Hi all,
I am using Genuino 101 and it cannot be detected by my computer through USB (no COM port detected).
Also, when I just plug in or press the "MASTER_RESET" button, the "FAULT" and "RX/TX" light will show up for a few seconds. (video attached: https://youtu.be/6CaWYpjqbM4)
The thing first happened when I tried to connect a second 9V battery to the board (not connected to USB at that time). Then the red "FAULT" LED light up and the board stop working.
Did I "brick" the board? Is there a way to recover? What is the reason leading to this?
Thanks in advance for any suggestion.
Depends...
Did you accidentally feed to board with 18 volts (2x9) or touch 9 volts to anything else by accident ?
What do you see with everything disconnected and powered from the USB ?
Does anything get HOT ?
Was there a puff of magic blue smoke at any time ?
Does anything show in device manager (assuming windows) ?
Hi Bob,
Thanks for the reply.

I dont think that is likely because I did it on a breadboard, everything looked good when using the first battery. When I added in the second one, the worst case should be +9V and -9V form short circuit between themselves i dont think it will damage the board.
Nothing is hot and no smoke come out as well.

When powered with USB, the power light is on, and a red "FAULT" light and green "RX/TX" light will be on for a few seconds. (same as what i uploaded in the youtube video)
My Windows had no response when I plugged in the board, the device manager did not even refresh. When I refresh manually nothing came out.
I am going to assume(hopefully) that the board is still good and look at why windows may not see it.
With any luck it might be something else but please don't hold your breath on that.
Make sure NOTHING is connected to the board.
Which version of the IDE
What is the OS version
Tell us which type of USB ports you are using.
If its USB 3.0 then you should try it on a USB 2.0 port OR use a powered USB 2.0 hub between the 101 and the computer.
Hi Bob,
I tried on Win 10, Arduino 1.6.12 and both USB 2.0 & 3.0
Actually the same thing happen ("FAULT" light and "TX/RX" light show up for a few seconds) every time when the board connected to a power source (both USB and battery)
No device detected through the Device Manager.
I guess it might be related to sketch or firmware issue? Maybe when I tried to connect the second battery, somehow the running sketch interfered with the firmware and caused chaos?
Actually I am also curious what does the red "FAULT" light indicate?
