux, the Ethernet interface is *not* brought up by default -- rather, I must type 'ifconfig eth0 up'. This seems strange, but I can live with it. While the board is running U-boot, on the other hand, there does not appear to be a 'bring up Ethernet' command. I have MAC address and IP address set in environment variables, so what else do I need to do to get the board to answer a ping???

U-boot will not answer to a remote ping (no interrupt etc). But you can send a ping from U-boot to a remote target if you have CFG_CMD_PING enabled in your configuration.

Did you enable "IP: kernel level autoconfiguration" in your Linux kernel? I use the "bootargs" to give the Linux kernel the appropriate parameters for the eth interfaces. ( setenv bootargs ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname):eth0:off )
