problems arm-elf-gdb ARM SDT

[ananda dot motte at philips dot com]

I do not know if this question pertains to this mailing list ....(and if not I'll send it to any other proposed mailing lists.......)
I recently managed to build the GNU toolchain for a cross compiler with  arm-elf as target with:

binutils-2.10.1
gcc-3.0.1
newlib-1.8.2
insight+dejagnu-5.0.91_20011023

The arm-elf format produced is recognized by arm-elf-gdb connected to a target simulator.

So now I used the ARM SDT (2.51) debugger to see if it recognizes the arm-elf image format produced by GCC and lo..........
it does not.
Apparently the arm-elf image produced by the propriety arm copmiler even though declared to generate arm-elf image formats modifies
something such that the *.axf files are not pure ELF.
I tried of course changing the GNU generated source file suffix to *.axf but it really does not work, giving the message:
The instruction at "<some address>" referenced memory at "<some address>". The memory cannot be read.

Has anyone who has experienced this before come up with a solution or is what jonathan larmour said in

http://sources.redhat.com/ml/ecos-discuss/2000-05/msg00032.html

definitively correct ???

Has anyone tried using the ADS 1.1 debugger instead of the SDT 2.51 one ?
 (I ask because apparently it has enhanced capacities to understand non ARM tool generated arm-elf format)

Last but not the least has anyone tried debugging GNU toolchain generated arm-elf images via multi-ICE ?
Thanks in advance for any infos....
