Hi, I’m new to Yocto/Mender and I’m working with the imx8mnevk board. I’ve followed the guide (for Zeus), but attempting to get it to work with Kirkstone. I’ve added mender-setup-imx.bbclass, from the Zeus branch, and updated it to the newer syntax. It built without error, but didn’t have any images of use (that I was aware of). Using the Pi before, I added the following: ```auto MENDER_FEATURES_ENABLE:append = "mender-uboot mender-image-sd" MENDER_FEATURES_DISABLE:append = "mender-grub mender-image-uefi" ``` I get the following error: ```auto ERROR: core-image-base-1.0-r0 do_image_sdimg: ExecutionError('/home/chance/mender-imx/build/tmp/work/imx8mnevk-poky-linux/core-image-base/1.0-r0/temp/run.do_image_sdimg.1887472', 1, None, None) ERROR: Logfile of failure stored in:

Hi @chance, Thanks for reaching out! For getting started with the more generic iMX8-stuff, I would suggest to have a good look at the contributed board integrations in [meta-mender-community[([meta-mender-community/meta-mender-nxp at kirkstone · mendersoftware/meta-mender-community · GitHub](https://github.com/mendersoftware/meta-mender-community/blob/kirkstone/meta-mender-nxp)). You might need minor additions to your `local.conf` that reflect the board specifics, which probably includes the location of the `u-boot` environment. Starting out with a `zeus` setup and forwarding is probably problematic. Is this specific board supported there? Plus, pinging @texierp as our iMX8 mastermind. 👍 Greetz, Josef ---

Hi, Thanks for the replies! I was able to build and boot cleanly (using UUU and uefiimg) and the board is now showing up as a pending device. There was some issues with the variable names that were appended to local.conf, such as MENDER\_STORAGE\_DEVICE\_imx8mnevk needing to be just MENDER\_STORAGE\_DEVICE. The only Mender Feature change was: `MENDER_FEATURES_DISABLE:append = " mender-grub"` I instead used: `UBOOT_CONFIG = "sd"` @TheYoctoJester this specific board is not supported there, but there are some other that use the processor that I’ll take a look at, as I want to better understand how it works. @texierp That is the guide I followed. Thanks, Chance ---

Hey @chance, Thats great, congratulations! Two minor things: `MENDER_STORAGE_DEVICE` instead of `MENDER_STORAGE_DEVICE_imx8mnevk` might work for you, but would break other boards. According to the new syntax, it should be `MENDER_STORAGE_DEVICE:imx8mnevk` according to the new override syntax - assuming that your `MACHINE` is `imx8mnevk` The other one: can you provide the final required settings for the board to work? Then we can put those into `meta-mender-community` for helping the next users.👍 Greetz, Josef ---

Ahh that make sense. I caught some of the old syntax when bringing over meta-mender-imx (from zeus branch), but I’m realizing I need to read up on the new syntax more. Perhaps that is related to some of the other issues I was seeing when attempting to add in the other Mender features. I’ll check/update and try again.

Hi @chance, thanks, the `local.conf` looks pretty nice already. So did you actually need to bring over `meta-mender-imx`? What parts of it are really in use? Plus, which layers? If there is no secret sauce involved, or you are able to build for one time without, can you maybe also dump the layer “manifest” thing that bitbake gives you upon startup? I’m just trying to collect all the necessary information for being able to reproduce the build 🙂 Greetz, Josef ---

Hi @TheYoctoJester, Here are the steps I followed: 1. Followed the existing guide but using Kirkstone. 2. Copied meta-mender-imx (Zeus branch) into mender-imx/sourcesmeta-mender-community (Kirkstone) and fixed remove/append/prepend syntax. 3. Copied mender-setup-imx.bbclass (Zeus branch) into mender-imx/sources/poky/meta/classes and fixed append/remove syntax. 4. Modified local.conf. I don’t think a lot of meta-mender-imx was used as it was using the old syntax for board specific variables (\*\_imx8mnevk). I’m realizing I had a bit of luck with it working. Fixing the syntax for the board specific variables in mender-setup-imx.bbclass and it no longer worked at start up, with the following error: ```auto switch to partitions #0, OK mmc2(part 0) is current device flash target is MMC:2 Net: eth0: ethernet@30be0000 Fastboot: Normal Normal Boot Hit any key to stop autoboot: 0 starting USB...

Hi @chance, that layer stack really looks strange, and quite bloated. Have you tried starting with something just like ```auto meta meta-poky meta-oe meta-python meta-freescale meta-freescale-3rdparty meta-freescale-distro meta-mender-core meta-mender-demo ``` and see where you end up? From what I see in `meta-mender-community/meta-mender-nxp` this should get you pretty close already. If at all, then look at the patches that the BoundaryDevices imx8 stuff needs on top. Greetz, Josef
