Technical Specifications

  • Freescale i.MX515 (ARM Cortex-A8 800MHz)
  • 512MB RAM
  • HDMI
  • 10/100Mbit/s Ethernet
  • 802.11 b/g/n WiFi

Running Fedora on a EFIKA MX Smarttop

This page will give you detailed instructions for running Fedora 17 GA on your EFIKA MX Smarttop. There are two images to choose from on the EFIKA MX Smarttop, choose the appropriate image for your target media - SD card or SATA/USB drive.

Download the image

The first step is to download the Fedora 17 image. The prebuilt images include kernels and can be written directly to a SD Card and booted without any additional steps or configuration. The image requires a minimum of 2GB and boots to a serial console.

Writing the Image

Linux Users

You can write the image to media of your choosing but it does have to meet the minimum size requirement of 2GB. Connect the media to your computer and make note of the drive. To write the image to your media run the following command, changing the drive to the location of your media.

For the SD Image:

Fedora-17-armhfp-mx51-mmcblk0.img.xz> /dev/<location-of-your-media>

Once completed run the below command to ensure the entire image is written to the device:


Windows Users

  • You will need to download Win32 Image Writer as well as a tool to extract the image such as 7-Zip.
  • Once downloaded and installed right click on the disk image and select "7-Zip->Extract files here"
  • Launch Win 32 Disk Imager and select the extracted disk image and the device you would like to write the files to. Click "Write". Be very careful during this step - all data on the selected drive will be lost!

Using Fedora on the EFIKA MX Smarttop

Connect the newly created media to your EFIKA MX Smarttop and power on. No further steps are required and your system should boot to a serial console log in prompt. If you do not have a serial cable to connect your Smarttop, you can watch your DHCP server for the newly connected device. After a few minutes you should be able to see the host "fedora-arm'. Use SSH to connect to the root account.

ssh root@fedora-arm (or IP)

The default root password is "fedoraarm". This should be changed immediately.

Known Issues

  • Yum requires the system time be correct for HTTPS to function. If yum updates are not working check your clock.
  • Genesi Efika MX SmartTop generates a kernel warning on reboot and requires use of the reset button to actually reboot.
  • The tar.xz rootfs archives do not preserve SELinux information or file capabilities. If you use these to create your own filesystem image it is recommended that you switch SELinux to use warnings instead of enforcing for first boot, then relabel and reinstall packages that rely upon filesystem capabilities such as glibc-common and ping.
  • Images are designed to be written to a minimum of 2GB SD cards. On first boot the partition will be resized to the maximum allowable amount. On the second boot the filesystem will be resized to fill the expanded partition. This works for SD cards, SATA Disks, and SSD drives.
  • Known release issues
