Hello,
I use no codecs but DSP-Link (until now I modified the
readwrite-example).
Now I need some heap for the DSP-Side.
http://wiki.davincidsp.com/index.php?title=Changing_the_DVEVM_memory_map
says that there is "full 122MB for video algorithms intermediate
processing buffers organized in a hea
ent = "DDR";

I thought this is done through a run of gmake. "gmake" is making a BIOS
from the entries of readwr
& WRITEMEM segments.

mory map.
prog.module("GBL").C64PLUSMAR128to159 = 0x8000 ;
For this, refer to SPRU871.pdf for MAR address ranges and DSP/BIOS
documentation for syntax for the settings.

Thank you for the hint. I changed that to
prog.module("GBL").C64PLUSMAR12
