As i read over the web, my model c is featuring a AP6255 WiFi/BT combo which is also a BROADCOM43455 clone.
I cross compiled longterm 5.4.25 kernel on my model c and installed modules. My SBC is booting fine BUT WiFi device is not properly picked up : brcmfmac, brcmutil and cfg80211 modules are loaded though…
In the stock dtsi file, there is this section (for ab i presume…) :
brcmf: wifi@1 {
compatible = "brcm,bcm4329-fmac";
reg = <1>;
interrupt-parent = <&gpio0>;
interrupts = <RK_PA3 GPIO_ACTIVE_HIGH>;
interrupt-names = "host-wake";
pinctrl-names = "default";
pinctrl-0 = <&wifi_host_wake_l>;
};
… i tried to replace bcm4329 by bcm43455 in the code above but the WiFi device is still not properly loaded : no wireless extensions given by iwconfig.
Thanks for any help !
