Using The Correct Console Device

update the /etc/inittab file in the filesystem used for kernel

S:2345:respawn:/sbin/getty 115200 ttyS2
by,
S:2345:respawn:/sbin/getty 115200 ttyO2

Arago

Setting Up Build Environment and build

ubuntu install dependency

sudo apt-get install diffstat texi2html chrpath subversion python-psyco

Create the directory

Create a new directory for the build environment:

$ mkdir $HOME/oe
$ cd $HOME/oe

Clone Arago repositories

Now check out the following repositories:

$ git clone git://arago-project.org/git/arago.git
$ git clone git://arago-project.org/git/arago-oe-dev.git
$ git clone git://arago-project.org/git/arago-bitbake.git

The directory should now be populated with 3 subdirectories – arago, arago-oe-dev and arago-bitbake.

Copy setup/config files

Arago repository comes with samples of arago/setenv and arago/conf/local.conf files, which you can use as a starting point, by copying them into their actual names (without .sample extension) and modifying to suit your needs:

$ cp arago/setenv.sample arago/setenv
$ cp arago/conf/local.conf.sample arago/conf/local.conf

File: arago/setenv Edit arago/setenv file and make sure environment variables are set properly. OEBASE should point to the directory you’ve created in the beginning:

export OEBASE=$HOME/oe

File: arago/setenv Also, in order to use a separate "scratch" area outside of home directory, you may want to enable SCRATCH variable and point it appropriately:

export SCRATCH=/sim/scratch_AID

Set the environment variables

$ . arago/seten

Or,

$ source arago/setenv

Point to CSL toolchain

If not done before, set the PATH variable to point to the CodeSourcery toolchain (refer to Getting CodeSourcery Toolchain(The binary distribution for 2009q1-203 version) for obtaining one):

$ export PATH=/opt/arm-2009q1/bin:$PATH

Build a minimal base filesystem

Now it should be ready to start a build of the minimal filesystem image:

$ bitbake arago-base-image

Build a "demo" filesystem for OMAP3 EVM

$ MACHINE=omap3evm bitbake arago-console-image

Build different kernels for supported platforms

$ MACHINE=omap3evm bitbake virtual/kernel
$ MACHINE=beagleboard bitbake virtual/kernel
$ MACHINE=dm6446-evm bitbake virtual/kernel
$ MACHINE=dm355-evm bitbake virtual/kernel

High-level hierarchy of arago-deploy directory

Resulting images and packages will be placed under arago-deploy directory - images for the filesystem, kernel and bootloader; and ipk for binary IPK packages, respectively.

arago-deploy
|-- images
|   |-- arago
|   |-- dm355-evm
|   |-- dm6446-evm
|   `-- omap3evm
|-- ipk
|   |-- all
|   |-- arago
|   |-- armv5te
|   |-- armv7a
|   |-- dm355-evm
|   |-- dm6446-evm
|   |-- i686
|   |-- i686-armv5te-sdk
|   |-- i686-armv7a-sdk
|   `-- omap3evm
`-- sdk

Build individual package recipes

You can also look in oe/arago/recipes for individual package recipes that you can bitbake. For example:

bitbake curl
bitbake thhtpd

build a native compiler (on dm8168) using

MACHINE=c6a816x-evm ./arago-bitbake/bin/bitbake gcc-4.3.3(since codesourcery is using 4.3.3) or
MACHINE=c6a816x-evm ./arago-bitbake/bin/bitbake task-sdk-native

Build a File system

Setting up the build environment

setting up the build environment as Setting Up Build Environment

Configure the File system

File: /home/testbed/oe/arago/recipes/images

Use a existing file for a template

cp arago-base-tisdk-image.bb arago-base-sdr-image.bb

And modify it to:

#File: arago-base-sdr-image.bb
require arago-image.inc
#inherit tisdk-image

COMPATIBLE_MACHINE = "omap3|ti816x|dm365|omapl138|ti814x|omap4|ti33x"

how to

If one manually compiles libtool (bitbake libtool), then runs "bitbake guile", it compiles fine.

MACHINE=dm816x-evm bitbake libtool
MACHINE=dm816x-evm bitbake guile
MACHINE=dm816x-evm bitbake arago-base-sdr-image

FIXME: Modify the DEPENDS section of guile-native.inc

From
DEPENDS = "gmp-native" 

to something like 

DEPENDS = "gmp-native libtool" ?

Host and Target

After setting up opkg respository and pointing it to apache webserver with my vmware, now allows me easy install of python, dropbear, perl, etc cross-complied using code sourcery.

On Host:
Install Apache sudo apt-get install apache2
After you finish building packages on host, refresh the package index on the host: > bitbake package-index
add a symlink to the arago deploy/ipk directory to apache's home page /var/www/oe-repo

On EVM:
Determine your host IP address, and then add a src/gz line to /etc/opkg/opkg.conf
On the device, re-fetch the package list : opkg update
On the device, search for packages or install them
opkg list '*strace*'= =opkg install strace
