Quick Start Asset Tracker v2 on nRF9160DK - Verification Failed

[timov43]

I've tried the following with the Quick Start app v1.2.0, v1.1.0 and v1.0.1.
The log below is from v1.1.0, if I recall correctly. All logs are about same.

Programmed the Asset Tracker v2 without problems but next step, Verification, is failing.

When I open the serial terminal on /dev/ttyACM0 and reset the DK, the following log is printed out:

Any explanation for this?
Something I could do to avoid this problem?

Hello,

*** Booting My Application v2.1.0-dev-4594a8693738 ***

what is this "My Application"? I thought you said you programmed asset tracker.

[timov43]

Hmm...

Well, I suggest you to ask from the person who developed and/or built the asset tracker v2 for the Quick Start application why it claims to be "My Application" and not "Asset Tracker v2".

To be sure that Quick Start app is flashing the correct image, I downloaded the "nrf9160dk_asset_tracker.hex" from here
https://github.com/NordicSemiconductor/pc-nrfconnect-quickstart/blob/v1.2.0/resources/devices/firmware/nrf9160dk_asset_tracker.hex

And then flashed it.

Try flashing the board controller firmware to the nrf52840 chip on the DK. https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf91/nrf9160_external_flash.html#programming_the_board_controller_firmware

Hi, sorry for delayed response.

Even the verification after flashing the Asset Tracker v2 is still failing, the asset tracker v2 app seems to be up and running.
