nrf_drv_gpiote_in_init silently fails

[Sergy]

Hi,

I call nrf_drv_gpiote_in_init in multiple places during initialisation to get all peripherals configured. At some point it stops working in the sense that it doesn't produce an error, but I also don't see Configuration created for GPIOTE when I check peripherals status in Keil. What could prevent this function from working properly that I might have done between the calls?

I'm using sdk 12.1 on nrf52832, sd132 v3. 0.0

You mean you the peripheral hardware registers are not altered? From the top of my head I cannot think of anything that would prevent it from configuring the registers. Are you sure it is not stuck in an error loop/reset somewhere? If you add the DEBUG flag in the preprocessor symbols, does it end up in an error loop?

Hi Jorn, Indeed looks like the registers do not get changed. I have a DEBUG flag and it doesnt get stuck in loop, and I can see execution continues (some other tasks are carried out, timers work properly), but the input pin doesnt react as required.

I think it will be necessary to see your code, at least the gpiote_in_init calls before and after it fails, and the code in between the two, as well as the pin numbers of the pins you are using.

Jorn, I created a ticket on the My page. The project is pretty big, so hard to separate the code right now, so I uploaded the whole project, might be easier to find problem as well. Thanks!
