ltib configuration to make the FEC interface work

VincentChou1z — Tue, 01 May 2012 11:19:19 GMT

Hi! Friends,

I tried to use "MIN" profile to build my u-boot, kernel and rootfs and successfully booted the QSB. Unfortunately I could not see any eth0 in my "ifconfig" output. I configure my ltib environment based on the BSP userguide. Could anyone share the way to configure the ltib to make my u-boot and kernel access the FEC interface successfully? I appreciate any suggestion!

All I did was go into "Target System Configuration" and selected "start networking", then went under "Network setup" and made sure interface 0 was enabled, set the IP, etc. and it came up when I booted the kernel.

Could you tell me which profile you used to build this configuration?

Min Profile, I always use that one.

Should I still set up different u-boot environment parameters even though I have configured the IP setting with ltib?

Hi! Randy,

I follow your steps but still can only get LO from ifconfig command. Somehow eth0 always failed even I just enable eth0 for my system configuration. Any place I should look into?

I discovered that my problem originates from that I did not set ethaddr in my u-boot environment and then cause the system does not have a hardware MAC address. Now I have already fixed it. Thanks for the help!

Yes, I forgot about that step. I've had to program an ethernet address in some boards that do not have one...not sure if they all are blank, but I know 1-2 boards I have used I had to program one in. Good job!

Hi! Randy, I observed one strange phenomenon. If I build the freescale gnome release in ltib, I discovered that the eth0 cannot be activated even I set up the ethernet MAC address (ethaddr) within u-boot. However, I could make eth0 work if I set ethaddr within u-boot when I use MIN profile. Any hints on what I do wrong?

Sorry - I never use the gnome profile, always only min profile. Or I start with an Ubuntu image and add to it.

Maybe you forgot a setting in the "Target System Configuration"? Or maybe the gnome profile startup doesn't use the "Target System Configuration" settings?
