Hi all,
Based on some other images, I created a simple image relating debian and olpc. The other(below) relates olpc and indt.

This is the way that I use to update the OLPCs here in INdT. You need to use a pen drive and put the auto install files in your pen drive. I’m using the OLPC pen drive format. I don’t know if it’s necessary to auto reinstall, but I’m using this format and it’s working.

I formated the pen drive using the OLPC format(partition 1=primary, files ystem type=ext3,label=OLPCRoot). I wrote a tutorial about it already reported here.

cd /media/OLPCRoot/

sudo unzip /home/alecrim/kernel/olpc/olpc406_c11.zip

Archive: /home/alecrim/kernel/olpc/olpc406_c11.zip
creating: boot/
inflating: boot/q2c11.rom
inflating: boot/olpc.fth
inflating: boot/nand406.img
inflating: bzImage

Dismount the pen drive, plug it in the OLPC and turn it on. It’s going to auto install the new image. Be sure your OLPC is plug in the energy, it can not be interrupted during update.

Great success !!!!

OLPC uses a pen drive format to boot up the OS using the pen drive. This tutorial describe a way to format your pen drive and use the OLPC standard format. BE CAREFUL!!! You need to be sure about what you’re doing. Use the disk (/dev/sdb in my case) as parameter to fdisk. Dismount(umount /mount/point) all partitions of your pen drive.

sudo fdisk /dev/sdb

Inside fdisk you can see the menu options using m.

Command (m for help): m

Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition’s system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)

Delete the partitions already present. You will miss all data present in the pen drive.

After you partitioned the disk(pen drive), create the filesystem(mke2fs -j)

sudo mke2fs -j /dev/sdb1
mke2fs 1.40-WIP (14-Nov-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
128256 inodes, 256398 blocks
12819 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=264241152
8 block groups
32768 blocks per group, 32768 fragments per group
16032 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376

Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 28 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

Define a label to the partition. This name is going to be used during

sudo e2label /dev/sdb1 OLPCRoot

Unplug and plug the pen drive. It’s going to be automatically mount on /media/OLPCRoot .

Hi all,

With Antonios’s help and Allan’s idea, we test a Minimo with OLPC. It runs great !!!

PS: Tutorial soon !!!

Hi all,
I created a howto about debian in olpc and it’s published on http://wiki.debian.org/howto_debian_olpc . I’m with some problems and suggestions are welcome.

Solved:
- Mouse (working)

Problems:
- WLAN (not working)
- xserver-xorg-video-amd – driver “amd” (not working)

Thanks in advance !!!!
