Wow, @faxe1008 do you have a manifest PR for this? I think we are only supposed to merge it after a successful CI run on the main repo

[faxe1008]

@fabiobaltieri Started drafting it out but encountered some strange errors of seemingly unrelated things I need to investigate. My bad I changed the PR to draft state to prevent any accidental merges.

Any updates on this? It would be incredibly helpful to have LVGL 9.x in Zephyr

[faxe1008]

Hi @Merlin04 I am currently working on monochrome software rendering support which is still missing. You can follow the PR here https://github.com/lvgl/lvgl/pull/6345. This is a prerequisite to get this PR merged.

Since this is merged, any update on 9.x version?

[faxe1008]

@dolence yes, last week there was a v9.2.0 Release. Currently testing everything, this PR will be superseeded by https://github.com/zephyrproject-rtos/lvgl/pull/54

Because from now on I'd like to track the upstream repo directly.
