Ppogram u-boot, image to NAND use Host Server

eugenevolkov — Sat, 06 Jun 2015 10:07:59 GMT

Hi. I would like to load u-boot and image to NAND use NFS.

Is there a document that describes how to do it!

I use yocto relise 3.10.53 for my custom board (not sabreeAI)

I have u-boot, dtb, zimage, rootfs, and i can load board from NFS.

How do I load it all in NAND flash.

I can't use MFG_Tool, because it is a long way to go, because I need to make specific u-boot, image. And not the fact that this process will be successful,

as the full instructions allow to pass this way simply does not.

What is written, but it does not work!

I got to download u- boot, use kobs-ng utility

kobs-ng init -x -v /boot/u-boot.imx

This is what I found on the forum.

But how do I load DTB file, and zimage file use kobs-ng?

I ask the experts Freescale to respond

Hi.

Maybe someone will be useful

# kobs-ng init -x -v /boot/u-boot.imx

# flash_erase /dev/mtd1 0 0

# nandwrite -p /dev/mtd1 -p /boot/zImage

# flash_erase /dev/mtd2 0 0

# nandwrite -p /dev/mtd1 -p /boot/imx6dl-sabreauto.dtb

# flash_erase /dev/mtd3 0 0

# ubiformat /dev/mtd3

# ubiattach /dev/ubi_ctrl -m 3

# ubimkvol /dev/ubi0 -Nrootfs -m

# mkdir -p /mnt/mtd3

# mount -t ubifs ubi0:rootfs /mnt/mtd3

# tar -C /mnt/mtd3 -jxvf /boot/core-image-minimal.tar.bz2

The whole process was successfully.
