标题: 扫描千兆网口延时TX RX出错
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：

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？

详细的报错信息在SDK根目录下的br.log里面应该有
这些都是环境问题，但你之前都编译过，怎么现在会出问题，想一想你改动了什么
或者尝试删除buildroot/output/rockchip_rk356x_recovery目录重编译

成功编译了固件：ROC-RK3568-PC-2CAM_Buildroot_v1.3.0a_220830.img
但是使用命令“echo 1000 > phy_lb_scan”时，还是无法获得 delayline 窗口
且 debug 串口灵敏性下降，现象如下：
[root@RK356X:/]# ls
sh: l: command not found
[root@RK356X:/]# ls
sh: s: command not found
[root@RK356X:/]# l

有官方的1.3.0a的固件吗，你们那边编译完测试有这种现象吗

我是到该文件目录下执行的
cd /sys/devices/platform/fe010000.ethernet/
echo 1000 > phy_lb_scan
指令执行没啥问题，执行完有消息打印，但是没有窗口，可以看我发帖时提交的 log 文件
那个串口不灵敏的问题是 1.3.0a 版本有的吗还是官方固件没有这个问题
