AX210蓝牙识别可用rock5b内核-armbian

AX210蓝牙识别可用rock5b内核-armbian

背景

之前已经给ubuntu做了蓝牙的适配，ubuntu打的内核包并不适用于armbian的，armbian的内核是自己通过一个脚本打出来的，并且armbian下面的编译参数跟ubuntu不同

比如我们需要用到的这个btusb，就是armbian做的buildin的，也就是放内核里面，不是以内核模块处理的，这个地方正常也没有问题，但是这个模块需要加载firmware的，在内核里面是无法加载外面的，需要单独处理

默认的出错显示如下:

root@rock-5b:/lib/firmware/intel# dmesg |grep blue
[    5.090354] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: uart_rts_gpios = 34.
[    5.090374] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: BT,reset_gpio = 102.
[    5.090390] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: BT,wake_host_irq = 21.
[    5.845000] bluetooth hci0: Direct firmware load for intel/ibt-0041-0041.sfi failed with error -2

这个加载的启动5秒就加载了，而在ubuntu下面是14秒左右加载的，通过这里判断应该是firmware的加载问题

相关处理

下载armbian工具

1
git clone https://github.com/armbian/build.git

把编译内核指定到自己的内核

上面的KERNELSOURCE修改为我已经打好补丁的分支的，脚本会自己去下载内核

把固件打到内核里面去

注意上面的FIRMWARE目录就是/lib/firmware，固件的需要把目录带上，否则打不进去
打进去的内核是会在内核编译目录里面看到的，注意下，当前的编译机器的 /lib/firmware/intel/ibt-0041-0041.sfi这个文件路径需要存在，这里是调用编译机器的，弄到内核里面去的

可以看到我们buildin的intel的 firmware

开始编译

1
root@ubuntu:~/armbian/build# ./compile.sh

可以看到我改过的文件，脚本提示了，继续就行

选第一个就行，我们上面改的是linux-rockchip-rk3588-legacy.config这个配置文件，选这个就是指的用这个配置文件


默认是没有的，需要选板子里面找

可以找到rock-5b的选项

根据os选，我的版本这个，选的这个

这个我选的这个

继续
然后就开始了，这个会下载很多东西，网络搞通畅

不用等完全编译完，等内核输出了deb包就可以

差不多就是上面的包，主要安装的就是这个包

1
linux-image-legacy-rockchip-rk3588_22.11.0-trunk_arm64.deb

然后把这个包放到机器上面安装即可，然后重启就行了

没有问题，扫描也可以看到相关的蓝牙设备
