am335x 如何添加RTL8723BS这个WIFI+BT模块



SDK-PROCESSOR3.02版本

我们想在板子上添加RTL8723BS的wifi+bt模块,想请教下以下问题:

1.RTL8723BS的驱动是否在SDK种已经存在?我在.config里面好像没有找到8723bs的配置。

2.DTS文件该如何修改?sdk的环境里没有am335x系统有WIFI+BT的样例。

  • 可以在make menuconfig里面找找,看看有没有RTL8723BS的驱动

  • 您好:

    SDK没有RTL8723BS这个模块.我找供应商要了对应内核的驱动,然后编译成功后发现MMC2未成功加载。调试信息中没有mmc2的输出信息。dts如下:

    需要如何修改?另外,wifi相关的需要在dts中添加吗?

    &mmc2 {
    /* these are on the crossbar and are outlined in the
    xbar-event-map element */
    dmas = <&edma 12
    &edma 13>;
    dma-names = "tx", "rx";
    status = "okey";
    vmmc-supply = <&wlan_en_reg>;
    bus-width = <4>;
    pinctrl-names = "default";
    pinctrl-0 = <&mmc2_pins_default &wlan_pins_default>;
    ti,non-removable;
    ti,needs-special-hs-handling;
    cap-power-off-card;
    keep-power-in-suspend;

    #address-cells = <1>;
    #size-cells = <0>;

    };
