Hello,
I am still trying to set up the TMS570 HSK and I am yet to get the ENDRV to stay high.
The error count in the TPS is constantly at 7 and it is forcing the device to reset making debugging difficult.
I am aware that an error count above 5 causes the ENDRV line to stay low.
This is the code I am trying to use to initialise the TPS and watchdog (taken from the TPSDriver-User'sGuide-v2.2.0.chm)
