Cb3 Lubuntu-12.10-desktop Nand Installation 20131015-build

Abstract

Cubietruck is the 3rd board of cubietech, which is also named cubieboard3. The board features an Allwinner A20 ARM Cortex-A7 dual core

processor with Mali 400 MP2 graphics, 2GB of RAM, HDMI, Gigabit Ethernet, WiFi, Bluetooth, and a microSD card slot. There’s nothing too

surprising in those specs, but here’s what sets this developer board apart from a tablet with its screen ripped off. The Cubietruck has a SATA

2.0 interface, 2 USB host ports, SPDIF, a headphone jack, IR port, and 4 LED lights. It also has 54 extended pins including UART, PS2, and a

bunch of other options. Read more about cubietruck, please refer to here [http://docs.cubieboard.org/products/start].

Lubuntu is a fast and lightweight operating system developed by a community of Free and Open Source enthusiasts. The core of the system is

based on Linux and Ubuntu . Lubuntu uses the minimal desktop LXDE, and a selection of light applications. It's official site is lubuntu

[http://www.lubuntu.net/]

The Cubie team have ported cubietruck to lubuntu-12.10-desktop, here is a guide for installing lubuntu-12.10-desktop to cubietruck nandflash.

Flash to Board

When seeing the prombt, you have enter the FEL mode. Select Yes to continue




Congratulations! You have finished the installation process. Enjoy your Cubie and Lubuntu Desktop!

When you first start up the system, It will take about 2 minutes to initialize the system. Also we suggest you have the ethernet cable connected

when booting, to avoid waiting DHCP timeout.

Customizing

Changing Boot Parameters

If we want to change boot parameter, say, we want to add "hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1920x1080p50" to the

kernel parameter:

$wget http://dl.cubieboard.org/software/a20-common/mk_env_fex.tar

$tar -xf mk_env_fex.tar

$cd mk_env_fex

$vim env.cfg

Change the content below

...

loglevel=5

extras=hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1920x1080p50

#set kernel cmdline if boot.img or recovery.img has no cmdline we will use this

setargs_nand=setenv bootargs console=${console} init=${init} loglevel=${loglevel} ${extras}

setargs_mmc=setenv bootargs console=${console} init=${init} loglevel=${loglevel}

#nand command syntax: sunxi_flash read address partition_name read_bytes

..

$mk_env_fex

copy env.fex to lubuntu OS, then dd if=env.fex of=/dev/nandb bs=1M

Changing Kernel




Getting The Kernel Source

The kernel source matching this image is here [http://dl.cubieboard.org/software/a20-

cubietruck/lubuntu/ct_lubuntu_desktop_12.10_20131015/linux-sunxi.tar.gz]. And the defconfig is here [http://dl.cubieboard.org/software/a20-

cubietruck/lubuntu/ct_lubuntu_desktop_12.10_20131015/kernel_defconfig].

Please also refer to

http://github.com/linux-sunxi

http://github.com/cubieboard2

Compiling

$tar -zxvf linux-sunxi.tar.gz

$cp kernel_defconfig linux-sunxi/.config

$cd linux-sunxi

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage modules

$objcopy -R .note.gnu.build-id -S -O binary vmlinux bImage

$mkbootimg --kernel bImage \

--ramdisk rootfs.cpio.gz \

--board "sun7i" \

--base 0x40000000 \

-o "boot.img"

Note: mkbootimg command can be found at this package [http://dl.cubieboard.org/software/a20-common/mk_env_fex.tar]

Replacing

Copy boot.img, modules to your lubuntu system,

#dd if=boot.img of=/dev/nandc bs=1M

Note: You should be skilled in kernel building, else it's easy to damage your OS system.

Building Custom Modules

Download Kernel Source

$wget http://dl.cubieboard.org/software/a20-cubietruck/lubuntu/ct_lubuntu_desktop_12.10_20131015/linux-sunxi.tar.gz

$wget http://dl.cubieboard.org/software/a20-cubietruck/lubuntu/ct_lubuntu_desktop_12.10_20131015/kernel_defconfig

Extract and create local git repo

$tar -zxf linux-sunxi.tar.gz

$cp kernel_defconfig linux-sunxi/.config

$git init

$git add .

$git commit -m "init a repo just for match the uname -r token" -a

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig

$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage

$cd $your_kernel_module_path_and_point_your_kdir_here

...

Copy your new module to your lubuntu OS

TBD

C/C++ Programming

lubuntu-12.10-desktop is quite a modern operating system, that we can do almost all language programming, including C/C++, JAVA, Python,

Perl, and so on. To support C/C++ programming, just run the following command:

#apt-get install build-essential

To become more productivy, you can also use VIM or EMACS

#apt-get install vim emacs cscope cscope-el

Tips

About Partitions

Partitons Layout

We have 5 partitions on the system, nand represent the whole nandflash. Nand[a-e] are treated as partitons

root@cubietruck:~# ls /dev/nand* -l

brw-rw---- 1 root disk 93, 0 Oct 15 08:46 /dev/nand

brw-rw---- 1 root disk 93, 1 Oct 15 08:46 /dev/nanda

brw-rw---- 1 root disk 93, 2 Oct 15 08:46 /dev/nandb

brw-rw---- 1 root disk 93, 3 Oct 15 08:46 /dev/nandc

brw-rw---- 1 root disk 93, 4 Oct 15 08:46 /dev/nandd

brw-rw---- 1 root disk 93, 5 Oct 15 08:46 /dev/nande

/dev/nanda

Contains the bootlogo, script.bin, and so on

root@cubietruck:~# ls /mnt/nanda/

boot.axf drv_de.drv font24.sft linux os_show script.bin

boot.ini drv_hdmi.drv font32.sft magic.bin prvt.axf sprite.axf

/dev/nandb

Contains the u-boot boot parameters. The origin is showed below,

bootdelay=1

#default bootcmd, will change at runtime according to key press

bootcmd=run setargs_nand boot_normal#default nand boot

#kernel command arguments

console=ttyS0,115200

nand_root=/dev/system

mmc_root=/dev/mmcblk0p7

init=/init

loglevel=5

#set kernel cmdline if boot.img or recovery.img has no cmdline we will use this

setargs_nand=setenv bootargs console=${console} init=${init} loglevel=${loglevel}

setargs_mmc=setenv bootargs console=${console} init=${init} loglevel=${loglevel}

#nand command syntax: sunxi_flash read address partition_name read_bytes

#0x40007800 = 0x40008000(kernel entry) - 0x800(boot.img header 2k)

boot_normal=boota 40007800

#boot_normal=sunxi_flash read 40007800 boot;boota 40007800

boot_recovery=sunxi_flash read 40007800 recovery;boota 40007800

boot_fastboot=fastboot

#recovery key

recovery_key_value_max=0x13

recovery_key_value_min=0x10

#fastboot key

fastboot_key_value_max=0x8

fastboot_key_value_min=0x2

If you want to change your own kernel parameter, you can:

1. Save above text to a file, e.g. env.cfg

2. Use u_boot_env_gen tool to convert the file to a image



3. dd the image to /dev/nandb

If you are using Ubuntu 12.04 X86_64, there is a simple script help you do that

$wget http://dl.cubieboard.org/software/a20-common/mk_env_fex.tar

$tar -xf mk_env_fex.tar

$cd mk_env_fex

$vim env.cfg -- and change the content as you want

$./mk_env_fex.sh
