    Edison breakout board LED flashing 3 times and won't connect

    Greg-G

      Hey all, so just like the title says my Edison with the arduino breakout board has stopped working. So the details: the Edison was connected to a laptop through USB and was working just fine 5 minutes prior to the incident. A motor encoder was connected to 5 volts, ground, and two digital inputs on the breakout board. I started noticing an LED was flashing rapidly so I disconnected the encoder and now the board will not connect to the laptop and the LED only flashes three times when the reset button is switched and when it is first connected to the laptop. This makes no sense to me since the encoder was not powered and the Edison was only connected to the laptop which was not running any code. I thought I could have shorted out the Edison, but the connections were solid. Has anyone experienced something similar or know what's going on? Intel has a horrible support service and I have not heard from them since Friday..

          Hi Greg-G,

          That's a weird issue. Did you use the Edison for other projects before using it with the motor encoder? Additionally, when you power up the board and both USB cables are connected, what's the status of the COM ports in the Device Manager? Could you take a screenshot of the Device Manager so I can check the COM ports’ status?

          I recommend you to try to re-flash your Edison. You could use the Flash Tool Lite for this, or the alternative method that uses the flashall script. In the following guide you will find a brief description of each method: Flashing the Edison Module

            My partner, Joe Deese, and I have tried to contact Intel through their online chat service, but they said it would take a few days to get a specialist. They emailed him on Saturday askig for his information and then stopped contacting him.

              It shows the serial port, but not the Edison drive. We tried reflashing last friday, but we're unable to since we can't access the Edison. Edit: we actually had to buy a new Edison because our last one stopped working as well, but that one had the rapidly flashing LED. This new Edison was used to power two DC motors to move a cart ( still connected to the laptop), which worked perfectly fine.

                Hi Greg-G,

                It's not recommended to use the Edison board to power external circuitry or devices like DC motors. I recommend you to power the DC motors using another power source.

                If I understood you well, you currently have two damaged Edisons, right? I recommend you to submit a warranty ticket using the following form: http://www.intel.com/support/mailform/maker/edisonwarrantyemail.htm. The Warranty Team might be able to help you in a better way with your modules.

                  OK, that is understandable, but the DC motors were driven by motor drivers connected to a 12 volt battery. The signals coming from the motor drivers were the only things connected to the Edison.

                    Hi Greg-G,

                    I thought you were powering the DC motor directly from the Edison board (using the 5V output header). If you were using a 12V battery to power the DC motors, I'd say that the hardware setting was fine. Anyhow, since you are not able to flash the Edison, I recommend you to submit a warranty ticket.

                      No, sorry for the misunderstanding, but I know that the Edison could not handle that type of current. Do you know how long it would take to submit a ticket and get it working again? We have a final project due in May and we cannot afford any more time. I understand this is not your fault, but after defeating two Edisons, it seems this microprocessor is too sensitive to handle something as simple as moving an object with two DC motors and a motor encoder. We have multiple sensors we have yet to test and a voltage regulator to power the Edison, but I am too afraid to actually use this thing for anything practical.

                        Hi Greg-G,

                        The Warranty Team will contact you within the next 24 hours after they receive the ticket. The troubleshooting process shouldn't be so long since we have discussed the issue in this thread (you can point to this thread when you submit the ticket). However, they might ask you for additional information about the issue. If the board can't be fixed, they will consider offering you a replacement. If the possibility of replace the module is considered, then the process might take around 2-3 weeks. This period of time might vary, but you can assume that it'll take some time. Considering the fact that you are short of time, I recommend you to consider other options for your project just in case. Submit the warranty ticket, the Warranty Team will help you with the issue, but if the process takes more time than the expected, you will have at least other options to continue with your project.

                        Regards,
