I've tried running l2_e2_sol from Cellular IoT Fundamentals course on nRF9160DK with SDK 3.2.0 but I got:
[00:00:00.502,014] <inf> Lesson2_Exercise2: Initializing modem library [00:00:00.695,983] <err> nrf_modem: Modem has crashed, reason 0x10, PC: 0x114f04 [00:00:00.696,563] <err> nrf_modem: Modem library initialization failed, err -5 [00:00:00.696,563] <err> nrf_modem: Modem library did not initialize: -5 [00:00:00.696,563] <err> modem_antenna: Modem library did not initialize: -5 [00:00:00.696,594] <err> lte_lc: Modem library init error: -5, lte_lc not initialized [00:00:00.696,594] <err> Lesson2_Exercise2: Failed to initialize the modem library, error: -5 [00:00:00.696,594] <err> Lesson2_Exercise2: Failed to configure the modem
My board is more than 2 years old and was unused for that time so I updated modem firmware:
1. I erased board with nrfjprog --recover
2. I used nRF Connect for Desktop 5.2.1 and Programmer to write MFW v1.3.7
3. I rebuild and reflashed l2_e2_sol
It did not help me get rid of the above errors. I am running everything on Linux Mint 22 with 6.14.0-37-generic kernel.
