Hi @zapados,
To be honest I’ve never used kas before - and am not a big fan of it - but I believe your issue will require some deeper digging into Yocto which might not be possible with kas.
Second, I see you have a long list of layers in your bblayers.conf. I’d suggest first making a build with only necessary layers required (mender, bsp and poky related layers). After you set up the most simple build, and get Mender to work on it, I’d suggest adding more stuff to it. This way not only does the build finish faster, but debugging it is easier and it’s more clear what’s going on.
What Mender layers should I be including?
I believe meta-mender-core is sufficient in your case.
Do you think I should start tackling the manual u-boot integration based on the fact that there is no
mender_stuff in my u-boot environment?
That’s exactly what I would do next.
Lastly, I want to point out that the board you’re using has not been tested with Mender before. (source) Because of it, integrating Mender on it could be more difficult than it seems. Sorry I couldn’t be of more help.
Best of luck,
Jana
