Dear Dudy,
Thanks for your suggestion.
I have another question.Can your loader load the dsp executeable to the
dsp's private L1 or L2? Is it necessary to load some section of dsp's
executeable to the L1 or L2?
It seems that the loader in dsplink can't loader the dsp executeable to the
dsp's private memory space.
Best regars,
Qi Huafei
Hello,
We use our own loader to upload code and start the DSP.
The code ran but it was very slow - The problem was that
The Caches (L1D L1P L2) were not enabled. Maybe this could
be your problem?
Cheers
Rudy.
