It looks like you have some issue with your device tree. Did you add an overlay? Is so, what is it? For the RPI4 on OpenWrt, this looks something like:

(note that you’ll need to add that fragment to the overlays Makefile - e.g. [morse-feed/examples/bcm27xx/target/linux/bcm27xx/patches-5.15/991-dt-overlays-build-morse-overlays.patch at mm/openwrt-23.05 · MorseMicro/morse-feed · GitHub](https://github.com/MorseMicro/morse-feed/blob/mm/openwrt-23.05/examples/bcm27xx/target/linux/bcm27xx/patches-5.15/991-dt-overlays-build-morse-overlays.patch) - then add a line like dtoverlay=mm\_wlan to your /boot/config.txt)

Someone else brought up the rpi5 here, so you may want to look at their overlays (and packages, for that matter): [HaLow Integration on Raspberry Pi 5](https://community.morsemicro.com/t/halow-integration-on-raspberry-pi-5/88)
