I just realized tha nrfx example covers both cases (DPP/PPI). I'll base my code on that. Thanks!

Ouch... I'm building for a nRF52840 (M4)... I just realized I used this sample originally for nRF5340, (M33), so that would explain the the errors...

Is there any way to go a bit higher level on Zephyr so that the HALs could abstract from PPI/DPPI and run on both platforms?

Hi João

Thanks for sharing your code.

Which board are you trying to build for?

The error you shared looks similar to the error I got when trying to build a DPPI example for a board that doesn't support DPPI (like the nRF52 series).

Best regards
Torbjørn

Wouldn't you need to enable DPPI in your configuration as well?

CONFIG_NRFX_DPPI=y

Why you didn't need this in the earlier version I am not sure, possibly you used some other library which selected the DPPI configuration automatically.
