Asterisk on mini2440

Hey guys, has somebody tried to port Asterisk on mini2440?? I managed to
cross compile it and install, after that I port it on the board and then
trying tu run. But after typing ./asterisk -vvvvvvvvvvgc the only I see is
"illegal instruction". I was trying use -march=armv4t but then it doesn't
configure. My configure script is: 
./configure --build=i686-linux --host=arm-none-linux-gnueabi
--prefix=/usr/asterisk --disable-xmldoc CFLAGS='-msoft-float -mtune=arm920
-O0' CXXFLAGS='-msoft-float -mtune=arm920 -O0'

Somebody can help me??

If you are FTP'ing to the board make sure binary transfer is on. 

My first couple proggy's suffered from this.

Yeah I know that, but I was copying it on SD card. I think it's something
with configuration. But I'm a newbi with linux and cross compiling,  I need
it to my project.
