TMS570LS3137: TMS570LS3137

Hello,

Our expert for this topic is current out of office and will reply early next week when they are back. Sorry for the delay in response.

Hi Suguresh,

Can you please elaborate the cross trigger and can you please provide some reference screenshots of your issue.

And also refer below thread, here i explained how to generate High resolution PWM waveforms using HET IDE.

When i was working in low frequency to generate 39Khz to multiple pins like 10pins its creating problem when its reduce to 2to3 pins its working fine. And for 10pins some time its working too.

I never faced this issue before; can you please provide the following details:

1. Which board you are using, is it a custom board or TI-Specific board?

2. If it is a TI-Specific board then which debugger you are using, on chip debugger or external debugger?

3. What are the N2HET pins you are using while you are facing the issue? 

4. Is it possible to share the simplest project for the issue?

i solved the problem by increasing JTAG Clock thankyou for your support.
