扫描千兆网口延时TX RX出错

_only · August 29, 2022, 7:36am

固件类型：自行编译的固件
SDK包名称：rk356x_linux_release_20211019
SDK修改内容：无
Log日志：%22echo 1000 >phy_lb_scan%22log.txt.zip

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？

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

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：

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：
