Hello Steve,
Thank you for clarifying the #defines - I was also able to use the JTAG interface to load and debug SPL. I was able to force SPL to load uboot from SD Card and step through all the way till "image entry point: 0x8080000".
However, after this step the debugger cannot proceed since I don't have the symbols for uboot loaded. I'm unable to find out how to determine the offset address for uboot after relocation and so I can't step into Uboot and give you more information about where in the code it gets stuck.
Can you please indicate which function gets executed in uboot right at the start - I may be able to add a debug line to see if it even reaches that point? (just a guess)
Thank you for your help. If you need more information from my side - please let me know.
Regards
Santhosh
