Hi,

I was trying with the aws_fota sample, I follow the instruction here and download the app_update.bin with no problem. After it shows completed in 100%, device reboot automatically but wasn’t running the downloaded binary (the version number printed wasn’t changed). I checked the memory using Programmer tool in nRF Connect, seems it have the firmware storage in the memory location. I was new to nrf9160 and fota, can anyone helps me or with any suggestion?

Here is the terminal print:
