Linux Kernel Multicore Debug

[deans]

I'm using CW for PA 10.3.3 to attach to a running Linux kernel, but only get Core 0. The target has 4 cores.

The target is a custom design & CW files have been added to support it, e.g., I have successfully brought up bareboard debug sessions that attach to all 4 cores. All 4 cores are selected in the debug session (Main / Target settings).

Apparently I had this problem years ago on a P5020, see:Linux Kernel Debugging 

A comment was made to select SMP vs. AMP, but I don't see that as a choice anywhere (and it isn't mentioned in CWPADBGUG). I even verified the ...smp attribute is set to "true" in the .launch file.

What am I missing? Is there something else I can check/set in launch or xml files?

Hello Dean Saridakis,

Please refer to the step by step Linux Kernel debugging document Debugging Linux Kernel with CodeWarrior for PA, especially refer to the section "3.3 Debugging the Kernel after the MMU is Enabled".

Have a great day,

That's what I'm doing -- I only get 1 core when the debug session starts.
