CPU：RK3288git

系統：Android 5.1less

注：系統中自帶的模塊沒有AP6212，相近的只有AP6210，設置爲AP6210，直接添加固件也能夠正常使用。spa

此文是手動添加AP6212的例程。調試

一、在設備樹中修改 wifi 芯片爲 ap6212，code

kernel/arch/arm/boot/dts/rk3288-tb_8846.dtsblog

-               wifi_chip_type = "ap6330";
+               wifi_chip_type = "ap6212";
 
         sdio_vref = <1800>; //1800mv or 3300mv

二、在 Kconfig 文件中增長 AP6212 選項。ip

/kernel/drivers/net/wireless/Kconfigget

diff --git a/kernel/drivers/net/wireless/Kconfig b/kernel/drivers/net/wireless/Kconfig
index 544aa86..3e1026d 100755

        config AP6234
                bool "AP6234"

三、在配置文件 rockchip_defconfig 中屏蔽舊 wifi 芯片，增長新的 wifi 芯片cmd

kernel/arch/arm/configs/rockchip_defconfigit

diff --git a/kernel/arch/arm/configs/rockchip_defconfig b/kernel/arch/arm/configs/rockchip_defconfig

 CONFIG_INPUT_EVDEV=y
 CONFIG_INPUT_KEYRESET=y

四、此時串口打印中會出現打開文件 fw_bcm43438a1.bin 失敗，須要更新 wifi 模塊固件。

[   18.686420] dhdsdio_download_code_file: Open firmware file failed /system/etc/firmware/fw_bcm43438a1.bin
[   18.686430] _dhdsdio_download_firmware: dongle image file download failed

WiFI 固件路徑：/external/wlan_loader/firmware

將模塊供應商提供的固件文件拷貝到此目錄下，而後編譯燒錄。

external/wlan_loader/firmware/fw_bcm43438a1.bin
external/wlan_loader/firmware/fw_bcm43438a1_apsta.bin
external/wlan_loader/firmware/fw_bcm43438a1_p2p.bin
external/wlan_loader/firmware/nvram_ap6212.txt

編譯後，系統會將模塊固件拷貝到 out/target/product/rk3288/system/etc//firmware/ 目錄下

若是隻是調試，能夠經過 adb 將固件 push 到 /system/etc//firmware/ 目錄下，而後重啓。

kernel/drivers/net/wireless/rockchip_wlan/rkwifi/rk_wifi_config.c

wifi 驅動路徑：kernel/net/rfkill/rfkill-wlan.c

若是器件升級，好比器件爲AP6212A，供應商給的文件問 nvram_ap6212a.txt，則須要修改下面文件。（直接用之前的 nvram_ap6212.txt 也能夠用，但文件不同，不清楚）

五、BT 驅動中增添代碼，支持 AP6212
