We have an embedded system running ont he Raspberry Pi 4 and CM4 modules. We have succesfully implemented mender to manage updates via artifacts.
Our application is apcakged as a debian package which allows us to install the application via our own apt repository or dpkg installation locally. This installation path is used for development purposes only, so it does not cause issues for our deployed devices.
When installating via apt or dpkg this causes the system to brick entierly most of the time (sometimes it succeeds without issue). The installation proceeds succesfully, but once the system is rebooted then we don’t even get any boot outputs/kernel messages. I suspect the issue is similar to the one reported at Raspbian update breaks devices | Mender . I suspect our package installation is causing a partition or boot issue, but I am unsure where to look. Do you have any suggestions at how best to debug this issue? We can mount the SD card on a recovery system is needed.
