Hear, hear! We do really need something that is specific to
this hw and
avs_kernel, and that is known to work. Otherwise we're
flailing about and not
sure what's causing problems (and resets).

I also second the request for some more information about
the functions compiled
into the avs_kernel.out so that we can use (at least some
of) them to access the
audio hardware, etc. without having to reverse
engineer/guess the functions.

Hello world style audio and video access examples that
compile and run with the
shipped avs_kernel would be great starting points for people
who want to hack on
the DSP.

Regards,


Simon

I should add that it would also make life easier if the
Makefiles, etc., were
ones that work with the 'free' Linux DSP tools. I do wonder
whether Nokia
actually used these tools when developing for the DSP, or
instead the
Windows-based Ti Code Composer Studio ones?

Cheers,


Simon
