Netconsole help

I would like to use netconsole to monitor the boot process on my GoFlexHome unit but am unsure as to how to run it. I've read:-

https://forum.doozan.com/read.php?3,14

but am unclear as to how to run the commands mentioned, eg

fw_setenv serverip 192.168.1.2
fw_setenv ipaddr 192.168.1.100
fw_setenv if_netconsole 'ping $serverip'

Where do I enter these? Do they need to appended to /boot/uEnv.txt on the USB stick I use for booting?

These commands are Linux shell commands. So you would enter them after booted into Debian (or Arch,...).

Not need. fw_setenv set these u-boot envs permanently to flash.

uEnv.txt is a temporary way to set envs during u-boot booting. After you booted into LInux, these setting are no longer there (the u-boot envs are reversed to orginal values in flash).

Also, if you have serial console then skip this netconsole stup. Wait until you have booted successfully with new u-boot, into Debian/Arch, then worry about it.

What would I enter if wanted to get my ipaddr via dhcp?

You will need static IP to get netconsole working. And these 2 are u-boot envs to tell u-boot which computer (serverip) is listening to it, and then how that computer can connect to it (ipaddr).

serverip 
ipaddr
