Re: [ECOS] Problem with Hello world

[David LONY <david dot lony at pragmadev dot com>]

Yes I tried to compile with native cygwin tools but it seem to not work...
I will compile another version of gcc toolchain.. (it is perhaps the 
version of these tools which are too old)

But for the ARM question...
I compile eCos with the ARM7TDMI template but when I compile my hello 
world program I can't see the output.
It is normal ?

I compile my program like that :
arm-elf-gcc -g -I arm7tdmi_install/include test.c -Larm7tdmi_install/lib 
-Ttarget.ld -nostdlib

And I try to debug it like that :
$ arm-elf-gdb -quiet
(gdb) file a.out
Reading symbols from /home/lony/a.out...done.
(gdb) target sim
Connected to the simulator.
(gdb) load
Loading section .rom_vectors, size 0x40 vma 0x40000
Loading section .text, size 0x120d4 vma 0x40040

(gdb) l

2
3       main()
4       {
5       printf("Hello\n");
6
7       return 0;
8
9       }
(gdb) r
Starting program: /home/lony/a.out

Breakpoint 1, main () at test.c:5
5       printf("Hello\n");
(gdb) c
Continuing.

But I never get my "Hello", whats wrong? Do you have any idea?

Thanks you.
Best regards

David LONY
