brcmfmac、brcmfmac_module_init 无可用平台数据

我已将内核版本从 4.11 更新到5.4.3-g9c2490ac8-dirty #3 SMP PREEMPT Sun Aug 8 12:11:16 UTC 2021 armv7l GNU/Linux

我的 brcmfmac 内核模块有问题。我已启用 brcmfmac 调试并启用调试消息中的所有消息类型。

当我输入以下命令时，您可以看到 dmesg 输出insmod /<path to ko file>/brcmfmac.ko debug=0x1FFFF ：

[ 2526.159218] brcmfmac: brcmfmac_module_init No platform data available.

[ 3249.364285] brcmfmac: brcmf_sdio_exit Enter

执行时我没有看到 wlan0 名称ifconfig -a！

我已在路径中放置了适当的.bin文件.txt/lib/firmware/brcm/


ls /lib/firmware/brcm/ -l
-rwxr--r--    1 root     root        219557 Jun  2 12:28 brcmfmac43362-sdio.bin

问题解决了。我已在 dts 文件中向 usdhc 添加了兼容属性。

&usdhc1 {
    #address-cells = <1>;
    #size-cells = <0>;
    pinctrl-names = "default";
    max-frequency = <50000000>;
    pinctrl-0 = <&pinctrl_usdhc1_alt>;
    bus-width = <4>;
    no-1-8-v;   /* force 3.3V VIO */
    non-removable;
    pm-ignore-notify;
    cap-power-off-card;
//    /delete-property/ wakeup-source;
    status = "okay";

    brcmf: bcrmf@1 {
       reg = <1>;
        compatible = "brcm,bcm4329-fmac";
    };
};

我记得旧版本的 brcmfmac 对此属性不敏感。
