我们目前使用Xavier NX模块的eth0网口接到RTL8367RB交换机,第一次上电查看eth0是up的,然后模块reboot后,查看eth0已经down掉了,然后手动ifconfig eth0 up起不来,显示:SIOCSIFFLAGS: Operation not permitted,同时串口打印信息报错:ubuntu login:[ 239.008383] [eqos_poll_for_swr][598][type:0x4][loga-0x0] poll_for_swr:timeout
[239.008617] net eth0: failed to poll MAC Software reset.

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

Is this issue only happened with this RTL switch chip?

Also, not quite sure about your exact connection, is there any schematic to share?

这是打印信息,最后有报错:ubuntu login: [ 26.122354] [eqos_poll_for_swr][598][type:0x4][loga-0x0] poll_for_swr: timeout

Have you validated such design before? Have you checked with switch chip vendor for help? From hardware side, for Xavier NX, it only needs to follow the Design Guide to do routing. I don’t see errors on Xavier side in your schematic. Please check with vendor for that.
