TODO: We need to remove generated SSH host certificates after we are done
This is work in progress. The goal is to automate as much as possible.
git clone git@github.com/parallella/pubuntu
export WORKSPACE=$(readlink -e parallella-ubuntu)
cd $WORKSPACE
For all commands issued on PC it is assumed that $WORKSPACE is the current working directory.
sudo gparted
- Create a 100 MiB FAT32 partition named 'BOOT'
- Create an 3700 MiB EXT4 partition named 'rootfs' (so the image fits in a 4GB SD card)
- Apply changes
- Set 'boot' flag for 'BOOT' partition. (Might not be necessary).

Reboot so we get sane time.
ssh linaro@linaro-nano.local
Copy skel files:
cp -r /etc/skel/. .
Logout and login again to get new environment:
exit
ssh linaro@linaro-nano.local
scp -r packages.basic.txt packages tests linaro@linaro-nano.local:~

This step is needed only if for some reason were unable to install the .deb packages in packages
[TODO]: Verify that this works
mkdir /var/tmp/builddeb

sudo apt-get build-dep libelf libelf-dev libevent libevent-dev libconfig libconfig-dev
sudo apt-get --build source libelf libevent libconfig
sudo dpkg -i $(ls *.deb | grep -v -- "-dbg_")
Copy over .deb packages. We can probably use them throughout the Linaro 14.** series without any problems.
cd ~
rm -rf /var/tmp/builddeb
###Install parallella opencl package This step is only necessary if there is a newer release than 1.6.0 available.
sudo rm -rf /usr/local/browndeer /etc/OpenCL/vendors/coprthr.icd
wget http://www.browndeertechnology.com/code/coprthr-1.6.X-parallella.tgz
tar -zxvf coprthr-1.6.0-parallella.tgz
sudo ./browndeer/scripts/install_coprthr_parallella.sh
rm -rf coprthr-1.6.0-parallella.tgz browndeer
### Add paths to .bashrc
echo 'export PATH=/usr/local/browndeer/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/browndeer/lib:/usr/local/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
### Add paths to root .bashrc
sudo su
echo 'export PATH=/usr/local/browndeer/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/browndeer/lib:/usr/local/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
### Add paths to .cshrc
echo 'setenv PATH /usr/local/bin:$PATH' >> ~/.cshrc
echo 'setenv LD_LIBRARY_PATH /usr/local/browndeer/lib:/usr/local/lib:$LD_LIBRARY_PATH' >> ~/.cshrc
[Longterm TODO: There's only 1.6 .deb source packages so install from source for now]
This is only necessary if a newer OpenMPI version than 1.8.3 is available
wget http://www.open-mpi.org/software/ompi/v1.8/downloads/openmpi-1.8.X.tar.gz
tar -zxvf openmpi-1.8.X.tar.gz
cd openmpi-1.8.X
./configure --prefix=~/usr \
--enable-mpirun-prefix-by-default \
--enable-static
make all
sudo make install
rm -rf openmpi*
Copy over to overlay
sync
shutdown -h now
Remove power.
[TODO] Don't we want same rootfs for everything? Easier maintenance. We could just disable X/LXDE autostart as final step in headless.
Insert micro-sd card into external host
sudo dd if=/dev/mmcblk0 of=<headless.img> bs=4M
####Copy over desktop package list from 2nd computer:
scp packages.desktop.txt linaro@linaro-nano.local:~
ssh linaro@linaro-nano.local:~
sudo apt-get install -y $(cat packages.desktop.txt | grep -v "^#" | sed 's,\s\s*,\n,g' | grep -v "^\s*$)

From Parallella:
sync
From regular computer:
sudo dd if=/dev/mmcblk0 of=my_backup.img bs=4M
Run zerofree to fill empty space with zeroes so compression of final image can work more efficient.
sudo zerofree my_backup.img
Insert a new micro SD card into regular computer
Option#1: Copying the whole image
sudo dd bs=64k if=my_backup.img of=/dev/mmcblk0
Option#2: Copying the rootfs directory structure to the current directory (works in reverse as well)
