An OpenWrt 22.03-rc test image is now available.
This should not be too different to what is everyone is using at the moment, as our 21.02 images were using kernel 5.10.
One major change in 22.03 is support for WiFi6/802.11ax using MediaTek MT7915 modules. (ath11k_pci ones will need to wait for master/5.15)
There is a change in the OpenWrt target from
armvirt per feedback on my OpenWrt pull request. Upgrades from our 21.02
arm64 images are supported for both ext4 and NAND (provided you have updated for the squashfs migration).
I am still working on a 22.03 version of μVirt - it should be out in a matter of days.
edit May 23: new build now includes restool support and other fsl-mc patches not present in the previous version
