a : config 部分必须选择
Device Drivers ---> Network device support ---> Wireless LAN ---> Rockchip Wireless LAN support --->
[*] build wifi ko modules
[*] Broadcom Wireless Device Driver Support --->
选择好路径:
(/system/etc/firmware/fw_bcm43752a2_pcie_ag.bin) Firmware path
(/system/etc/firmware/nvram_ap6275p.txt) NVRAM path
Enable Chip Interface (PCIe bus interface support) --->
选择好pcie 接口
(X) PCIe bus interface support
b:检查内核Wi-Fi配置,打开如下几个配置:
CONFIG_WL_ROCKCHIP=y
CONFIG_WIFI_BUILD_MODULE=y
CONFIG_BCMDHD=y
CONFIG_AP6XXX=m
CONFIG_BCMDHD_PCIE=y #PCIE接口,与SDIO互斥,不是PCIE可不配
CONFIG_BCMDHD_SDIO=y
c:确认6275p的几个需要的文件:
wifi:
clm_bcm43752a2_pcie_ag.blob
fw_bcm43752a2_pcie_ag.bin
fw_bcm43752a2_pcie_ag_apsta.bin
nvram_AP6275P.txt
BT:
BCM4362A2.hcd
fw_path=/system/etc/firmware/fw_bcm43752a2_pcie_ag.bin
nv_path=/system/etc/firmware/nvram_AP6275P.txt
clm_path=/system/etc/firmware/clm_bcm43752a2_pcie_ag.blob
conf_path=/system/etc/firmware/config.txt
确认以上文件在系统中
d:DTS 中配置:
vcc3v3_pcie: gpio-regulator {
compatible = "regulator-fixed";
regulator-name = "vcc3v3_pcie";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
enable-active-high;
gpio = <&gpio0 RK_PB5 GPIO_ACTIVE_HIGH>;
startup-delay-us = <5000>;
vin-supply = <&dc_12v>;
};
&pcie2x1 {
reset-gpios = <&gpio0 RK_PB6 GPIO_ACTIVE_HIGH>;
vpcie3v3-supply = <&vcc3v3_pcie>;
status = "okay";
};
&combphy1_usq {
status = "okay";
};
&combphy2_psq {
status = "okay";
};
&csi2_dphy_hw {
status = "okay";
};
&csi2_dphy0 {
status = "disabled";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
mipi_in_ucam0: endpoint@1 {
reg = <1>;
data-lanes = <1 2>;
};
mipi_in_ucam1: endpoint@2 {
reg = <2>;
data-lanes = <1 2 3 4>;
};
};
port@1 {
reg = <1>;
#address-cells = <1>;
#size-cells = <0>;
csidphy_out: endpoint@1 {
reg = <1>;
remote-endpoint = <&isp0_in>;
};
};
};
};
其中 :
gpio = <&gpio0 RK_PB5 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio0 RK_PB6 GPIO_ACTIVE_HIGH>;
对应原理图中:
注意:此io不能配置错误会导致一下问题:其中红色就是因为resetIO 无法获取导致无法使能PCIE设备无法工作 出现PCIE 获取不到任何设备信息dhdpcie_dongle_attach : failed to read PCI configuration space!,导致无法load fireware

任何无法开启wifi 的问题应该先测试以下IO 要均为高
另外linux 5.10的版本buildroot使用的Z:\linux-arm\rk3568_linux5.10\external\rkwifibt\drivers\bcmdhd 下的驱动,和kernel 驱动无关系
external/rkwifibt/
firmware目录:包含各个厂家WiFiBT的firmware文件
drivers目录:包含各个厂家的WiFiBT驱动
bin目录:主要是原厂预置的一些二进制文件
sh目录:主要是开机的WIFIBT的加载脚本,及测试脚本等
S36load_*: WiFiBT开机ko加载及初始化脚本
标准配置:
device/rockchip/rk3xxx/BoardConfig-xxxxxx.mk
export RK_WIFIBT_CHIP=AP6275_PCIE
# Define BT ttySX
export RK_WIFIBT_TTY=ttyS8
单独编译
./build.sh rootfs && ./build.sh firmware
开机自动加载WIFI KO 重要
# 原始文件位置如下,它经过./build.sh 或者make rkwifibt-rebuild编译后会被拷贝
到/etc/init.d/目录下(每次修改后需要重新编译打包)
catexternal/rkwifibt/SXXload_wifi_xxx_modules
...
insmod WIFI_KO # 内容为通用的名字,在编译期间会根据rkwifibt的配置进行替换
...
# 通过menuconfig的配置及buildroot/package/rockchip/rkwifibt/Config.in & rkwifibt.mk
的编译规则.
# rkwifibt.mk 内容节选如下,WIFI_KO被替换成实际配置的ko名字
$(SED)'s/WIFI_KO/\/$(FIRMWARE_DIR)\/lib\/modules\ ... ...
# 查看编译后的文件内容
catbuildroot/output/rockchip_rk3xxxx/target/etc/init.d/SXXload_wifi_xxx_modules
... ...
#可以看到Wi-Fi KO被替换成实际配置的ko,
正常的加载log:
