Troubleshooting
Find the problem you have encountered from the list below and follow the instruction.
1. The Edison keeps rebooting.
Ø Step 1. If you are using a USB cable to power on the Edison on the Arduino
breakout, make sure the breakout board is in “device mode”. If the problem is not
solved, proceed to Step 2.
Ø Step 2. Please make sure your Edison is supplied with enough power. Use a
powered USB hub or an external power supply. Make sure the Edison is not
driving any components the power supply can supply enough power to. For
example, servo motors draw lots of current. If the problem is not solved, proceed
to Step 3.
Ø Step 3. Make sure the Edison compute module is thoroughly pushed onto the
breakout board. Securing the module with nuts help ensure that the module is well
connected. If problem is not solved, proceed to Step 4.
Ø Step 4. Proceed to “Updating Firmware” section.
2. I forgot the login password.
Ø Step 1. Proceed to “Updating Firmware” section.
3. I cannot connect to a network via WiFi.
Ø Step 1. Log into the Edison and enter “rfkill unblock all”. If the problem is not
solved, proceed to Step 2.
Ø Step 2. Enter “ifconfig wlan0 down” and then “ifconfig wlan0 up”. If the
problem is not solved, proceed to Step 3.
Ø Step 3. Enter “vi /etc/wpa_supplicant/wpa_supplicant.conf”. Delete everything
except the first eight lines as shown in Figure 1.
Figure 1. wpa_supplicant.conf
Then, reboot the Edison and configure WiFi again. If the problem is not solved,
proceed to Step 4.
Ø Step 4. Proceed to “Updating Firmware” section.

Updating Firmware
Note: The method provided in this section may be different from Intel’s official method. Please
adhere to the steps described below to avoid problems.
1. Toggle the switch to enable “device mode”.
2. Connect a micro USB cable to the multi-gadget micro USB port and follow either of two
options below to connect your Edison to your computer.
1. Important: If you have a powered USB hub, please connect the USB hub to your
computer and the USB cable to the USB hub. Otherwise, your Edison may not be
supplied with enough power and reboot occasionally.
2. If you are using an external power supply for your Edison, a powered USB hub may not
be necessary. Your Edison can be directly connected to your computer.
3. The board will power on. Wait for it to finish booting. You can look at the on-board LEDs
that indicates the booting progress as shown in Figure 2.
Figure 2. Board Close-up
4. Unplug the USB cable from the Edison board’s multi-gadget port and make sure the Edison
is turned off (the on-board LEDs must be off).
5. Then, follow the steps below for your computer’s OS. (Windows on page 5, Mac OS X on
page 6, and Linux on page 7)

Windows
1. Follow the instruction on https://software.intel.com/en-us/get-started-edison-windows-32-
step2 to install the USB drivers (CDC, RNDIS, and DFU).
2. Download the latest Yocto complete image at https://software.intel.com/edison-image/latest
3. Extract the downloaded file to a folder.
4. Download dfu-util.exe at https://www.dropbox.com/sh/jhzwqm355guccj9/AACvh1Nrv69N
Kt-LZXWtCDyia?dl=0.
5. Put dfu-util.exe into the folder you extracted the image to.
6. Double-click on a Windows Batch file named “flashall” in the folder.
7. When you see a message “Please plug and reboot the board”, plug a USB cable into the multi
-gadget port and wait for a few second for your Edison to finish booting.
8. Do NOT unplug the cable while the installation process is running.

Firmware Update Troubleshooting
If the firmware is not being properly installed, try to steps below.
Step 1. Please make sure your Edison is in “device mode”.
l The switch near the USB port on your Edison needs to be in down position.
Step 2. If you use a Windows machine, please check if the USB drivers are installed
properly.
1. Connect your Edison to your computer via multi-gadget port.
2. Open Device Manager.
3. If you can find “Edison” listed under “Other devices” with “!” in a yellow triangl
e, you need to re-install the drivers.
4. Right-click on “Edison” and click on uninstall.
5. Follow the instruction on https://software.intel.com/en-us/get-started-edison-win
dows-32-step2 to manually install the drivers.
Step 3. Please check whether your computer recognizes your Edison as a mass storage
device. If your computer does not, the firmware installation was interrupted and the image is
corrupted. Try this section again and please keep the USB cable plugged for few minutes
after the installation process is finished.
