The problem about booting from NOR of P2020

Hi,

We are designing a product using p2020cpu refering to the design of p2020rdb-pc,booting from NOR. We use the u-boot of p1_p2_rdb_pc. It can work.

Now I want to modify the NOR's base address to 0x4f000000. So I modify the following codes in p1_p2_rdb_pc.h :

 

#define CONFIG_SYS_TEXT_BASE0xeff80000
#define CONFIG_RESET_VECTOR_ADDRESS0xeffffffc
#define CONFIG_SYS_FLASH_BASE0xef000000

 

But then the board can't work. It's blank in minicom.

Where am I wrong?

 

Best regards,

Min Zhao
