TMS320F28P650DK: TMS320F28P650DK: HRPWM of phase shift only works to MEP step 8/9 and then doesn't increase - part 2

Please see below after changing to up-count:

Hi,

Yes both HRDB and HRPHS can work together in up count mode as I mentioned in previous thread.

You can suppress the warnings in up count mode in sysconfig and proceed ahead. Please try and let me know if you have any further questions.

Thanks

Hi,
I converted all the PWMs to up-count, and tested. In one ePWM the HRPHS is still limited to 8/9 count, and in the other HRPHS doesn't work at all. 

Should I prepare another reduced version showing the issue? Anything else I can try?

Cheers, Bryon

How many instances did you enable for up count HR feature and how many work and how many don't work?

Also, which instances don't work? 

Thanks

Hi Prarthan,

I'm preparing a new test program based on EPWM example 13 up-acq that cycles through the same HR steps to test the project.

Can you share the test program that said shows the HRPHS and HRDB working together so I can test it on my launchpad? I will share the results of both these tests.

Cheers, Bryon

Hi,

I had tested this before and it worked in up count mode.

Let me see if I can create one next week, it should be simple enough to just combine the two examples I send in part 1 post.

Thanks

Hi, I modified the project I sent before to up count, and it still doesn't work. Do you need me to send you the project? Cheers, Bryon

Please send I tried at my end and seems to be working fine. 

Thanks
