I have been debugging further using the UART to send output directly to serial post. Now I see that just after entering start_kernel, a ITLB miss exception occurs and linux hangs at that point. Looks like the kernel is probably not running at all yet, may stuck in early initialization. >> Yes 1.

Not sure on the tools you are using to build it. You mention the EDK, but you must not be using it's compiler as it's not configured in the EDK to build Linux. >> EDK 9.2 version, XMD for debug. Kernel 2.6 version is built in linux >> machine and zImage.elf is downloaded to the board. Thanks for the UART suggestion, works well. Any suggestions as to what might be wrong in start_kernel function ? I will continue debugging meanwhile.
