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
