I am using BD-SL-iMX6 with Debian stretch, kernel 4.9.x . https://boundarydevices.com/debian-stretch-9-0/
I enabled some kernel config to get the `netem` tool working.
Right now following are the observations on BD-SL-imx6 board:
- Without the LAN cable plugged in the board, everything works fine - the bootup, running gst-commands, access from PC via serial console etc.
- When the LAN cable is plugged in, the board restarts automatically, and the connection to PC via serial console is blocked. I cannot access the board using the console from my PC.
- This behaviour is observed till the LAN cable is plugged out, after which the console works again and there are no issues.
I do not understand why inserting a LAN cable affects the console and leads to reboot of board. I have tried flashing the old kernel image, without any modification and it still shows the same behavior.
I particularly see this message during bootup :

I fail to understand the reason for the behaviour of ethernet port here. Does anyone have any hints?
