AN5374 eTPU config

William_Klaus — Wed, 20 Mar 2024 19:58:41 GMT

Hello,

I've been trying to run a code example based on AN5374, but I did not succeed. I can't see any outputs on the pwm pins. The master channel pin is not showing any output either. In the document, it wasn't clear when to call the function "etpu_pwmm_master_irq()". My project is attached below, I used the pwmm API from the cw_etpu website.

Am I missing something?

edit: I've tried the recommendations on this other question but it's still not working.

Have you tried to investigate eTPU registers in the debugger?

Do you have properly setup SIU module for used channels?

Indeed, the problem was I haven't configured the SIU. Thank you.
