I am following "Snippet 2: PDM/PCM Asynchronous Receive" from the link below:

https://cypresssemiconductorco.github.io/psoc6hal/html/group__group__hal__pdmpcm.html

The pdm_pcm_event_handler never gets called but when I comment out the line below it starts working.

 
Do I need other configuration/code to activate DMA with PDM/PCM?

Hi @naku_4836966 , The issue is identified to be with DMA HAL drivers and it has been fixed in the latest release of HAL (yet to be released). We tested the fix internally and it works.  You could add DMA transfer functionality once this fix has been updated in the HAL drivers in github. We appreciate your patience.
