I am trying to make custom firmware images in the openwrt-imagebuilder-wrapper for the omega2lte. How do I add the build model to the profile?

I was able to successfully make and compile firmware for the omega2 and omega2+ but these firmwares don't work on the omega2lte device. Here are the errors:

root@Omega81A4:/mnt/mmcblk0p1# sysupgrade onion_omega2p-22.03.5-20240717.bin 
Image not in /tmp, copying...
Device omega2lte not supported by this image
Supported devices: onion,omega2p omega2p
Image check 'fwtool_check_image' failed.

Ideally, I could just add the build model in the profile and build the image for the omega2lte. However, I have tried adding these lines and it doesn't work:

BUILD_MODELS="
onion_omega2
onion_omega2p
omega2lte
onion_omega2lte
"

It just says profile not found.

How can I use the wrapper for the omega2lte?

Thanks in advance

You can install the firmware you included in your post above just add the -F switch:

sysupgrade -F onion_omega2p-22.03.5-20240717.bin

The additional files you need are here:

https://github.com/OnionIoT/OpenWRT-Packages/tree/openwrt-18.06/omega2-lte

You could add the lte to your build but you'll need some more advanced skills like migrating the dts and adding the lte packages to your feeds.

In the image builder packages I was able to include:

IMAGE_BUILDER_PACKAGES="
onion-repo-keys
omega2-base
omega2-base-files
omega2-base-passwd
omega2-ctrl
i2c-tools
omega2-lte-base
"

I am unsure if I need to include the omega2-base and the omega2-lte-base. I just want to be able to prepare firmwares for the omega2-lte with some custom files/packages and not have to worry about firmware mismatching or factory resetting like in the cloning/overlay method.

Here is a link to a patch I created that will add the lte device and include the lte-base in the build. This is a patch for OpenWrt 23.05.3 so you may have to merge it in manually.
