* A computer with Linux, MacosX or Windows * A Raspberry pi, Model B * An SD Card, We recommend an 2GB class 4 SD card * Download the latest official calaos image for raspberrypi :http://calaos.fr/download/experimental/calaos-image-raspberrypi-2014-04-28.tar.xz

Launch a terminal and go in the directory where you download the calaos os image. $ cd ~/Downloads $ tar xvf calaos-image-raspberrypi-2014-04-28.tar.xz Insert the sdcard into the sdcard reader of your PC. You need to know what's the device created by linux when the card is inserted. The device name is something like /dev/sdX or /dev/mmcblkX. To know the exact name use the following command : $ dmesg | tail

You should get something like that : [191385.790344] mmc0: new high speed SDHC card at address 1234 [191385.790574] mmcblk0: mmc0:1234 SA04G 3.67 GiB [191385.791564] mmcblk0: p1 p2 In that case the device is /dev/mmvblk0

We need to ensure that this device is not mounted on your system $ sudo unmount /dev/mmvblk0p1 $ sudo unmount /dev/mmvblk0p2 … or in case your device is detected as /dev/sdX $ sudo unmount /dev/sdd1 $ sudo unmount /dev/sdd2 … You can verify that the devices are not mounted by using the mount command $ mount No sdcard must appears in the resulting list.

Let's now copy the calaos os on the sdcard sudo dd if=calaos-image-raspberrypi-2014-04-28.sdimg of=/dev/mmcblk0 Once the operation is terminated, you can remove the sdcard, and insert it in the Raspberry pi.
