GPS sample nRF9160 crash at nrf_modem_gnss_start()

[LittleViking]

Hello community...

I was able to compile the GPS sample and flash an actinius icarus (nRF9160) using the Actinius Programmer once and it said successful.

However, the app launches e.g. I can see any print statements from main.c via terminal/screen but then crashes at `nrf_modem_gnss_start()`

github.com/.../main.c

It doesn't even return -1 or anything, instead the app or OS crashes and goes into an infinite loop as follows:

Hi LittleViking,

Actinius Programmer is not our product, Did you nRF9160DK or something else?

Best regards,

[LittleViking]

Yes, sorry for the confusion, the AGPS sample works but the GPS does not work for me. It runs and crashes per the above -- any ideas?

Hi LittleViking,

I tested with nRF9160DK v.1.0.0 + NCS 1.7.0, everything is fine, here is my log. Can you share your hardware and SDK information?

I saw there are differences in the following part, did you do any configuration to SPM?
