revive a bricked NSA320 (3 replies)

Hello,
i have two NSA-320's, one is perfectly working(with latest u-boot and debian), the other one gives me headaches.
It is the one i wrote about in this thread:http://forum.doozan.com/read.php?2,24478,24478#msg-24478.
Now I managed to get serial access, but the thing stays dead otherwise.
I cannot ping the devices' IP, and it does no dhcp requeston itself. But when i issue "dhcp" at the serial prompt, it requests and gets an IP, but after that still doesnt respond to pings.

this is what i see on the serial port:

When i type "boot" , it boots a linux kernel(so it says), but there is no further output on the serial console.

Uncompressing Linux.............................................................................................................................................................................................................................................................................. done, booting the kernel.

There is no more output after that.
I tried to setup a netconsole( nc-klu 6666 on my mac), but there is no response, and no linux booting, as far as i can tell. The very same netconsole works perfectly on my other NSA320.
I tried to "setenv stdout=nc" , "setenv ncip=10.9.1.200"and then "saveenv", to no avail.
Even trying to change minor things like "setenv bootdelay=10" just makes the whole bootdelay variable disappear...

Any ideas how to go from here?
