Compiling Angstrom for pico-SAM9G45

Compile using the new meta-angstrom distribution based on meta-openembedded branch (new branch)

 git clone git://github.com/Angstrom-distribution/setup-scripts.git -b angstrom-v2012.05-yocto1.2
 cd setup-scripts/sources
 git clone git://gitorious.org/picopc-tools/meta-picosam9.git
 cd ..
 echo 'EXTRALAYERS="${TOPDIR}/sources/meta-picosam9"' >> conf/bblayers.conf
 MACHINE=picosam9 ./oebb.sh config picosam9

Start building

If you want to build only the kernel:

 MACHINE=picosam9 ./oebb.sh bitbake virtual/kernel

or if you want a small base image:

 MACHINE=picosam9 ./oebb.sh bitbake console-image

Compile using the classic angstrom distribution based on openembedded.dev branch (old branch)

This is obsolete and kept for reference. All development and maintenance are done on the new meta-angstrom.

 git clone git://gitorious.org/picopc-tools/picopc-angstrom-setup.git
 cd picopc-angstrom-setup
 MACHINE=picosam9 ./oebb.sh update
 MACHINE=picosam9 ./oebb.sh config picosam9

The script will also download and install picosam9 recipes for angstrom from here: https://gitorious.org/picopc-tools/picopc-angstrom

To get the same build as the binary ones provided by mini-box.com you can use (note: this recipes only work on old openembedded.dev branch NOT the new meta-angstrom):

 MACHINE=picosam9 ./oebb.sh bitbake picosam9-gpe-image
 MACHINE=picosam9 ./oebb.sh bitbake picosam9-console-image

Notes

• The build process builds kernel and a rootfs, you will still need to copy those file to a microSD respecting the info here: http://arm.mini-box.com/index.php?title=Main_Page#Building_an_image_from_scratch

• The BOOT.BIN bootstrap is not built by angstrom. You can get a binary from:http://resources.mini-box.com/online/pico-SAM9G45/android/BOOT.BIN or compile your own version.

• Latest version that our classic angstrom build (openembedded.dev) has been tested is: tested_2011-01-13. Other versions might have a different behavior. You can get this version by doing:

  cd sources/openembedded
  git checkout tested_2011-01-13 -b tested_2011-01-13

• The version of bitbake used is:

  cd sources/bitbake
  git checkout 1.12

• All above commands from step #2 downward must be issued from the picopc-angstrom-setup/ folder.
