running eCos under sid

[Mathieu Lacage <mathieu_lacage@realmagic.fr>]

hi all,

Because I am trying to avoid launching my vmware/win2k/arm simulator, I
decided to try to use sid to run a hello-world with eCos...

I built an eCos kernel for the INTEGRATOR ARM development card. Then, I
built a hello world with:
arm-elf-gcc -I/infinite/ecos/ecos/test_install/include
-L/infinite/ecos/ecos/test_install/lib -Ttarget.ld main.c -o main

I got a 1.3 MB elf binary which I tried to run in sid (yesterday's CVS)
with:
arm-elf-sif main
which gave:
bash$ arm-elf-sid -EL main
Fault (memory, 0x1a000004) pc=0x8048

I am not really experienced with such embedded systems. I can imagine
twenty thing which went wrong. (such as wrong start address,
incompatible libc, etc...). So, I tried to run a gdb thing in sid:
arm-elf-sif -EL --gdb=1024 main 
which seems to get into an infinite loop because sid never returns.

So, I tried to connect my gdb to this gdb stub with:
bash$ arm-elf-gdb main

This GDB was configured as "--host=i686-pc-linux-gnu

(gdb) target cisco localhost:1024
which also seems to hang into a loop.


Any comments are welcome.
