* Summary [#p1c3acca]
>
The whole section is revised for explaining the installation process of Open Embedded Linux on bc10, including~
X-Loader and U-Boot. The previous version was discussed only the configuration of OpenEmbedded, a Linux~
framework for embedded systems. However, in new version, the installation process of the Angstrom Distribution~
is described. (The Angstrom Distribution is treated as one of Linux distributions for embedded system since it~
requires sufficient amount of knowledges of OpenEmbedded as well as embedded Linux and call it “OpenEmbedded Linux.")~
~
COLOR(red){(Caution)From November 2010, the built system, which is argued here, has been greatly modified. On stable/2009 branch,}~
COLOR(red){the build process is unlikely completed. On Master branch, the build process can be finished, the directories of userland}~
COLOR(red){and version of software can be different from the ones described here}~
~
For the details, please visit [[Building Angstrom>http://www.angstrom-distribution.org/building-angstrom]].
* How to create the Build Environment of OpenEmbedded for bc10 [#eded136e]
>
To follow the explanation listed at '''[[Building Angstrom:http://www.angstrom-distribution.org/building-angstrom]]''' on the Angstrom Distribution, configure the build environment~
in Ubuntu 10.04.~
** Ubuntu 10.04 development environment [#xaf656a7]
>
- Configuration and addition of packages~
>
As the default, '''dash''' is the shell script for Ubuntu. However, this causes unexpected errors when BitBake is executed since~
'''bash''' is used in some parts of BitBake.
To use the command shown below, change the shell script of Ubuntu form '''dash''' to '''bash'''.
$ sudo dpkg-reconfigure dash
As execute the command, it will ask whether dash is installed into '''/bin/sh''' or not. and, select ''No'' as the answer. Then, '''bash'''~
is chosen for shell script.~
>
To follow the direction published at the [[Debian section:http://wiki.openembedded.org/index.php/OEandYourDistro#Debian]] of [[OEandYourDistro:http://wiki.openembedded.org/index.php/OEandYourDistro]], install '''deb packages'''. The packages are mandatory~
and necessary for build.~
$ sudo apt-get install ssh
>
$ sudo apt-get install sed wget cvs subversion git-core \
coreutils unzip texi2html texinfo libsdl1.2-dev docbook-utils \
gawk python-pysqlite2 diffstat help2man make gcc build-essential g++ \
desktop-file-utils chrpath
>
$ sudo apt-get install libxml2-utils xmlto python-psyco docbook
>
-gzip~
>
As BitBake base-image is executed in Ubuntu 10.04, [[DATA-CAC Error:http://groups.google.co.jp/group/beagleboard/browse_thread/thread/2cbddf944f98dfdc]] occurs at '''expat-2.0.1.tar.gz'''. This error is due to~
'''[[gzip 1.3.12:http://groups.google.co.jp/group/beagleboard/browse_thread/thread/2cbddf944f98dfdc]]'''. This '''gzip 1.3.12''' is obsolete and needed to be updated. '''gzip 1.3.12 ''' is [[replaced with '''gzip1.4''':http://maltanar.blogspot.com/2010/05/getting-working-gzip.html]].~
>
Check up the version of gzip~
$ gzip --version
gzip 1.3.12
As it is shown above, the version of gzip is 1.3.12, so it is going to be updated to 1.4. Obtain '''gzip1.4''' from '''gnu.org''',~
and build and install it.~
$ wget ftp://ftp.gnu.org/gnu/gzip/gzip-1.4.tar.gz
$ tar xvfz gzip-1.4.tar.gz
$ cd gzip-1.4
$ ./configure
$ make
$ sudo make install
After complete the installation, re-examine the version of gzip.~
$ gzip --version
gzip 1.4
** Build BitBake environment [#x0a6ecd8]
>
This explains how to set up the BitBake environment. This mostly follows the instructions published at Building Angstrom,~
yet the instructions are slightly altered for bc10.~
-What is '''BitBake'''
>
BitBake acts like '''make''' command as a tool, and it specifically manages kernel and packages for embedded Linux distributions.~
Its package management system is called '''recipe'''. A '''recipe''' informs BitBake all steps of the installation of packages, and a '''recipe'''~
maintains a meta data for the information, which is needed to install the packages. For the details, please look at "[[BitBake User Manual:http://docs.openembedded.org/bitbake/html/]]".~
-angstrom-setup-scripts~
>
For building Angstrom (OpenEmbedded Linux), angstrom-setup -script is used for saving configuration scripts and the files,~
which are created after executing scripts, and building.~
>
Obtain angstrom-setup-script by git.~
$ cd ~
$ git clone git://gitorious.org/angstrom/angstrom-setup-scripts.git
$ cd angstrom-setup-scripts
To run '''oebb.sh''' enter the name of the targeted machine. It will beagleboard to be exact.~
$ ./oebb.sh config beagleboard
After executing, receive the message shown below.~
There now is a sourceable script in ~/.oe/enviroment. You can do '.
~/.oe/environment' and run 'bitbake something' without using ./oebb.sh
as wrapper
Setup for beagleboard completed
Execute '''oebb.sh update''', and download OE and BitBake files.~
$ ./oebb.sh update
At the end of the execution, the error massage appears, but this is ''not'' affect the update process and build process.~

