RE: Regarding TPU emulation

Sansanka,


I now understand better what your are trying to do.

As you will see in my code, I *conditonnaly* load the TPU code into DTPRAM,
because I think that once in emulation mode, the DPTRAM cannot anymore be
accessed by the PowerPC core, so DTPRAM update becomes impossible, and
otherwise raises a PwoerpC exception...
So I you want to load TPU code as a S19 file you should first apply a hard
reset to the MPC chip.

Could a TPU guru give his advice on this matter ;-)

Objet : RE: [MPC500] Regarding TPU emulation


Hi Jean,
              I have actually tried to download S19 file in debug mode and
then ran the program...I have failed in this process and in between i have
come across memcpy option I thought that is essential so used even that but
still i failed....
  My logic is ....Download the S19 file...in debug mode into RAM..and in
program set RAMBAR to 0xffa0...then set tpu parameters apart from setting
TPU to emulation mode...in this context  I wanna get it clarified should I
set EMU bit after setting priority bit to channel?

             I hope I am succesful in explaing you..Kindly donot mind for
troubling you

bye
