RAppID Init eTPU config works, eTPU GCT does not

Question asked by Ken Tabacchi on Sep 30, 2016

I used the RAppID Init tool to generate working code for eTPU PWM output channels.

 

Apparently, that tool does not support the other functions of eTPU, PWM input for example, so I switched to using the eTPU Graphical Configuration Tool.  I have not gotten it working yet, even the eTPU PWM outputs that I had working with RAppID, are no longer working.

 

Attached are two minimal CW projects and source code to demonstrate my problem.  In both I am setting PCR 80 of a MPC5644A to eTPU output.  

 

- test_eTPU_RAppID.rar is the one that works and uses the RAppID generated code.  It puts a 2 kHz PWM at 80% duty at PCR 80.

- test_eTPU_GCT.rar does not work and uses the GCT generated code.

 

Please help me fix the GCT code to generate PWM outputs.
