nrfx_gpiote_irq_handler not called on nRF52832

[Franz]

Hi,

I have a project running on a custom board with the nRF52810 populated and I make use of a GPIOTE input interrupt. The code works fine for the nRF52810, but not when "migrated" to a board containing the nRF52832 (Rev.2). Include paths are the same. I have checked sdk_config.h for enabled modules, checked the startup files(proper ones for nRF52832), the preprocessor settings, project macros, memory settings and all I can think about and the settings seem to be fine for the nRF52832 when i compare them to example projects.

On the nRF52832, the nrfx_gpiote_irq_handler is never called on a edge of the pin (checked with scope)

1.) Do I need to have a softdevice enabled to use the  nrfx_gpiote module? (i don´t think so)

2.) Do you have any hints on how I can narrow down the problem?

Thanks!

Hi, sorry for the late reply. Yes, nrfx_gpiote works without softdevice.

Is the nRF52832 also on a custom board? Are you able to check if the pinout is as expected by toggling the GPIO output? First write directly to the NRF_GPIO->OUT register to see if the wiring/HW is correct. Then use the gpio/gpiote library and see if it behaves the same way.

You can also try to configure the GPIOTE module directly to see if it is a hardware or software issue: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/gpiote.html?cp=3_1_0_20_3_2#register.CONFIG-0

Sorry for the delay from my side. I had a hard time figuring out the problem - in the end it was a damaged pin of the module...
