Good day!
I’m trying to activate Wi-Fi and Bluetooth (AP6256) for Radxa E25 on kernel 6.1.59 using the Radxa’s ‘bsp’ (/linux/stable) and ‘debos-radxa’ (bullseye) development frameworks. Could you please help me with this question:
- I started trying with ‘brcmfmac’ driver and I created patches for device-tree and kernel configuration:
Additional device-tree params

Base config is the same as /linux/stable in bsp. Also i added symbol link for firmware in firmare/brcm directory for board.
But kernel with these patches doesn’t start as expected:

What am i missing with device-tree/kernel flags?
P.S. On Linux kernel 4/5, Rockchip provided a custom “wlan-platdata” and “bluetooth-platdata” drivers. What main difference between these drivers and brcmfmac?
Thank you in advance for your help,
