Hello Simon,
Well it was me again. I mailed you earlier on regarding this.

Anyway the wiki guide was really useful, got it working now. I got the demo app (dsp module and arm code running , hurray !!! )
I found some paths on the wiki different than the ones that i found in the tool chain. Some tweaks in the Makefil got it all working. Though I couldnt compile the arm side just by setting the gcc to arm-gcc. I had to compile it in scratchbox.

I also found that the dsp bios used in 5.03 which is relatively old. i think the latest dsp bios is 5.35.8 or something like that.
