Duovero Setup

Many instructions here are mirrored from Toby Schneider's instructions at http://gobysoft.org/wiki/InstallOnGumstixOvero.  

Root filesystem preparation

Follow these steps to create a debian wheezy root filesystem.  In this section we will use # host to indicate commands run on the host machine, and # chroot for commands commands run inside the chroot filesystem.  

1. Install dependencies:

   # host
   sudo apt-get install multistrap qemu-user-static

2. Pick a working folder, in this case ~/duovero
 

3. Create a directory to hold the root filesystem:

   # host
   cd ~/duovero
   mkdir rootfs

4. Create a configuration file debian.conf in ~/duovero and paste in the following.  Additional packages can be included here or installed later using apt-get.  

   [General]
   arch=armel
   directory=~/duovero/rootfs
   retainsources=~/duovero/sources
   cleanup=true
   noauth=true
   unpack=true
   bootstrap=Wheezy Net Utils
   aptsources=Wheezy
   
   [Wheezy]
   packages=apt locales udev adduser sudo nano build-essential less
   source=http://debian.lcs.mit.edu/debian
   suite=wheezy
   
   [Net]
   packages=netbase ifupdown iproute net-tools iputils-ping ntp
   source=http://debian.lcs.mit.edu/debian
   
   [Utils]
   packages=wget
   source=http://debian.lcs.mit.edu/debian

5. Run multistrap to create the root filesystem.  

   # host
   multistrap -a armel -d ~/duovero/rootfs -f debian.conf

6. Copy the QEMU ARM emulator into the new root filesystem so it is on the path when we chroot in.  

   # host
   sudo cp /usr/bin/qemu-arm-static ~/duovero/rootfs/usb/bin/

7. (Optional) If you need /dev/random (for installing openssh-server for example), mount /dev in the chroot.  

   # host
   sudo mount -o bind /dev ~/gumstix/rootfs/dev

8. Chroot into the new filesystem.  

   # host
   sudo chroot ~/duovero/rootfs /bin/bash

9. Finish setting up packages 

   # chroot
   dpkg --configure -a

   Answer "no" when prompted to use "dash" as "/bin/sh".  If any packages fail to configure (possibly ifupdown), just run dpkg again.  

10. Set the root user password.

    # chroot
    passwd

11. (Optional) Add a new user and give it sudo permissions 

    # chroot
    adduser mit
    printf "mit     ALL=(ALL) ALL" >> /etc/sudoers

12. Configure locales.  Choose 136 for en_US.UTF-8.  

    # chroot
    dpkg-reconfigure locales

13. Add a DNS server 

    # chroot
    printf "nameserver 8.8.8.8" > /etc/resolv.conf

14. Add a static network entry for eth0 (install the isc-dhcp-client package for dhcp support) 

    # chroot
    nano /etc/network/interfaces
     
    auto eth0
    iface eth0 inet static
    address 192.168.1.102
    netmask 255.255.255.0
    gateway 192.168.1.1

15. Restart networking to apply the new interface. 

    # chroot
    /etc/init.d/networking restart

    This might yield an error, but try pinging something anyways and it should work.  
     

16. Update the apt repositories 

    # chroot
    apt-get update

17. Assign a hostname and update the hosts file 

    # chroot
    printf "nostromo" > /etc/hostname
    printf "127.0.0.1   nostromo\n" >> /etc/hosts

18. Add the serial console (specific to gumstix overo and duovero) 

    # chroot
    printf "T0:2345:respawn:/sbin/getty -L 115200 ttyO2 vt102\n" >> /etc/inittab

19. Add a proc filesystem to fstab 

    # chroot
    nano /etc/fstab
     
    # /etc/fstab: static file system information.
    #
    # <file system> <mount point>   <type>  <options>       <dump>  <pass>
    proc            /proc           proc    defaults        0       0
