Hi,


what do u mean with 'build directory'?
The default build directory is l4re-snapshot/obj/ , isn't it?
And this is what i use.

'make clean' already deletes l4-snapshot/obj/.
clean: @$(RM) -r obj


But this cant be it. Some config stuff must be stored somewhere else.
For example, the first time i built l4re-snapshot i had to choose 
between ARM Secure World or Normal World.
When re-building the same snapshot (after 'make clean') it doesn't ask 
me for that, but the previous config is selected, already.

Rebuilding:

'cd l4re-snapshot/'
'make clean'
'make setup'
'make'


Just to clear things up: Re-Building l4re-snapshot-2014022818 works 
great.
But l4re-snapshot-2014022818_TEST does not.

'cd l4re-snapshot-2014022818/'
'make clean'
'cp -r l4re-snapshot-2014022818/ l4re-snapshot-2014022818_TEST/'
'cd l4re-snapshot-2014022818_TEST/'
'make clean'
'make setup'
'make'

Sorry, no output here.
The CPU load just freaks out until Linux terminates the process and 
reboots.

Anyway, this is what i see when manually terminating:

Thank you.
