I have a nRF9160 DK (sn 000960004886) that has been working fine, I've tested out to build and load some of the application samples (blinky, hello_world) and they all worked fine.
Then considering the asset_tracker I tried to update the modem firmware (to latest 1.3.1 with the Programmer), and also installed the asset_tracker from your latest application firmware download (2021-12-15) (nrf9160dk_asset_tracker_ltem_2021-12-15_cfedfdfa.hex) and after that my DK does not start (after reset) as normal.
I have log output to terminal, and the log output stops after this log line: "SPM: prepare to jump to Non-Secure image."
After some 150 seconds however, the log output continues: "*** Booting Zephyr OS build v2.7.0-ncs1 ***", and the program continues.
Also the first log output shows this timestamp: "[00:02:30.838,073] ...".
All applications I try to run now have this "feature", a 150sec delay at boot, also those that was running fine before the modem update (e.g. blinky).
Can this be due to the modem not working?
With the at_client program installed and running the LTE Link Monitor that shows only AT command timeouts (e.g. "Error: 'AT ' timed out").
The asset_tracker program also log a lot of errors, see this log output:

Other programs however (e.g. a blinky sample with more logging in the main loop) runs fine, but after the 150 sec "hang" during boot.
Any suggestions on what this startup delay can be, can it be that modem is malfunctioning?
