We used CW 10.5.1 program uboot image(512kbytes) into P1010RDB NOR flash, but cw report "Image size is 0 bytes, nothing to erase."

The logInfo of CW operate as follow:

Hi Yiping,

I specify the address as 0xfff80000(because my uboot size is 512KBytes), the board was bootup successfully.

Thanks!

Hi Adrian,

Thanks your efficiently suggest, the issue was resolved after modify the settings of address offset.

I think the program address format is flash base address plus address offset, so it cause I cannot program flash.

my uncorrected settings as follow:

Please use the effective address for u-boot, there are two banks for P1010RDB NOR Flash.

For bank0, please  specify the Address as "fff40000".

For bank1, please specify the Address as "fef40000".

Have a great day,
Yiping

Make sure you have the correct settings.Also, use the correct address offset for programming uboot.
