It seems this board ran uncalibrated on BB and CC, which is no longer possible after my patches on trunk. A correct entry needs to be added to target/linux/ar71xx/base-files/etc/hotplug.d/firmware/11-ath10k-caldata in order to upload calibration data to the firmware. It should be rather easy, but if you don’t feel like doing it yourself, I could make a patch if you could tell me where on flash the calibration data and mac address are located.
