RM48 HDK pmu

Other Parts Discussed in Thread: HALCOGEN

Hi,


I'm using the PMU module of the RM48 on HDK REV - D & E with halcogen.

With Halcogen 04.05.01, in the file sys_pmu.asm the first line of code is missing  for _pmuSetCountEvent_ and _pmuGetEventCount_ function

Yours,

Martin V.

    Martin,
    I can see your screen shot, but I do not understand what you are comparing.
    Within this function, r0 and r1 are not defined because they are expected to be passed as arguments.

    Best Regards,
    Kevin Lavery

    In the thread Errors in setting the Performance Counter Selection Register in HALCoGen 04.03.00? I suggested removing the initial lsr instruction which left-shifts the counter parameter by one bit before writing to the Performance Counter Selection Register, since the instruction meant the _pmuSetCountEvent_  and _pmuGetEventCount_  functions didn't operate as expected.

    With Halcogen 04.05.01 the contents of the sys_pmu.asm file matches my suggested changes in the referenced thread.

    My concern is that my suggested code change has broken some existing applications. Could someone from TI comment.
