Hi All,


My Ls1020ATWR custom platform is hanging in UBoot(meaning no console prints)when i enable Serdes Protocol Selection to have PCIe1(X4) configuration in the RCW bits SRDS_PRTCL_S1[128-138].


As i do not any prints, it will be difficult to debug the issue of hang and hence  i started trying debugging Uboot using CW tool with CodeWarrior TAP as debugger, but got into some confusion while following the AN4876.pdf to create a project with uboot elf image + Initialization file which document is talking about.


I am not sure which initialization file we are suppose to select in the tool for my platform(i.e LS1020A).

I have the required Uboot binary with symbols.


Can someone throw some light here to continue debug in right direction pls?


Best Regards,
