[ECOS] Simulator problems on EB40a

[Martin]

Regards

I am trying to run the classic ”hello world” on a simulator for EB40a. I
have done the following:

1) Compiled the ecos: Template: “EB40a”, startup type “rom”, build library

2) Linked and compiled the program: “arm-elf-gcc -g -I
opt/ecos/work/ecos_rom_std_install/include hello.c -L
/opt/ecos/work/ecos_rom_std_install/lib/ -Ttarget.ld –nostdlib”

3) Connect to the target: “arm-elf-gdb a.out”
        GNU gdb 5.3 (eCosCentric)

        This GDB was configured as "--host=i686-pc-linux-gnu --target=arm-
elf"...

   a) tar sim --board=eb40a
        Connected to the simulator.
            
   b) load
        Loading section .rom_vectors, size 0x40 vma 0x1000000
        Loading section .text, size 0xfedc vma 0x1000040
        Loading section .rodata, size 0x2a0 vma 0x100ff1c
        Loading section .data, size 0x378 vma 0x4000
        Start address 0x1000040
        Transfer rate: 534944 bits in <1 sec.

   c) run
        Starting program: /opt/ecos/ecos-2.0/examples/a.out

Afterwards nothing happens. Is it correct that I need to build the tree for
“ROM startup”, when I want to run my program on the simulator without any
monitor? Am I missing anything here? I checked out the eCos CVS about two
weeks ago.
