使用的kernerl -5.2-tf
## 执行adbd 报错，端口监听失败，以为是端口占用了，但是查看没有被占用，初步怀疑是kernel 里的 NET 相关的没有被打开，后来去内核里Networking options 里配置了一番后，发现加载内核的的时候，就卡在了 Starting kernel ... 。。。

结帖 ifconfig 没有回环lo设备，5.2-tf 默认把network options 里的TCP 相关的去掉了，配置上即可，adbd 端口监听就不会失败，
Starting kernel ... 卡在这里。。。。。。。。。。。。。。。。。。。。。。。。。。。### 主要是应该是.config 文件里有手动修改导致编译出来的zimag 有些问题， 基本上按照 https://whycan.cn/t_2794.html 就可以了。。
不知道为啥虚拟机ubuntu 里可以，win10 下确实虚拟出来的是usb串口设备。。。
