Hi @kacf,
We have patches for `meta-mender` to generate a mender artifact using an uefi capsule, but that class will be dependent on the `meta-arm` layer, which uses the edk2 tool to package the image/firmware into an UEFI capsule.
Since [**meta-arm**](https://git.yoctoproject.org/meta-arm/) has active development branches as `langdale` and `master`, therefore when looking at compatibility the `master` of meta-mender only has [**kirkstone**](https://github.com/mendersoftware/meta-mender/blob/master/meta-mender-core/conf/layer.conf)?
We have the current patches for `meta-arm` → `master` in progress
[https://lists.yoctoproject.org/g/meta-arm/message/4333](https://lists.yoctoproject.org/g/meta-arm/message/4333)
[https://lists.yoctoproject.org/g/meta-arm/message/4334](https://lists.yoctoproject.org/g/meta-arm/message/4334)
[https://lists.yoctoproject.org/g/meta-arm/message/4335](https://lists.yoctoproject.org/g/meta-arm/message/4335)
[https://lists.yoctoproject.org/g/meta-arm/message/4336](https://lists.yoctoproject.org/g/meta-arm/message/4336)
Which probably will not get backported to `meta-arm` → `kirkstone`
Any thoughts, please?
Thanks,
Vikas

Hey @jainvikas8,
The meta-mender/master will stay on kirkstone until the next Yocto LTS release comes out. If you cannot use kirkstone, then the answer to your question from 18d ago is: Yes, you should use master-next. We will not be testing this branch, but we guarantee that all patches that land there will be included in the next LTS branch, once that time comes.
I updated master-next just now, so it should be in sync with the latest changes on master. If you need any other post-kirkstone patches in there, feel free to include them in a pull request as well.
