扫描千兆网口延时TX RX出错

小山～only

开发板： ROC-RK3568-PC

系统为：buildroot linux
内核版本：4.19
问题：使用命令“echo 1000 > phy_lb_scan”时，无法获得 delayline 窗口，且会发生错误，插网线和不插网线效果一样。
请问该怎么解决这个问题？

这个错误说明你在device/rockchip仓库有改动。。。
你去device/rockchip里看看改了什么，如果不是你改的，那可能你的sdk在解压过程就出现了错误
仓库里执行 git reset --hard HEAD，再同步

buildroot的编译上对Python的版本有要求吗，出现了几个错误，其中一个如下：
2022-08-29T16:46:29 ImportError: cannot import name 'get_env_var' from 'mesonbuild.envconfig' (/home/working/pro/ROC-RK3568-PC/Linux-SDK/rk356x_linux_release_20211019/buildroot/output/rockchip_rk3568/host/lib/python3.8/site-packages/mesonbuild/envconfig.py)

因为之前编译鸿蒙更改过 python 的链接，使其链接到 python3.8，但是更改回 python2 后尝试编译还是出现错误，源于编译 buildroot 时的 host-libglib2 2.68.4 Configuring，其中 import get_env_var 出错，get_env_var 这个模块网上搜不到相关信息，log如下：

meson的找不到“get_env_var”的错误，通过下载对应版本的 mesonbuild 进行替换解决了，但是在编译 recovery 时，libdrm 2.4.109 Configuring 出错了，然而一点出错提示都没有，都不知道错哪了？
