How To Give the Olimex A13-OLinuXino-MICRO a Static IP Address

If you’ve been following along, you should have a basic Debian Linux installation on your Olimex A13-OLinuXino-MICRO board and able to connect to WiFi. Make sure that the SSID and WPA password settings are correct in the /etc/wpa_supplicant/wpa_supplicant.conf file. See my guide on setting up WiFi with the A13-OLinuXino-MICRO and scroll down to the section on configuring wpa_supplicant.

Configure an SD Card Image for Better Compression

If you’re working on a Linux image for your single board computer (e.g. Raspberry Pi, OlinuXino, BeagleBone Black, etc.) and you notice that the compression of gzip sucks for the backup image, you need to re-format the SD card. For example, I created a Debian image on a card, which was partitioned for the whole 4GB. Now, we know that only the first few megabytes will be used, and the rest will be empty. However, if you’ve previously used the card (or you might see this with a factory-fresh card), the rest of the card will not be zeros. This will result in a poor compression ratio. My 4GB compressed to 3.1GB. Not great.

Install required packages

I like sudo, as it prevents me from doing stupid stuff. However, feel free to use “sudo su” if you don’t feel like typing “sudo” for half the commends. If you just copy and paste the commands, however, it really doesn’t matter.
