When the saveenv command is issued, is there any indication that it has completed successfully?

I changed a couple of environment variables and waited and waited to see some acknowledgement, but saw nothing so rebooted, but the variables were unchanged.

How long should such a process take?

That should be immediate.

Start netconsole, power up the GFHome, interrupt netconsole and,

setenv test_123 yes
printenv test_123
setenv test_123 no
printenv test_123

And please post the log here.

After entering printenv ncip the system just hung. As you can see test_123 was saved OK using saveenv. I'm trying to change serverip and ncip although I'm not sure how they inter relate. Is ncip used as the target for nc output? And can serverip be used for using tftp?

Ideally, I'd like to boot using tftp only if an image is available.

So that proved there is no problem saving env.

The only IP addresses that you should change are ipaddr and serverip. ncip is generated and used by netconsole, that's why it hang when you change it (connection was lost). serverip is used for all network servers upon boot that this box talks to: netconsole and tftp.

On another system I successfully changed ipaddr and serverip but ncip did not change. It remained as 10.10.10.5. I also noticed on this system there was also an ncipk which was set to 10.10.10.4.

I'm booting using kwboot, but wanted to see the output on a remote system so wanted to use netconsole but it isn't working.

balanga,

No, it will not work. When you boot with kwboot, the internal envs are used (the envs area has not been flashed), therefore netconsole won't work.
