Hi, all
I'm using MFG tool for burnning bootloader.
When i used this, it showed to me that bootloader was built in offset 0x100000 and 0x200000.
But when i read the flash memory, bootloader wasn't there. Bootloader is existed in 0x100000 and A80000.
Why these different are occurred?
Plz, help this problem to solve
Thank you

Hello,
NAND-based boot loaders do not support XIP approach and should be built to run
in RAM area, but located in NAND (ROM). Special code (primary loader) have to pre-load
the bootloader to RAM area.
Have a great day,
Yuri

The mfg tool mechanism is "boot from usb otg".
It is running a entire system in the DDR including rootfs.
uuc is waiting for command from mfg tool by ucl2.xml.
So a customized mfg tool is a must for a customized board.
