nRF Cloud FOTA: Doesn't apply application firmware.

[nardoz-dev]

Hi all, I am experiencing some problems related to the installation of the new application firmware downloaded via FOTA.

I started from the nRF Rest Cloud Fota example, the code manages to identify itself on nRFCloud, manages to find the Update job, starts to download the new fw, but when it reboots, it starts again with the same previous code and does not apply the new one.

By searching on this site i follow : ERROR: FOTA download reverted to the previous version nRF9160 , in fact i setting the static partition and futhermore i add boot_write_img_confirmed().

There's the /{CurrentApplicationDir}(configuration/pm_static.yml

Am i missing something ? 

Thanks !!!

Hi,

If you look at the build log, is the pm_static.yml file applied?

I don't think it will get automatically picked up when it is placed in a sub-folder.

Can you try to either move it up to the project directory (i.e. next to the CMakeLists.txt file and prj.conf), or add the following line to your CMakeLists.txt file above the 'find_package(...)' line?

set(PM_STATIC_YML_FILE ${CMAKE_CURRENT_SOURCE_DIR}/configuration/pm_static.yml)

Best regards,

Didrik

Hello,

Thank you, now the new application firmware is loaded correctly.
Kind regards,
