I'm using U-boot to bring up a custom 440gp-based board. We are able to transfer the kernel image (uImage) to the target board's memory and jump to it. But, the kernel seems to hang after that.
Did you try looking at the logbuffer:

We have verified that the board info struct and the clock frequencies are ok. We also have a BDI2000 hardware debugger with us, but we are unable to set any breakpoints using this (both using telnet or using gdb). However, I can use the telnet interface and single-step the 440gp after it seems to hang. I found that 440gp is infinitely looping through the "DataTLBError" routine.
I assume that you have a linux port for your "custom" board and are *not* using the linux kernel image for some other 440 board, right?
It is unclear to me what might have caused this in the first place. Has anyone seen this behaviour before?
We are currently working on getting breakpoints to work using the BDI2000.
What is BREAKMODE set to in your BDI2000 config file? Try using "HARD".
Best regards, Stefan
