UBoot hang issue when i enable SerDes protocol selection to 0x00(i.e PCIe1(x4) Configuration in RCW

[nagireddychitta]

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,

Nagi

Hello nagi reddy chitta,

Regarding LS1021 u-boot debugging, please refer to this document U-Boot Debug using CodeWarrior for QorIQ LS series – ARM V7 ISA, it is more useful for you.

For debugging u-boot, no need CW initialization file, the Attach launch configuration is used. The whole u-boot build folder is needed, and you need to import the elf file to CW IDE.

For your problem, I suspect it is caused by the incorrect RCW configuration, would you please provide your RCW file.

Have a great day,
Yiping
