How to porting u-boot to my own board?

Hi LiangYi,

> cfi_flash.c:343: undefined reference to 'monitor_flash_len'

Did you modify cfi_flash.c? My version has no reference to monitor_flash_len at line 343 -- it shows

up in the statement at line 348. Just as a sanity check, your code should look like this:

#if (CFG_MONITOR_BASE >= CFG_FLASH_BASE) 
        && (CFG_MONITOR_BASE <= CFG_FLASH_BASE + CFG_FLASH_SIZE)
        flash_protect (FLAG_PROTECT_SET,
                        CFG_MONITOR_BASE,
                        CFG_MONITOR_BASE + monitor_flash_len  - 1,
                        flash_get_info(CFG_MONITOR_BASE));# endif

Check your config macro definitions. This should not even be compiled, unless you are trying

to run u-boot out of flash.

> Furthermore, My flash is 16-bit width, should I define FLASH_CFI_16BIT in my board.h.

No, it is defined in include/flash.c. The CFI code determines the width automatically.
