Appendix D: Manually Updating the Firmware

If the Phone Flash Tool was not working properly or you did not want to use the Phone Flash Tool, you can try to flash the Edison manually.

NOTE: These steps are more involved and requires some familiarity with the command line. If you run into issues, check in Appendix A: Troubleshooting first before posting a question in the Comments section.

Find your operating system below and follow the directions. Note that you will need to use the USB OTG port of the Edison.

Edison Base Block USB OTG port

Windows

Navigate to the unzipped directory of the downloaded Yocto image. Look for the file flashall.bat.

Edison Yocto image flashall scripts

Double-click flashall.bat. That should bring up a window asking you to plug in your Edison.

Flashall asking to plug in the Edison

Plug the USB micro cable into the OTG Port of the Edison, and plug the other end into an open USB port of your computer. Wait a few moments, and the script will begin flashing the Edison.

Wait while the Edison is flashed

You will either get a notice that the flashing process is complete or the window will close. Wait at least 2 more minutes after the update to allow the Edison to finish configuring. Do not unplug the Edison during that time!

OS X

Open a terminal (Finder → Applications → Utilities → Terminal).

OS X Terminal

We need to install a few utilities in order to flash the Edison from OS X.

Install Homebrew:

ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

Press RETURN and enter your password when asked to continue the installation process.

Homebrew might need to clean or check things before we use it. Run:

brew doctor

Once Homebrew has been installed and cleaned, use it to install a few other utilities:

brew install coreutils gnu-getopt dfu-util

Change to the Edison Yocto image directory in your Downloads. The directory name will be different depending on the version of the image you downloaded earlier.

cd ~/Downloads/edison-iotdk-image-...

Run the install script.

sudo ./flashall.sh

You will see a message like “Now waiting for dfu device.” At that, plug the USB micro cable into the OTG Port of the Edison, and plug the other end into an open USB port of your computer. You should see the script start to flash the Edison in the terminal. Wait while that finishes (it could take a few minutes).

Flashing the Edison from OS X

You will should get a notice that the flashing process is complete. Wait at least 2 more minutes after the update to allow the Edison to finish configuring. Do not unplug the Edison during that time!

Linux

Navigate to the Yocto image that you unzipped. Open a terminal and enter:

cd Downloads/edison-iotdk-image-...

Where the directory is the unzipped Yocto image (e.g. edison-iotdk-image-280915). Run the install script:

sudo ./flashall.sh

You will see a message like “Now waiting for dfu device.” At that, plug the USB micro cable into the OTG Port of the Edison, and plug the other end into an open USB port of your computer. You should see the script start to flash the Edison in the terminal. Wait while that finishes (it could take a few minutes).

You will should get a notice that the flashing process is complete. Wait at least 2 more minutes after the update to allow the Edison to finish configuring. Do not unplug the Edison during that time!
