Building linux for atngw100 from OE (open embedded)

You may ask why open embedded when u have buildroot. The thing is that open embedded has lots of packages that u can build. As far i know they added avr32 arch support recently.
U can get started from http://wiki.openembedded.net/index.php/Getting_Started.

My local.conf is
----------------------------------------------------------------------------------------------------------------------------------------------------------
DL_DIR = "/home/vijay/stuff/embeddedlinux/OE/stuff/sources"
BBFILES := "/home/vijay/stuff/embeddedlinux/OE/stuff/org.openembedded.dev/packages/*/*.bb"
MACHINE = "atngw100"
TARGET_OS = "linux-uclibc"
DISTRO = "angstrom-2008.1"
IMAGE_FSTYPES = "jffs2 tar ext2 ext3"
ANGSTROM_MODE = "uclibc"
PREFERRED_VERSION_uclibc ?= "0.9.29"
PREFERRED_VERSION_uclibc-initial ?= "0.9.29"
----------------------------------------------------------------------------------------------------------------------------------------------------------
I cracked my head to findout that i need to add ANGSTROM_MODE = "uclibc" and PREFERRED_VERSION_uclibc ?= "0.9.29" options ....... huh ... modify the above file to ur system convenience.

now u cam build a minimal-image for atngw100 by
bitbake minimal-image

u can have a look at org.openembedded.dev/packages/images folder for wht images u can build and org.openembedded.dev/packages for the list of packages/applications that OE can build.

Building linux for atngw100 from buildroot

You can build linux system for ur atngw100 easily by using buildroot. There are many suppliers for buildroot
1) Atmel beta release (http://www.atmel.no/buildroot/)
2) From buildroot site (http://buildroot.uclibc.org/)
3) Some guy (http://code.google.com/p/buildroot/) mentioned in http://avr32linux.org/twiki/bin/view/Main/DevelopmentTools
I have build my system from the 3rd buildroot.
svn checkout http://buildroot.googlecode.com/svn/trunk/ buildroot-avr32

make atngw100_defconfig
make menuconfig
make

u can also use atngw100_expanded_defconfig or atngw100-base_defconfig instead of atngw100_defconfig; these add more options like lcd driver,keyboard driver, mouse driver, X-windows etc ...... if u have one attached to ur atngw100. have a look at this "buildroot-avr32/target/device/Atmel" folder; there u will find for what all devices u can build the buildroot.

I have few problems while building for atngw100_expanded_defconfig, but fortunately they were easy to solve. :D.

PS: Im yet to get my board, i was just playing around with buildroot and OE till i comes.

Cheapest evaluation board that support embedded linux (ATNGW100)

I have been searching for a evaluation board that support embedded linux; The ATNGW100 from atmel is the cheapest i could find around.Its based on avr32 - AP7000 microcontroller . Its around $80. You can build linux system and applications for this board either by buildroot or OE (open embedded). only draw back that i could say is that this doesn't have a usb host (AP7000 microcontroller); Other than that its pretty good for $80(Rs 4000). Atmel is gonna release AP720* series which has support for usb host around end of 2008 . Long time for me ,cant wait . Planning to get one of these soon :D

Psp Linux toolchain

here is my buildroot environment i compiled for psp using instructions from http://jacksonm80.googlepages.com/linuxonpsp.htm
extract it to /usr/src and add mipsel-linux-gcc to PATH variable
