Hackable:1 on SheevaPlug

Testing hackable:1 on a usb device

Preparing the usb device

Needed:

• a serial terminal (minicom / cu / gtkterm / ...)
• a usb device ( => 500 Mo)

• get H1 version:

  # wget http://build.hackable1.org/Hackable1-Openmoko-Freerunner-user-rev5beta5.tar.gz
  

• mount the first partition of a formated usb device (ext3 works as well, here we mounted it in /mnt/usb and device was in /dev/sdb1):

  # mkdir /mnt/usb
  # mount /dev/sdb1 /mnt/usb
  

• untar tarball to the usb device:

  # tar xzpf Hackable1-Openmoko-Freerunner-user-rev5beta5.tar.gz -C /mnt/usb/
  

• edit inittab for serial:

  # echo "T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100" >> /mnt/usb/etc/inittab
  

• edit network configuration (we want eth0):

  # sed "s/^#auto eth0/auto eth0/;s/^#iface eth0/iface eth0/" -i /mnt/usb/etc/network/interfaces
  

• umount usb:

  # sync
  # umount /mnt/usb
  

Launch hackable:1 on the SheevaPlug

• turn on the SheevaPlug (or reboot it)
• start your serial terminal and press a key on it to get u-boot prompt Marvell>> (be fast if you just turned on the SheevaPlug)
• set temporary configuration for u-boot (for a permanent change, write saveenv after the validation of set bootargs):
  • on factory u-boot configuration:

    set bootargs 'console=ttyS0,115200 mtdparts=nand_mtd:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw root=/dev/sda1 rw rootdelay=10'
    boot
    

Install h:1 on flash

In this example we will explain how to upgrade the u-boot version of the SheevaPlug and at the same time install h:1 on flash.

For this example, we will use the h:1 rev5bet5 of the usb device described before and sheevaplug-installer-v1.0

You will need an x86 (or a chroot ..), libftdi1, php5-cli

Prepare files on your computer

• get hackable:1:

  $ wget http://build.hackable1.org/Hackable1-Openmoko-Freerunner-user-rev5beta5.tar.gz
  

• untar h:1 in a work directory:

  # tar xzpf Hackable1-Openmoko-Freerunner-user-rev5beta5.tar.gz -C workdir
  

• edit inittab for serial:

  # echo "T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100" >> workdir/etc/inittab
  

• edit network configuration (we want eth0):

  # sed "s/^#auto eth0/auto eth0/;s/^#iface eth0/iface eth0/" -i workdir/etc/network/interfaces
  

• edit filesystem (we want ubifs):

  # sed "s/rootfs/ubi0:rootfs/;s/jffs2/ubifs/;s/errors=remount-ro,//" -i workdir/etc/fstab
  

• download  the last SheevaPlug installer (c.f.:  here):

  # wget "http://www.plugcomputer.org/index.php/us/resources/downloads?func=download&id=53&chk=02a44f5d0d8a2944df16903b3d55d322&no_html=1"
  

• extract the tarball of sheevaplug-installer:

  # tar xzf sheevaplug-installer-v1.0.tar.gz 
  

• tar your h:1 in the work directory into a rootfs.tar.gz file which is in the installer directory of the sheevaplug-installer:

  # cd workdir
  # tar czpf ../sheevaplug-installer-v1.0/installer/rootfs.tar.gz *
  

Next .. usb device.

Prepare files on the usb device

Format a fat filesystem on the first partition of your usb device, then mount it and copy the root file-system / kernel / kernel modules / init ramdisk of the sheevaplug-installer installer directory on it and umount usb device (for this example the usb device will be at /dev/sdb1):

# mkfs.vfat /dev/sdb1
# mount /dev/sdb1 /mnt/usb
# cp ../sheevaplug-installer-v1.0/installer/{rootfs.tar.gz,uImage,modules.tar.gz,initrd} /mnt/usb
# sync
# umount /mnt/usb

flashing the Sheeva

• stop the countdown of u-boot to get the prompt of the SheevaPlug (see here for more information about how to do it),
• connect your usb device to the SheevaPlug,
• on your computer, go to the root directory of the sheevaplug-installer and run runme.php:

  # cd ../sheevaplug-installer-v1.0
  # php runme.php
  

• wait a while, then at the end of the execution of runme.php, look at your serial terminal. hackable:1 will be installed into the flash.
• look at the hackable1 login: and have fun.
