TMS570LS3137: Testing of lockstep core

Part Number: TMS570LS3137

Hi Team,

I raised the case (e2e.ti.com/.../658112

We tried to call ccmSelfCheck and wanted to check if CCMSR is updated or not which is not happening.
Also, we tried to manually update CCMKEYR register for error injection, still its not getting updated.

As we are using eval boards, will these work on these boards?

Regards,
M.Sreenivasan.

    Hello Sreenivasan,

    The CCMRx IP will not provide a result when running in debug mode. i.e., when connected to the IDE. See the following note in the TRM with respect to this behavior:

    ..

    The best way to debug and/or test CCMR4F behavior is to use markers in the code such as GPIO toggles or UART messages to a console to document code flow and execution success.
