Hi .. You could use MEM_define to allocate your address. I use 0x80030000 which is SDRAM address. You could L2 addres if you want just change this address. #include <c6x.h> #include <mem.h> void main() { void *new_addr; Int seg_id; seg_id=MEM_define((Ptr)0x80030000,0x4B000,NULL); new_addr=MEM_alloc(seg_id,mem_length,0); } --- In , "shia_son" <shia_son@y...> wrote: > MEM_alloc(SEG0, BUFSIZE, 0); > i dont want to open DSP/BISO Config to specify the SEG0 > is there any other way !! |

hi again i did what you suggest and i got this error : undefined first referenced symbol in file --------- ---------------- _MEM_define C:\ti\myprojects\Loop_store\Loop_store.obj >> error: symbol referencing errors - Loop_store.out not built how can this be solved ? :( regards,, --- In , "Henrry Andrian" <henrry@r...> wrote: > Hi .. > > You could use MEM_define to allocate your address.

Currently I am using DSP/BIOS cmd configuration so I didnt have problem with cmd configuration. Myabe you could create one cmd configuration fisrt, and try to implement below code and I think it will be no problem cause I have try it. #include "config1cfg.h" --> It should be your DSP/BIOS header file #include <csl.h> #include <c6x.h> #include <mem.h> void main() { void *new_addr; Int seg_id; Uns mem_length; mem_length 0; seg_id=MEM_define((Ptr)0x80030000,0x4B000,NULL); new_addr=MEM_alloc(seg_id,mem_length,0); while(1); } Good Luck Best Regards, Henrry |
