Heap Allocation On 5510DSK - Abhishek Dixit - Nov 4 2:37:00 2005
Dear All,
For implementing video decoder I have changed target board to
TMS320VC5510DSK from TMS320C6416DSK. But I am having problem in
allocating heap size. The dynamic memory allocation during code
execution fails at very early stage even though much memory is still
left unused. May be I am unable to allocate memory for heap. What's the
solution for this problem? The contents of cmd file and linker options
and a portion of map file are given below.
Thanks CMD File:
MEMORY
{
ISRAM (RWIX): origin = 00FF0h, length = 02F000h
BSSRAM (RWIX): origin = 030000h, length = 010000h
BSSRAM1 (RWIX): origin = 040000h, length = 020000h
RAM (RWIX): origin = 060000h, length = 02000h
SDRAM (RWIX): origin = 062000h, length = 010000h
SYSRAM (RWIX): origin = 072000h, length = 0d000h
SYSRAM1 (RWIX): origin = 080000h, length = 0300000h
