My bsp for u-boot 1.2.0 for AMCC PPC440EPx custom board works. I've moved all bsp code to current u-boot version (1.3.4). All works fine but I am getting program check exception when sending or receiving packet over ethernet (EMAC0). I've tryed to debug it but ethernet works when bdm connected. What was changed in ethernet code for ppc4xx after 1.2.0?

What initialization does your BDM debugger do that your start up code does not do?

I don't know what BDM you are using and am not very familiar with the 4xx family, but Best Practices is to create a minimal BDM config and use that, especially when things work with the BDM plugged in but not when running bare.

If that doesn't help, git bisect.
