想用D1开发板设计一个小电脑，搭配蓝牙鼠标键盘远程控制其他设备。因此需要用到XR829的蓝牙部分，现在的问题是：
# hciconfig hci0 up
Can't get device info: No such device
镜像使用https://github.com/YuzukiHD/Buildroot-YuzukiSBC提供的buildroot编译。除蓝牙外，其他的基本正常

其中有一个 [BH_WRN] miss interrupt!，不知道是不是蓝牙错误的意思

个人认为底层蓝牙应该是加载成功的，应该是漏了xradio或者vendor之类的东西导致上面的应用看不到xr829

可能和uart有关系
由于某些原因，需要使用Buildroot才能编译。在使用Buildroot编译后官方提供的手册基本上帮助不太大（绝大部分选项甚至都没有，只有内核部分的配置可以参考）。
目前的情况是，参考官方所提供的手册，把能考虑到的地方都改了，目前可以通过buildroot编译出可以运行XR829固件的系统（因为构建系统方法略有不同，目前还不能运行官方提供的demo验证）。
目前我感觉是XR829已经在正常工作了，包括蓝牙应该也是在工作，我感觉应该是我在配置的时候差了某个环节，导致hciconfig等上层软件看不到底层蓝牙XR829存在（而wifi这边则是正常，可以看到XR829的存在）。
目前我比较怀疑的是漏了xradio，或者vendor的某个环节。

xradio应该存在
破案了，bluez缺少对xradio的支持，即便是D1 SDK里面的bluez 5.55也不包含xradio，需要从全志官网D1 tina中，把bluez的patch抠出来加上来。
hciattach -n ttyS1 xradio
Unknown device type or id
Unknown device type or id指的即是hciattach中不支持xradio，检查方法如下：

hciattach_xradio.c等文件也不一定加入编译，这个时候需要在buildroot configure后，去makefile检查一下。一个简单的检查办法：
搜索tools/hciattach_bcm43xx.c，观察其上下是否有tools/hciattach_xradio.c，tools/hciattach_xradio.c，tools/hciattach_aic.c，以及output/buildroot,是否有对应的.o文件，若没有，手动加上。
