minimal components for SWD to work

[Peter Kmet]

Hi,

I'm designing custom PCB with nRF52832QFAA chip and after custom PCB population I can't make SWD to get working. In order to eliminate where the issue is I would like to start to populate as few components on PCB as possible in order to make chip alive, then add the rest. My question is, will the bare chip start working (SWD) with just 32MHz crystal and loading caps?

Thank you.

Just making sure, remaining - do you mean caps on DEC1, DEC3, DEC4 ?

Thank you.

Yes, and call caps on VDD_nRF

[Peter Kmet]

I am missing caps C24 and C25. Should SWD still work?

[Nguyen Hoan Hoang]

Those pins are the gpio.  Don't know why you need those caps for.

Thank you, VDD caps made the trick !
