Nandflash migration boot problem

Hello,

I work on a custom Imx6 board : 

    * Model : MCIMX6Q7CVT08AD

    * Nand : MT29F8G08ABABAWP-ITX:B TR

We have a full Yocto bsp made for this board with barebox.

We have recently updated the Nandflash, but the system isn't booting anymore.

The new Nand :MT29F8G08ABACAWP-IT:C

Micron explains how to migrate from one to another on their web site specifying the power cycle is different. I am having a hard time understanding which part of my bsp i should update,

Could you help me about it ?

Best regards,

jc

Hi Jean

for writing new nand image kobs-ng tool is used.

It can be used with Mfg Tool (script mfgtool2-yocto-mx-sabresd-nand.vbs)

i.MX Series Manufacturing Toolkit for Linux 4.1.15_2.1.0 Release

or using steps from third parties, like:

VAR-SOM-MX6 NAND Flash Burning - Variscite Wiki 

Booting from NAND flash on i.MX6-based platforms - DAVE Developer's Wiki 

kobs-ng automatically extracts necessary parameters from nand_ids.c file

nand_ids.c\nand\mtd\drivers - linux-imx - i.MX Linux kernel 

For explanation of new nand "power cycle" suggest to apply to micron tech support:

Hello, 

it did not workout very well :

My current bsp uses Barebox but mfgtool doesn't seem to be compatible with it and flashes U-Boot.

The flash hangs at "Jumping to OS"

I have tried to update the "sb_loader" in our custom flashing tool, but nothing changed,

Regards,

Jean
