FOTA downloading but failing to boot into the new image

[JackFitton]

Hardware: thingy91X

mfw_nrf91x1_2.0.4

ncs-v3.3.0

using the COAP nRF cloud FOTA sample

I have tried to update my device following the dev academy sample. 

I flashed V1.0.0 onto the device, edited the version to V1.1 in VERSION and then ran a pristine build, created a bundle, and set up a FOTA job on nRF cloud, 

the device downloaded the FOTA image and restarted but did not apply the updated image. I have attached the logs below, it is still showing as V1.0.0 on nRF cloud

(These logs are from the initial test with the REST sample however the same issue was seen with COAP sample)

[Hakon]

Hello,

can you show the logs with a few more logging options enabled? First off you can enable CONFIG_MCUBOOT_LOG_LEVEL_INF or even CONFIG_MCUBOOT_LOG_LEVEL_DBG for more explicit logging information.

[JackFitton]

Hello Hakon,

CONFIG_MCUBOOT_LOG_LEVEL_X doesn't compile for me, I instead used CONFIG_MCUBOOT_UTIL_LOG_LEVEL_DBG

logs and prj.conf are below. all is default except the line you asked for at the bottom

it is still booting into " nRF Cloud CoAP FOTA Sample, version: 1.0.0" when V1.1.0 is on nRF cloud

All I changed between them is 

VERSION_MINOR = 1 in VERSION

[Hakon]

Could you share your sysbuild/mcuboot.conf and sysbuild/mcuboot.overlay (or equivalent) so we can verify the MCUboot-side external flash configuration?

[JackFitton]

nrf_cloud_coap_fota.zip

Hi Hakon,

I am doing this with a complketely fresh install of V3.3.0

I cannot see a mcuboot.conf  or sysbuild/mcuboot.overlay in ncs/v3.3.0/nrf/sysbuild

[Achim Kraus]

You may fetch the ".conf" from "build/mcuboot/zephyr" directory along with the "partitions.yml" from "build" directory.

By the way, maybe Nordic has just not retested FOTA for Thingies as in NCS 3.2.3 (see migrating app using mcuboot to NCS 3.2.3 - issue with MCUboot image IDs automatically assigned? ). Then it would be much faster to do that test on Nordic's side instead of trying to gather all the info from the user.

[JackFitton]

I have managed to get some more logs out of the device

nRF cloud is now saying "Complete with Errors" for the download

I have tried both the dfu_mcuboot and dfu_appllication.zips and it gives me the same error with both
