aic8800-3.0-git20240327.3561b08f-7.tar.gz - TAR+GZIP 壓縮文件, 解包大小為 80,214,670 字節

幸狐的代碼裡面只提供了AIC8800DC模塊WiFi部分的linux驅動（aic8800_fdrv和aic_load_fw），沒有提供藍牙部分的驅動（aic_btusb）。

【下載並編譯aic_btusb驅動模塊】
將幸狐的linux內核文件夾單獨複製一份出來：
cd /home/oct1158/Documents/Code/C/3
cp -r luckfox-pico-aic8800dc/sysdrv/source/kernel .
mv kernel kernel_for_modules

進入複製後的內核文件夾，配置並編譯內核：
cd kernel_for_modules
make luckfox_rv1106_linux_defconfig ARCH=arm CROSS_COMPILE=/home/oct1158/Downloads/arm-gnu-toolchain-14.2.rel1-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf-
make ARCH=arm CROSS_COMPILE=/home/oct1158/Downloads/arm-gnu-toolchain-14.2.rel1-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf-
cd ..

下載並解壓aic8800dc wifi藍牙二合一模塊的linux驅動源碼：
wget https://codeload.github.com/radxa-pkg/aic8800/tar.gz/refs/tags/3.0%2Bgit20240327.3561b08f-7 -o aic8800-3.0-git20240327.3561b08f-7.tar.gz
tar xf aic8800-3.0-git20240327.3561b08f-7.tar.gz

進入藍牙驅動目錄：
cd aic8800-3.0-git20240327.3561b08f-7/src/USB/driver_fw/drivers/aic_btusb/
修改Makefile文件，CONFIG_PLATFORM_ROCKCHIP改成y，CONFIG_PLATFORM_UBUNTU改成n。
找到ifeq ($(CONFIG_PLATFORM_ROCKCHIP), y)下面，KDIR改成內核所在目錄，如/home/oct1158/Documents/Code/C/3/kernel_for_modules。
CROSS_COMPILE改成交叉編譯器所在目錄，如/home/oct1158/Downloads/arm-gnu-toolchain-14.2.rel1-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf-。

make
修改報錯的文件：
aic_btusb.c 第2601行和第2672行 0x%0lx改成0x%0x
            第5121行firmware_info *fw_info = data->fw_info;下一行加上(void)fw_info;
內核目錄/Makefile 第823行注釋掉 #KBUILD_CFLAGS += $(call cc-option,-Wimplicit-fallthrough,)

編譯得到aic_btusb.ko，可上傳到板子上使用。

insmod的時候報錯，提示找不到/vendor/etc/firmware/fw_patch_table_8800dc_u02.bin固件文件。
修改aic_btusb.c文件的第2312行static const char* aic_default_fw_path = "/vendor/etc/firmware"的路徑。
改成"/root/wifi/aic_fw/aic8800DC"（固件放在哪個位置就改成哪個位置）。
make重新編譯驅動模塊，然後上傳到板子上。

[21403.987672] usbcore: registered new interface driver aic_btusb

aic8800dc模塊用的是usb接口，支持windows系統，所以藍牙既可以走uart，也可以直接走usb。
在rv1106木馬派板子上，aic8800dc的藍牙可以用usb接口，不需要飛線接串口。
insmod aic_btusb.ko後，會出現/dev/aicbt_dev這個設備，這個相當於是虛擬的串口設備，
/opt/bluez/bin/hciattach -s 1500000 /dev/aicbt_dev any 1500000 flow nosleep命令可以執行成功。

打開幸狐rv1106的內核代碼，./build.sh kernelconfig
勾選Networking support ---> Bluetooth subsystem support (NEW) （按鍵盤上的y鍵），把裡面所有的東西都勾選上。


編譯內核：
./build.sh
燒錄內核並重啟板子，insmod aic_btusb.ko，裡面就有hci0了。
