Hi All

AIM:
I am using the EB40 board and I am trying to test a simple "hellow
world" application.

Problem:
The memory footprint of the application is too big to fit into the
available RAM. The failure happens during uploading of the
application.

Here's more information of my steps:

1. I used "ecoconfig EB40" to setup and build redboot for the EB40 board.
2. I used "arm-elf-gdb redboot.elf" , tar rdi /dev/ttyS0, set
$cpsr=0xd3, load, cont, Crtl Z, minicom
3. RedBoot> load -b -m xmodem -b 0x02033428             # My notes:
0x02033428 is the lower range of the available RAM as reported by
'version' command on RedBoot
4. I comppile and link my test app
/opt/ecos/gnutools/arm-elf/bin/arm-elf-gcc -c -o test.o -Wall
-I/home/socrates/work/atmel/020606-ARM/install/include test.c
/opt/ecos/gnutools/arm-elf/bin/arm-elf-ld -nostartfiles -nostdlibs
-L/opt/ecos/gnutools/arm-elf/arm-elf/lib
-L/opt/ecos/gnutools/arm-elf/lib/gcc-lib/arm-elf/3.2.1/ -o test test.o
-T/home/socrates/work/atmel/020606-ARM/install/lib/target.ld

socrates@would:~/work/atmel$ ls -l test*
-rwxr-xr-x  1 socrates  socrates  322442 Jun  6 12:06 test
-rw-r--r--  1 socrates  socrates     138 Jun  6 11:35 test.c
-rw-r--r--  1 socrates  socrates     880 Jun  6 12:06 test.o

Here's is my test.c file:
*************************************************************************
#include <cyg/infra/diag.h>

char *RedBoot_version = "aslkjdahlsdfjk";

int main(void)
{
   diag_printf("HELLO WORLD\n");
   return 0;
}
**************************************************************************


I'd really appreciate your help.

Oh, I am very very new to EB40 or ecos for that matter.



Kind regards;

Socrates
