ADC... again...

Hi Everybody,
I get the code from mutzev (
http://www.friendlyarm.net/forum/topic/189?lang=en ), and i managed to
generate my executable that i transfer to the mini via activesync.

When i execute it, i got the following message from serial port :


Exception 'Data Abort' (4): Thread-Id=0448010e(pth=83af8b70),
Proc-Id=044700e6(pprc=8270b8c0) 'adc_dlg.exe',

What is wrong ? 
should i have an adc driver like gpio ? 
is it possible to access every registers in an user application ?
should i make a new nk.bin with the exe inside ???

Please could you give me advices ?
Fred

I take example of FriendlyArm "AD-convert.exe" which is able to convert,
but seems not to have drivers... BUT, i look that in the platform.bib, the
file is set as "NK" ( for me as "kernel" application ). Does it means that
if i put my file in the bib file and regenerate nk.bin, it will work ?
Is it the principles of kernel/user mode ?????
