Install Barrett System to a CF Card
WARNING: These instructions are not (yet) functional. DO NOT USE!
Install bootstrap system:
# Get the core system (on any Linux system) wget http://web.barrett.com/support/WAM_Installer/sysroot1204.tar.bz2 # Unzip it sudo tar xvjf sysroot1204.tar.bz2 -OR- # Use debootstrap (on an existing Ubuntu 12.04 system) sudo apt-get install debootstrap mkdir sysroot sudo debootstrap precise sysroot http://ubuntu.media.mit.edu/ubuntu sudo chroot sysroot apt-get clean exit sudo tar cvjf sysroot1204.tar.bz2 sysroot
Switch to the bootstrap system (chroot):
sudo chroot sysroot cd /dev MAKEDEV generic
Add packages:

Install Xenomai kernel:
# Get a tarfile of all preconfigured kernel sources and binaries wget http://web.barrett.com/support/WAM_Installer/ubuntu910xen252.tar.bz2 tar xvjf ubuntu910xen252.tar.bz2 rm ubuntu910xen252.tar.bz2 -OR- cd /usr/src # Get the base kernel wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.31.tar.bz2 # Get the Ubuntu 9.10 kernel patches wget http://web.barrett.com/support/WAM_Installer/linux_2.6.31-14.48.diff.gz # Get Xenomai wget http://download.gna.org/xenomai/stable/xenomai-2.5.2.tar.bz2 # Get the Barrett-modified Adeos patch to support Ubuntu's 2.6.31.4 instead of the default 2.6.31.8 wget http://web.barrett.com/support/WAM_Installer/adeos-ipipe-2.6.31.8-x86-2.4-09-barrett.patch # Unzip the kernel source tar xvjf linux-2.6.31.tar.bz2 # Make a handy link ln -sf linux-2.6.31 linux # Unzip the Xenomai sources tar xvjf xenomai-2.5.2.tar.bz2 # Make a handy link ln -sf xenomai-2.5.2 xenomai # Change to the linux source directory cd linux # Apply Ubuntu patches gunzip ../linux_2.6.31-14.48.diff.gz -c |patch -p1 # Apply Adeos patch patch -p1 < ../adeos-ipipe-2.6.31.8-x86-2.4-09-barrett.patch # Apply Xenomai patches ../xenomai-2.5.2/scripts/prepare-kernel.sh --linux=/usr/src/linux --arch=i686 # Grab the default Ubuntu kernel config to use as a starting point cp /boot/config-2.6.31-20-generic .config # Update the config with the newly-patched features (accept all defaults) yes "" |make oldconfig # Customize the kernel configuration make menuconfig General setup: Local version => -ipipe Processor type/features: no sparse IRQ, Processor family => Core2, no Enable -fstack-protector Power management: no ACPI Processor, no APM, no CPU Frequency scaling Device Drivers:Input Device:Misc: no PC speaker Real-time sub-system: add Shared interrupts, add Machine:SMI:Enable SMI, add Drivers:Serial:16550A, add Drivers:CAN:Philips:PEAK PCI Kernel hacking: no Kernel debugging # Build the kernel and associated driver modules make; make install; make modules_install # Create the initial ramdisk update-initramfs -c -k 2.6.31.4-ipipe # Save the config cp .config config-xenomai # Remove the object files to save space make mrproper
If you are installing this on a running system:
# Exit the chroot environment exit sudo umount sysroot/dev sudo umount sysroot/proc sudo umount sysroot/sys # Copy the new kernel, related modules, and source sudo cp sysroot/boot/*ipipe /boot sudo cp -a sysroot/lib/modules/2.6.31.4-ipipe /lib/modules sudo cp -a sysroot/usr/src/* /usr/src # Create a group for users allowed to execute realtime tasks sudo addgroup xenomai (take note of the group ID assigned) # Add yourself to the xenomai group sudo usermod -aG xenomai <username> # Update your bootloader with the new kernel and initrd # The steps required depend on your system # Just make sure to append the kernel option "xeno_nucleus.xenomai_gid=1001" # If your "xenomai" group has a different group ID, use it here # Reboot, then skip down to "Compile and test Xenomai runtime"
If this is a new install to be copied to a fresh disk, set up initial environment:
