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. Intel® Edison Troubleshooting Guide 3 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) Intel® Edison Troubleshooting Guide 4 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. Figure 3. Firmware Installation 9. Once this process is successfully finished, your Edison now runs the latest firmware. 10. You are now ready to build systems on this platform! Intel® Edison Troubleshooting Guide 5 Mac OS X 1. Download the latest Yocto complete image at https://software.intel.com/edison-image/latest 2. Extract the downloaded file to a directory. 3. Open Terminal. 4. Navigate to the directory you extracted the image to. If you are not familiar with the command line, refer to page 6 of Tutorial 2. 5. $ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 6. $ brew install dfu-util coreutils gnu-getopt Figure 4.

Do NOT unplug the cable while the installation process is running. Figure 6. Firmware Installation 11. Once this process is successfully finished, your Edison now runs the latest firmware. Intel® Edison Troubleshooting Guide 8 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. Intel® Edison Troubleshooting Guide 9
