Problem in modify ecos for EDB7312


All,
I am trying to modify ecos V1.3 (based on the
edb7212's) for my edb7312. What I have done on
hal_platform_setup.h is as follow:
 
#define INIT_MEMORY_CONFIG         \
/* Initialize memory configuration  ;\
	ldr r1,=MEMCFG1            ;\
//***	ldr r2,=0x8200A080         ;\
	ldr r2,=0x1f101710		;\
	str r2,[r1]                 ;\
	ldr r1,=MEMCFG2             ;\
//***	ldr r2,=0xFEFC0000     ;\
	ldr r2,=0x00001f13     ;\
	str r2,[r1]            ;\
//***	ldr r1,=DRFPR          ;\
//***	ldr r2,=0x81 /*DRAM refresh=64KHz */      ;\
//***	strb r2,[r1]		;\
	ldr r1,=0x80002300	;\
	ldr r2,=0x00000522	;\
	str r2,[r1]		;\
	ldr r1,=0x80002340	;\
	ldr r2,=0x00000240	;\
	str r2,[r1]
#endif

But it still cannot connect with arm-elf-gdb. Who can
tell me why?

Thanks,

Peihong Li
