Open Embedded / Simple C Programs On Big-endian Xscale

Coll, glad you got it sorted - I'd be interested to know why you got all that binary stuff out though if you ever find out why.

Thank you, i think it is a bug in the crosstool or something... and the make apply the proper patch to it if i use the above building configureation...although im not sure...

Open Embedded / Simple C Programs On Big-endian Xscale

I could getover

I used crosstool 0.38
compile it using

export TARBALLS_DIR=/home/user/crosstool # where it will save source tarballs
export RESULT_TOP=/opt/crosstool # where it will install the tools
export GCC_LANGUAGES="c,c++,java,f77" # which languages it will make compilers for
cd /home/user/crosstool/crosstool-0.38
eval `cat armv5b-softfloat.dat gcc-3.4.0-glibc-2.3.2.dat` sh all.sh --notest

for more info http://kegel.com/crosstool/crosstool-0.38/...tool-howto.html

and it is working now
armv5b-softfloat-linux-gcc hello.c

I was asking about the output as if the code thought it was running in littleendian mode, %d might produce something interesting if the two halves of the number are switched (as the sign bit will produce something).

The output is just like if u had cat a binary file....long one....

I can narrow the problem;
after asking.. it sounds like a bug in the toolchain... which have been batched out

Can anyone show me where to find a tested toolchain to compile to armeb (armv5b) architecture???

Open Embedded / Simple C Programs On Big-endian Xscale

Im trying to develop programs to a target machine wth the following /proc/cpuinfo:

Processor : XScale-IXP4xx/IXC11xx rev 1 (v5b)
BogoMIPS : 266.24
Features : swp half thumb fastmult edsp

Hardware : iDirect Phoenix Platform
Revision : 0000
Serial : 0000000000000000

and uname -a:
Linux iDirect 2.4.24-uc0-iDirect0 #1 Fri Apr 29 16:01:03 GMT 2005 armv5b unknown

as it is Bigendian machine i use
/usr/local/arm-uclinux-tools2/arm-uclinux-elf/bin/atic -mbig-endian

to compile

the hello world is working fine.

i tired to compile a simple program

#include <stdio.h>

int main() {
printf("Hi: %d\n",0);
return 0;
}
the program had compiled well, but when i run the program on the target machine alot of rabush is showed out.

running the following program on the target shows "Segmentation fault" error
#include <stdio.h>

int main() {
char txt[]="Hi from Ahmad!\n";
sprintf(txt,"Hi: %d",0);
printf(txt);
return 0;
}
What is wrong and how to overcome this problem??!!
please help me!!
