I have an application that uses the TMS570LS3137 processor. The HET 1 module is used to produce several PWMs The HET2 module also produces a PWM at a different frequency. The ADCs are triggered by RTI 0 interrupt. I recently changed the main timing loop interrupt. It used to be triggered by RTI 1. Now I am having the HET module trigger the main CPU timing loop by having the HET "CNT" instruction trigger the interrupt; I am no longer using (RTI 1).
This all seems to work, but now I am getting ESM group3 errors during power-up.
Can you give a suggestion what I should look for to fix this error?
