One thing to add:

I managed to run tftpd-hpa server on my debian box and tried to update
kernel to nor0.kernel. I run:

update -t kernel -d barebox -d nor -m tftp -f barebox.bin

Which gave me output [1], obviously tftp is wrong configured. When I
mount with filesystem tftp and copy with cp I get the files.

Well I did the same with barebox, just to make sure. It also ereased
first and then complained it cannot run tftp (I had probably an
interrupt at my brain to perform that action ;) )

With barebox still in ram I tried to rescue it somehow..

So i copied barebox.bin from my tftp drive. created empty file tftp in
/env/bin and got a promising output [2], i tried to unprotect the nor
flash just to make sure.

Now where there is supposed to be barebox loading, there is nothing :)
My barebox is gone.

Thanks for comments, Greetings,

Adam
