Hello all,

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.

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.

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.

Any help is greatly appreciated.

Regards,
G.Sibi