# Add the 'robot' user adduser robot password = WAM addgroup xenomai addgroup admin echo '%admin ALL=(ALL) ALL' >> /etc/sudoers usermod -G adm,cdrom,audio,video,plugdev,admin,xenomai robot # Set the host name echo 'WAM' > /etc/hostname # Set the localhost entry echo '127.0.0.1 localhost WAM' > /etc/hosts # Set up the time zone echo 'America/New_York' > /etc/timezone dpkg-reconfigure -f noninteractive tzdata # Clear the apt package cache apt-get clean # Get the file system table wget http://web.barrett.com/support/WAM_Installer/fstabAtom -O /etc/fstab # Get the network interface config file wget http://web.barrett.com/support/WAM_Installer/interfacesAtom -O /etc/network/interfaces # Get the modules file wget http://web.barrett.com/support/WAM_Installer/modulesAtom -O /etc/modules # Get the rc.local file wget http://web.barrett.com/support/WAM_Installer/rcAtom -O /etc/rc.local # wget /etc/conky/conky.conf exit sudo umount sysroot/dev sudo umount sysroot/proc sudo umount sysroot/sys
Format new disk (use the 9.10 install CD if your parted does not support ext4):
umount /media/<mountpoint> sudo parted /dev/sdb (or wherever the new disk is) print (make sure this is the device you want to use) mklabel msdos mkpart primary ext2 0 64 mkpart primary ext4 64 8192 set 1 boot on quit sudo mkfs.ext2 /dev/sdb1 (or wherever the first new partition is) sudo mkfs.ext4 /dev/sdb2 (or wherever the second new partition is)
Copy system to new disk:
sudo mount /dev/sdb2 /media/sdb2 sudo mkdir /media/sdb2/boot sudo mount /dev/sdb1 /media/sdb2/boot sudo cp -av sysroot/* /media/sdb2
Install bootloader:
sudo mount --bind /dev /media/sdb2/dev sudo mount --bind /proc /media/sdb2/proc sudo mount --bind /sys /media/sdb2/sys sudo chroot /media/sdb2 cp /usr/lib/grub/i386-pc/* /boot/grub wget http://web.barrett.com/support/WAM_Installer/menu.lstAtom -O /boot/grub/menu.lst grub find /grub/grubenv root (hd1,0) setup (hd1) quit # Erase unused sectors (for better drive image compression) # Takes up to 30 minutes. Only do this if you plan on imaging the drive. dd if=/dev/zero of=delme bs=8M; rm delme # Exit the chroot environment and unmount everything exit sudo umount /media/sdb2/dev sudo umount /media/sdb2/proc sudo umount /media/sdb2/sys sudo umount /media/sdb2/boot sudo umount /media/sdb2
Boot into new system

Not for CF
Shut down the target PC
sudo shutdown -h now
!!! DONE !!!
Installing fsarchiver
sudo add-apt-repository ppa:randomaction/ppa sudo apt-get update sudo apt-get install fsarchiver
Make filesystem images using fsarchiver
# Unmount the new drive sudo umount /media/* time sudo fsarchiver -v -z 7 -L "Kernel 2.6.31.4-ipipe, P3, no EDID" savefs wamBoot.fsa /dev/sdb1 time sudo fsarchiver -v -z 7 -L "Ubuntu 9.10, Xenomai 2.5.2, SocketCAN" savefs wamRoot.fsa /dev/sdb2
Restore filesystem images to a new disk using fsarchiver
# Unmount the new drive sudo umount /media/* # Use parted to partition the disk sudo parted -s /dev/sdb mklabel msdos sudo parted -s /dev/sdb mkpart primary 0 64 sudo parted -s /dev/sdb mkpart primary 64 8192 sudo parted -s /dev/sdb set 1 boot on # Restore the filesystem images time sudo fsarchiver -v restfs wamBoot.fsa id=0,dest=/dev/sdb1 time sudo fsarchiver -v restfs wamRoot.fsa id=0,dest=/dev/sdb2 # Mount the new system sudo mount /dev/sdb2 /media/sdb2 sudo mkdir /media/sdb2/boot sudo mount /dev/sdb1 /media/sdb2/boot # Install the bootloader sudo grub-install --root-directory=/media/sdb2/ hd1 # Unmount sudo umount /media/sdb2/boot sudo umount /media/sdb2
Make a disk image using dd
# Read from the CompactFlash # Takes about 30 min for an 8GB CF disk, be patient sudo dd if=/dev/sdb bs=1k |gzip >cf.img.gz
Restore a disk image to a new disk using dd
# Write to the CompactFlash # Can take >> 30 min for an 8GB CF disk, be patient zcat cf.img.gz | sudo dd of=/dev/sdb bs=1k
Shrink an ext2 filesystem to its minimum size:
tune2fs -O ^has_journal /dev/sda1 (dash cap oh) (ext3->ext2, delete journal) fsck.ext2 -f /dev/sda1 (check filesystem) resize2fs -M /dev/sda1 (shrink filesystem)
Take note of the output from resize2fs above. It is listed in 4k blocks. But fdisk expects sizes to be specified in 1k blocks, so when you resize the partition, take the above number and multiply by 4.03 (absolute minimum, no room to grow).
Shrink the partition (for efficient imaging):
fdisk /dev/sda d <delete existing> n <new primary> 1, start cyl = 1, size = +x (calculated above) a <make it bootable> 1 w <write the new partition table> q <quit>
