Hello, I am trying to integrate mender with OpenWRT. I can’t understand where should I set parameter about ubi layout, because mender doesn’t understand artifact ubi image.`ubiupdatevol` command works normally.  
I have nand flash, ubi layout and 5 ubi volumes:

1. u-boot-env-1
2. u-boot-env-2
3. rootfsA(squashFS)+FIT image (kernel+dtb)
4. rootfsB(squashFS)+FIT image (kernel+dtb)
5. rootfs\_data partition

It successfully connects to the mender server, can see mender-artifact and works well. But when I want to update it downloads artifact and tries to update it as a simple partition, not ubi:

I create artifact with command:  
`mender-artifact write rootfs-image -n fsl_ls1021a-1641064824 -t fsl_ls1021a --software-version r51-bba1547a513 -f openwrt-layerscape-armv7-fsl_ls1021a-squashfs-artifact-1641064824.mender -o openwrt-layerscape-armv7-fsl_ls1021a-squashfs-artifact-1641064824.mender.new`  
openwrt-layerscape-armv7-fsl\_ls1021a-squashfs-artifact-1641064824.mender - ubi volume image with rootfs(squashFS)+FIT image (kernel+dtb)

I found the problem, it is mender.conf file. There should be ubi0\_2 or ubi0\_3 without dev prefix.
