2009-09-10 11:08:05     why can't properly read the DM9000 id?

I am using the u-boot-2009-06 check out from svn, I ported it for my board that has a DM9000 on it. but can't properly read the ID, the DM9000 id is

 

#define DM9000_ID       0x90000A46

 

but what I read is

 

ERROR: resetting DM9000 -> not responding

 

dm9000 not found at 0x203fffbc id: 0x000a4690

 

 

 

I don't know what is wrong, and my EBIU setting is

 

#define CONFIG_EBIU_SDRRC_VAL   0x398

 

#define CONFIG_EBIU_SDGCTL_VAL  0x91118d

 

 

 

#define CONFIG_EBIU_AMGCTL_VAL  0xFF

 

#define CONFIG_EBIU_AMBCTL0_VAL 0x7BB07BB0

 

#define CONFIG_EBIU_AMBCTL1_VAL 0xFFC27BB0

 

 

 

can you tell me what is the problem, thank you.

 

 

 

Regards,

forgot to say, if using the old version of u-boot, the dm9000 can work properly.
