Hi there,
I have a custom board featuring the nRF52840. This is the relevant part of the schematic.
When pressing SW1, the SoC doesn't get reset. Seemingly, it's as if I hadn't pushed the button. Why is that?
Thanks in advance!

Hi
Okay, glad to hear you were able to figure it out. Most likely you thought it's better to have a pull-up too many than too few and added it. I agree that it is not necessary and that your solution should work just fine. For our board files in the device tree, the gpio-as-nreset is indeed enabled by default. I was just thinking if you had made a board file or overlay on your own that this might have been missing.
Let me know if this case can be closed then, or if you have any follow-up questions.
Best regards,
Simon
