Netconsole stopped working

Hi Bodhi,

It seems after I updated new u-boot 2015.10 the netconsole stopped working. It seems dockstar can not ping to my serverip. but I can use my another computer to ping the serverip.

I tried to use the old env and your new env for this. either one can ping serverip.
I remember I saw someone also has the similar issue but I can not find it anymore.

Please post your u-boot envs.

I also tried replaced last 3 env with the following but still the same result. says ping failed; host 192.168.2.129 is not alive
only difference is 1 time and 5 times.

fw_setenv preboot_nc 'setenv nc_ready 0; for pingstat in 1 2 3 4 5; do; sleep 1; if run if_netconsole; then setenv nc_ready 1; fi; done; if test $nc_ready -eq 1; then run start_netconsole; fi'
fw_setenv preboot 'run preboot_nc'

Can you ping the serverip after booted into Debian on the Dockstar? If yes, then try reboot the router, and then power up the Dockstar.

Errr.. It was my bad.
missed 1 env and I was on the wrong vm. so definitely can not ping it because the vm wasn't on. lol

Everything is working now. Thanks again for all your help bodhi
