How to install Debian on NAND in A20-MICRO?

[AzHofi]

Hi Guys,
I've installed Debian on NAND, but I have a sata hdd with Debian too, How could I booting from NAND and mount rootfs from hdd?

My opinion is You can't boot directly from sata disk, but dont worry, you can install a small boot partition to nand with kernel (including builtin, not module sata support) and uEnv.txt, where You can set the root partition.

Best regards
Attila

Hi guys,

does anyone have the u-boot source to NAND?

Thanks

Hi Mad Demus!!!!!!!!!
I am using board A20-OLinuXino-Micro-4GB
I am having running SD card with Debian.
I followed the procedure "HOWTO install a running SD-card image to A20-OLinuXino NAND flash"
Procedure is all done...
But when board boots from NAND and displays kernel messages....it stucks at one perticular location
Part of the Log is given below........

I can see 2 penguins of Olimex on my LCD screen.
Please help...where possibly the problem is???

Today I successfully installed the official Debian Image into A20-OLinuXino's flash.

First, download and uncompress this file which contains the bootloader and an image of the flash partition scheme:

http://dtmh.de/files/olinuxino-a20-flashinstall.zip

After that, change into the folder which contains the uncompressed files.

Now, here is the quick recipe:

#############################################################################
# HOWTO install a running SD-card image to A20-OLinuXino NAND flash
#
# The following steps must be executed as root and on a running SD-card image!
#
# Sunxi kernel 3.4.43 or later is required.
# Tested with official Olimex Debian Wheezy image with kernel 3.4.61+
#
# The flash partition scheme will looks like follow:
# /dev/nanda is BOOT device
# /dev/nandc is ROOT device
# /dev/nandb is MAGIC device
#
#############################################################################

# First of all, make sure that all nand devices /dev/nand* are unmounted
# (check output of mount if you are not sure)

# Copy A20 flash partition image to NAND flash

Code Select Expand

tar -xzOf nand_part.gz | dd of=/dev/nand
sync

# reboot to make new partitions available

Code Select Expand

reboot

# after reboot: create filesystems

Code Select Expand

mkfs.vfat /dev/nanda
mkfs.ext4 /dev/nandc
echo -e 'ANDROID!\0\0\0\0\0\0\0\0\c' > /dev/nandb

# mount new filesystems

Code Select Expand

mkdir /mnt/nanda
mkdir /mnt/nandc
mount /dev/nanda /mnt/nanda
mount /dev/nandc /mnt/nandc

# install bootloader to /dev/nanda

Code Select Expand

rm -rf /mnt/nanda/*
rsync -avc bootloader/* /mnt/nanda

# copy script.bin and uImage into new root device under /boot

Code Select Expand

mount /dev/mmcblk0p1 /boot
rsync -avc /boot/script.bin /boot/uImage /mnt/nandc/boot/

# if you need additional kernel arguments, you can create a uEnv.txt file under
# /mnt/nandc/boot/ wich contains the following line:

extraargs=<your extra kernel args here>

# copy rootfs

Code Select Expand

rsync -avc --exclude-from=exclude.txt / /mnt/nandc
sync

# shutdown and remove SD card

Code Select Expand

shutdown -h now

# now power on the device and it should boot from NAND!

Enjoy!

Hello,
I was trying to use this tutorial to install debian on the NAND flash with A20-SOM board. Everything went well, but after reboot without the sd card I could not boot the NAND flash. Are there any additional steps that should be taken that are not described? I Would aprichiate all help.

[JohnS]

How far does it get?  Show console output...

John

[bremenpl]

This is the output of uart debug console:
https://pastebin.com/mgdSP6Zm

[davidahoward]

It looks like it gets to:

VFS: Cannot open root device "nand3" or unknown-block(0,0): error -6
[    3.885981] VFS: Cannot open root device "nand3" or unknown-block(0,0): error -6

[    3.916014] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

[JohnS]

@bremenpl so did you change root= ?

John

[banata]

@JohnS Please be more detailed about root parameter. Where is the file containing this row and what to write after
root = ....?

There are lines in the tutorial:
# if you need additional kernel arguments, you can create a uEnv.txt file under
# /mnt/nandc/boot/ wich contains the following line: (without the leading #)
# extraargs=<your extra kernel args here>

So try to write some parameters there! 

I have another questions:

When I run boot from nand the booting stop here:

HELLO! BOOT0 is starting!
boot0 version : 2.0.0
read dram para.
dram driver version: 1.15
dram size =512MB
0xffffffff
super_standby_flag = 0
Succeed in opening nand flash.
block from 2 to 6
deal block 2
Succeed in reading Boot1 file head.
The size of Boot1 is 0x00068000.
The file stored in 0x00000000 of block 2 is perfect.
Check is correct.

I suppose it will be documented as part of Linux kernel doc.  Or try google.  Or read the sources

Which debian & kernel are you using?

John

[banata]

I,m with a20_Lime_debian_3.4.90_release_3.img and olinuxino-a20-flashinstall from the first post.
This message is in boot.axf file and inside are some binary data and error massages.

I will search around for another file to test with or how do biuld my own.
Boyan

[JohnS]

You're using Lime kernel but not Lime board? Likely won't work.

John

[banata]

Unfortunately it is A20

What do you mean?  Your post is in thread A20-Micro and you said Lime.  It's critical what you use.

Hello,

I would like to compile (and configure) my own bootable images for a NAND. Please can you tell us how did you create the zip file that you provide ?

Do you use u-boot ? How do you compile it (branch, commands) ?

Or which tutorial, documentation, did you follow ?
