Here is my issue:
Approximately 2 weeks ago my company ordered a brand-new Qualcomm Dragonboard 410c at arrow.com.
As we received the board, everything has been working properly. Android was pre-installed and we were able to get familiar with the default OS.
After that we installed Windows 10 IoT Core to compare both operating systems.
Since we know now, that Windows IoT Core does not qualify for the project, I was about to re-install Android today
I’ve been following the instructions provided in the official manual provided by 96Boards on Github: https://github.com/96boards/documentation/blob/master/consumer/dragonboard/dragonboard410c/guides/AndroidUserGuide_DragonBoard.pdf
The relevant section is chapter 2.2 (Installing Android from Host PC).
In step 2 (Bring the board into fastbot-mode) I followed the given instructions:
- Ensure the boot switches S6 are all set to 0000
- Connect the micro-usb cable to the board
- Press and hold the Vol- button (S4)
- Connect the power supply to the board
As I was plugging in the 18V power-supply-cable with the button S4 pressed, the board was increasing its temperature rapidly before it began to fume.
I immediately disconnected the power supply.
At that time the Dragonboard was only connected to my computer via micro-usb and to the power supply.
After resting for 1-2 minutes, I tried to reboot the board without pressing the S4-button - the board started to click periodically (1-2)/second.
This is what I’ve tried to get it working again:
- Boot the board using a keyboard/mouse and an external monitor (board starts clicking-sounds, nothing happens)
- Try to re-install Windows IoT Core via USB with DragonBoardUpdate Tool (Switch S6 to 1000) -> Computer does not recognize Dragonboard (board starts clicking-sounds, nothing happens)
- Try different USB-Cables to connect the dragonboard to my computer (Switch S6 to 1000) -> Computer does not recognize Dragonboard (board starts clicking-sounds, nothing happens)
- Boot Android from SD Card (Switch S6 to 0100) -> nothing happens (I used the instructions provided in chapter 2.1)
I’m pretty disappointed about the situation since the board has barely been used.
