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

Thx you,Jesper,
I checked the datasheet for EDB7312. Because the
EP7312 (MCU) provides a SDRAM controller, the
initialization for SDRAM (such as mode data writing)
should be operated automatically.

SDRAM init usually involves writing mode data to the SDRAMs themselves
too. Don't ask me how to do it for your board though.

Thx, Dan
I have setup the registers for SDRAM -
SDCONF(@0x80002300)=0x00000522 and
SDRFPR(@80002340)=0x00000102.
Is there anything else for SDRAM init?

Are you initializing the sdram controller? You can't use the on board
sdram until you do, and chances are gdb wont load at all until sdram is
available.
