The problem about booting from NOR of P2020

[敏赵]

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_BASE

0xeff80000

#define CONFIG_RESET_VECTOR_ADDRESS

0xeffffffc

#define CONFIG_SYS_FLASH_BASE

0xef000000

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

Where am I wrong?

Best regards,

Min Zhao

Dear All,

I have P2020-rdb board and also have codewarrior TAP and IDE.

Please let me know i can have u-boot, uImage and file system in NOR flash, how i can do tftpboot or NFS boot.

Please provide good document or link so that i can flash and boot the board easily.

Thanks,

VP

Did you unset CONFIG_PHYS_64BIT?

[敏赵]

Yes,I don't make 36-bit.

Is the physical address of NOR Flash is 0x4f000000?

In the original memory map of p1_p2_rdb_pc, 0x4f000000 should be DDR.

Have a great day,
Yiping Wang
