This post exists because, as far as I can tell, a tutorial for Debian on gumstix using multistrap does not exist. With that being said, this post is sloppy and to the point, and I am happy with that.
I am not going to bother telling you which packages to install, if you have read this far into the post you are capable of figuring this out on your own.
Pick a directory to work out of, inside that directory, create a file called emdebian.conf and make it look like this:
debootstrap=Grip Networking Debian Misc
packages=ntpdate udev lrzsz netcat adduser sudo nano
packages=apache2 php5 gpsd gpsd-clients python locales wget lynx openssh-server
packages=netbase ifupdown iproute net-tools iputils-ping
The above file is fairly self explanatory, if you would like to read more about it:
Make a destination directory for your new rootfs,
And now execute the multistrap command:
sudo multistrap -a armel -d EmDebian/ -f emdebian.conf
This will built in about 5 minutes depending on your internet connection and processing power. Once finished copy over the emulator so we can actually chroot into the system:
sudo cp /usr/bin/qemu-arm-static EmDebian/usr/bin/
Chroot into the system:
sudo chroot EmDebian/
And finalize the installation by executing dpkg,
dpkg --configure -a
While in this environment we should do some basic tasks to make the system functional. Lets add a user:
Add the user to the /etc/sudoers, such as:
mba ALL=(ALL) ALL
We should probably add some networking functionality by adding the following to /etc/network/interfaces:
#iface eth0 inet dhcp
iface eth0 inet static
and then add the following to /etc/resolv.conf
Create /etc/fstab with the following:
# /etc/fstab: static file system information.
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
Add a hostname to /etc/hostname. Then add that to /etc/hosts.
The final task inside the chroot environment is to enable the serial console. Edit /etc/inittab and add the following line in the appropriate place:
T0:2345:respawn:/sbin/getty -L 115200 ttyS2 vt102
Incidentally, if you are following this tutorial to install Ubuntu, head over to Short and Sweet with the link provided above to properly enable the serial console.
This finalizes the work that needs to be performed in the chroot environment. Exit out of the chroot:
Now comes the time to tar up our rootfs for safe keeping, cd into the install directory i.e.
and execute your favorite tar command
sudo tar -czf ../EmDebian.tar.gz *
While that compresses it is time to prepare the SD card. Be sure to unmount it if it mounted automatically, otherwise you might be sorry. There is a correct way to format this card, according to the gumstix wiki and the Short and Sweet blog but I do not care for the long and irritating process. If you would like to do it the correct way, head over there, otherwise we will do it the easy way, save about 10 minutes worth of suffering and only waste a fraction of space on the sdcard. Start off with executing cfdisk:
sudo cfdisk -z /dev/mmcblk0
Make two partitions on the SD card, a 64MB primary that is of type 0C and a second partion with the remainder of the space, type 83. The partition table should look like this:
cfdisk (util-linux-ng 2.17.2)
Disk Drive: /dev/mmcblk0
Size: 3959422976 bytes, 3959 MB
Heads: 4 Sectors per Track: 16 Cylinders: 120832
Name Flags Part Type FS Type [Label] Size (MB)
mmcblk0p1 Boot Primary W95 FAT32 (LBA) 64.00
mmcblk0p2 Primary Linux 3895.43
Format this first partition:
sudo mkfs.vfat -F 32 /dev/mmcblk0p1 -n FAT
And then the second:
sudo mkfs.ext3 /dev/mmcblk0p2
This concludes the sd card formatting procedure. Now comes the time to add our kernel and supporting images as well as our rootfs to the card.
Mount the two sd partitions to a location on your system, I use the following:
sudo mount /dev/mmcblk0p1 /mnt/SD1
sudo mount /dev/mmcblk0p2 /mnt/SD2
Our first task will be to copy the required binaries to the boot partition. Search Google for these or check out Short and Sweet, I built my own images to include some kernel code that is not present in the images available from gumstix. Copy these files onto the sd card in the following order, rumor has it that this is important.
sudo cp MLO-overo /mnt/SD1/MLO
sudo cp u-boot-overo.bin /mnt/SD1/u-boot.bin
sudo cp uImage-overo.bin /mnt/SD1/uImage
If you built modules, copy those over to the sd card as well:
sudo cp modules-2.6.34-r90-overo.tgz /mnt/SD2/
And move the tar file over to the sd card:
sudo cp EmDebian.tar.gz /mnt/SD2
Extract it onto the sd card:
sudo tar zxf EmDebian.tar.gz
and now the modules:
sudo tar zxf modules-2.6.34-r90-overo.tgz
Do not extract into the root of your current system. That completes the install. Unmount the sd card and place it in the overo board. Launch minicom so we can watch the boot procedure and then login to our system.
minicom -o -D /dev/ttyUSB0 -b 115200
If I remember correctly there are some other options that need to be set to get minicom to work correctly, something about turning flow control off... search google.
And there we have it, a successful boot:
Debian GNU/Linux 6.0 DataAqDebian1 ttyS2
A couple of tasks remain:
sudo dpkg --configure -a
And lets make sure it is on the network:
mba@EmDebian:~$ ping google.com
PING google.com (184.108.40.206) 56(84) bytes of data.
64 bytes from qw-in-f147.1e100.net (220.127.116.11): icmp_req=1 ttl=52 time=31.9 ms
And we are done here.
