MFG Tool question

[eunseokjung]

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

Eunseok.

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.

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
