MPC5744P performance monitor

[billie60]

Hello！

I am trying to set a performance monitor interrupt in MPC5744P. So I want to check registers setting like PMGC register, PMLCa registers, or PMC registers. But I cannot see them in Registers view or EmbSys Registers view. Where can I check them? Can you help me? thanks!

best wishes

Unfortunately, it is not possible to view it with S32DS debugging view.

Apparently the only solution is to use different debugger (for instance Lauterbach TRACE32 is capable to show them) or access to these registers SW way.

There is an appnote for the feature.

An access is indirect with using of mfpmr and mtpmr instructions.
