Re: [ECOS] error: no memory region specified for loadable '.ram_vectors'

Dear Andrew, Ram, Mahmud, and ALL,

Instead of using sparc-elf-gcc (which is produce error message), now I'm 
using sparc-rtems-gcc. sparc-rtems-gcc produce warning ONLY and output file 
created (I don't know wether this 'output file' was the right one).

[agus]$ which sparc-rtems-gcc
    /gnutools/rtems-4.6/bin/sparc-rtems-gcc

[agus]$ sparc-rtems-gcc -I leon_install/include/ ../hello.c -o hello.out -L 
leon_install/lib/ -Ttarget.ld -nostdlib

This GDB was configured as

not in executable format: File format not recognized


The hello.out was created then I enter the following command:
[agus]$ sparc-rtems-objcopy -O binary hello.out hello.bin

Then the hello.bin was successfully created.

Next, I use tsim (evaluation version).
In terminal 1:
[agus@localhost ~]$ tsim-leon3 -gdb

This TSIM evaluation version will expire February 1, 2007

My questions are:

1. Why message: "...hello.bin": not in executable format: File format not 
recognized." turn up?

2. How to create 'the executable file'? I was successfully created ecos 
bootable disk (run in PC, showing hello ecos). I enter command (in cygwin 
environment):

    [cygwin-agus]$ dd conv=sync if=hello.bin of=/dev/fd0

    What should I do to produce the same executable (or bootable <?>) file?

    Thank you very much



Best regards,

Agus
