Good morning,
I have tried to do the exercise 6 from the nrf-connect-sdk-intermediate course, my nRF9160 devKit can connect to nRF Cloud and download the new firmware. When running the program, a few errors appear (even without FOTA update deployed). In addition the downloaded firmware is not "installed" when the device is rebooted.
Im using nRF Connect SDK v2.7.0 and the exercise was taken from the Github repo on the branch v2.9.0-v2.7.0 .
Could you help me to solve this problem ? Here are the logs when starting the program with an update deployed on nRF Cloud
*** Booting My Application v1.0.0-906a6119a65b ***
