I want to build a BalenaOS for an up-board in version 2.29.2 as recommended on Balena Dashboard. But I have an error with resin-image-initramfs and core-image-minimal-initramfs. See the Github Gist for logs : https://gist.github.com/quentin-burg/70bbcc54df1c4546b5d295c9933dfba3
I would recommend using balena-yocto-scripts/build/barys -m up-board (and see the other barys options with --help), not bitbake directly. This is because barys sets up a bunch of things requited for balenaOS in the local configuration. Can you try that one?
This mentioned in https://www.balena.io/os/docs/custom-build/#Bake-your-own-Image as well, if that helps.
