Hi,
I had modified the DSP-BIOS link scale sample application to do some
processing on data on the DSP side.
Problem is that it is running fine upto some iterations and after that
it hangs and giving some kernel panic error at ARM side.
Suggest some methods to resolve this error .Error message is shown
below.
MEMORY MAP USED
prog.module("MEM").STACKSIZE = 0x600000 ;
/*

var DSPLINKMEM = prog.module("MEM").create("DSPLINKMEM");
DSPLINKMEM.base = 0x8FE00000;
DSPLINKMEM.len = 0x100000;
DSPLINKMEM.createHeap = false;
DSPLINKMEM.comment = "DSPLINKMEM";

var RESET_VECTOR = prog.module("MEM").create("RESET_VECTOR");
RESET_VECTOR.base = 0x8FF00000;
RESET_VECTOR.len = 0x00000080;
RESET_VECTOR.space = "code/data";
RESET_VECTOR.createHeap = false;
RESET_VECTOR.comment = "RESET_VECTOR";
