Updating the Edison Firmware

Most Edisons will ship with an older firmware (perhaps many months out of date). They will either contain bugs or simply not work with the latest version of the XDK IoT Edition. To remedy this problem, we highly recommend updating the firmware on the Edison.

To begin, download the latest firmware. Navigate to Intel’s site using the link below and click to download the Latest Yocto Poky image for Edison.

Once the download is complete, locate the file on your computer, and unzip it.

NOTE: If you did not install the XDK or do not wish to use the Phone Flash Tool Lite to update your Edison, you may try the Manual Firmware Update method in Appendix D.

Updating the Firmware with the Phone Flash Tool

If it is not open already, open the Intel® Phone Flash Tool Lite program that we installed in the last section.

Click Browse, and navigate to the unzipped Edison firmware directory. Locate the FlashEdison.json file, and click Open. This will load the firmware into the Phone Flash Tool.

Click the Start to flash button. The Phone Flash Tool will tell you to plug in your Edison. Plug the USB micro cable into the OTG Port on the Base Block, and plug the other end into an open USB port of your computer.

The Phone Flash Tool should begin to flash the Edison with a new firmware image.

Flashing the Edison's firmware

The updating process can take anywhere from 5-10 minutes. We recommend making a sandwich and catching up on web comics in that time. The Edison will restart once or twice after the installation is complete. Wait at least 2 more minutes after the update to allow the Edison to finish rebooting. Do not unplug the Edison in that time!

That’s it! You should see a “Flash success” message in the Phone Flash Tool. If this worked, you can close the Phone Flash Tool Lite, and move on to the next section.

Successful firmware update in the Edison

NOTE: If the Edison failed to flash, try the process again from the beginning. Close the Flash Tool Lite and unplug the Edison. Start the Flash Tool Lite again. This might take a few tries. If that still does not work, try the Manual Firmware Update method.
