[BusyBox] boot problem

[Magnus Damm]

Hi again,

I don't know much about the arm toolchain, sorry.
Just make sure that you always use the correct cross-tools,
ie use arm-linux-objdump or whatever you prefix is... 

And then you have cpu-flags and stuff like that.

I would get a precompiled static "known good" binary and
see if that works.
