新版不支持ipv6；
和以前版本一样，频繁报错，usb和CPU相关错误：

补充:
usb报错是因为我只用usb供电，改为电源适配器后不再报错，希望能适配仅用usb供电;
CPU报错也仍很频繁，希望改进

ales 高手呀！会不会是你刷错型号了？

bug至今未修复。自问自答吧，无意中找到了解决方法，虽然不知道啥原理。
#查看错误日志，注意包含'ERROR-HI_PM]:cpu_volt_otp_adjust_dms'错误出现的最后时间。 journalctl -xe | tail #安装 apt install cpufrequtils #设定CPU频率 cpufreq-set -f 2GHz
编辑/etc/default/cpufrequtils
ENABLE="true" GOVERNOR="conservative"
修改
/etc/init.d/cpufrequtils，GOVENOR改为
conservative，MAX_SPEED改为2GHz，其他按需修改
禁用ondemand模式
systemctl disable ondemand systemctl daemon-reload
重启后查看日志