-mmap_min_addr
>
While BitBake is executed, a build error occurs at build of '''qemu-arm'''. Preventing this error, the value of '''vm/mmap_min_addr'''~
is set to 0. Although [[wiki:http://wiki.openembedded.org/index.php/OEandYourDistro#Using_OpenEmbedded_on_Linux_systems]] notes that value of 128 is acceptable, the error will be persist, and the error message shown below~
appears as BitBake is executed.~
$ MACHINE=beagleboard bitbake base-image
FATAL: Openembedded's config sanity checker detected a potential
misconfiguration.
Either fix the cause of this error or at your own risk disable the
checker (see sanity.conf).
Following is the list of potential problems / advisories:
/proc/sys/vm/mmap_min_addr is not 0. This will cause problems with qemu so please fix the value (as root).
To fix this in later reboots, set vm.mmap_min_addr = 0 in /etc/sysctl.conf.
There are two ways to configure the value of '''mmap_min_addr''' is equal to 0. [SOLVED - update 2010] of [[wiki:http://wiki.openembedded.org/index.php/OEandYourDistro#Using_OpenEmbedded_on_Linux_systems]] shows two different~
methods ( '''a)''', '''b)''' ) to change the value of '''mmap_min_addr''' to 0. (In wiki, the value is set to be 128, but the error message will~
appear as BitBake is executed.)~

- about bitbake base-image and bitbake console-image
>
base-image handles the same tasks as its predecessor, '''nano''', and it installs kernel, busybox, and ipkg. Console-image is add~
extra features to its previous version, '''task-base'''. The newly added features are packages for several peripherals, Bluetooth,~
and WiFi.

$ git checkout -t -b bc10 origin/bc10
$ make omap3530bc10_config
$ make
After its build is completed, '''x-load.bin''' is created.
- Adjust the binary image~
>
The format of '''x-load.bin''' does not fit into the configurations of OMAP BootROM. As '''x-load.bin''' is read into NAND Flash or SD~
card without any modification, it does not work as a bootloader. Fixing this issue, '''x-load.bin''' is needed to be altered by~
'''signGP'''. The executable file of '''signGP''' is downloaded form [[here:http://beagleboard.googlecode.com/files/signGP]].~
~
'''signGP''' can be applied as it is defined below.
$ ./signGP x-load.bin
'''x-load.bin.ift''' is created after applying '''signGP'''.~
Due to the specification of BootROM, '''x-load.bin.ift''' is saved as '''MLO''' when it is copied and saved in the root directory of~
the SD card.
* Place created image files in SD card (1) [#s3bc9746]
>
Some created files, which are required for booting bc10, are copied to a SD card. Read“[[Create bootable SD Card:http://labs.beatcraft.com/en/index.php?bc10%2Fbooting#mef5758b]]” section of [[bc10/booting]],~
create FAT32 and Linux partitions in the SD card.~
(Hereafter FAT32 partition and Linux partition are named and called LAVBEL1 and LABEL2, respectively.)~
~
As the intended OS, which is booted from U-Boot, is a Linux, this is how files should be placed and organized inside the SD card.~
- FAT32 partition
-- X-Loader
-- U-Boot
-- Linux kernel
-- boot.scr
- Linux partition
-- Linux root file system
** FAT32 partition [#o1686f4c]
>
- X-Loader~
>
As X-Loader, the first bootloader, is placed on SD card, there are several restrictions on the method of placing it. Please follow the~
instructions written below.~
+ After formatting FAT32 partition, '''x-loader''' is the first to be placed.
+ It will be put on the top directory of FAT32 partition.
+ Change the name from '''x-loader''' to '''MLO'''.

Under the same directory, in which '''u-boot-beagleboard.bin''' is found, there is '''uImage-beagleboard.bin''' , and its name is~
changed to '''uImage''' and copied to FAT32 partition.
$ cp uImage-beagleboard.bin /media/LABEL1/uImage

configures in the serial console of the u-boot's command prompt. This setting significantly reduces the time since it does not~
require the configuration as each time X-Loader is booted. This is also configured for not changing memory mapping. To follow~
the instructions, create '''boot.script'''.~
