[Help Wanted] BeagleBone Blue Does Not Turn On (No LEDs nor USB Detection)

[turibiusrozario]

Expected Behavior

Plugging in USB or 12V barrel jack power supply to BeagleBone Blue (BBBL) should

1. Enable the user LEDs;
2. Turn the "ON" LED on;
3. Be recognizable by Windows (if plugged in by USB).

Actual Behavior

Using the USB or 12V barrel jack power supply has the following characteristics:

• Momentarily flashes once the "ON" LED;
• All other LEDs are off for the entire duration;
• When specifically the USB is plugged in:
  • No USB is detected by Windows.;
  • SSH at 192.168.7.2 fails;
  • Pinging 192.168.7.2 fails.
• When specifically the 12V barrel jack is plugged in:
  • The "CHG" LED glows for the entire duration.

This issue began when the 12V/2A barrel jack power supply was plugged into a powered off BBBL. At that time, the BBBL LEDs glowed as usual, and immediately afterwards, turned off (excluding the "CHG" LED).

Note: The barrel jack power supply was previously used with no concerns.

Attempted Solutions

• Holding down the SD (boot select) button while powering on (either by inserting USB, barrel jack, or by pressing the POW (power) button) when a bootable microSD card is present.
• Holding down the POW button.
• Holding down both SD and POW button at the same time or one after another and other button pressing configurations.
• Pressing the RST button.
• Reflashing the SD card with the latest image (note that the eMMC already had the latest image) and then inserting it into to the BBBL

Pressing the POW button momentarily flashes the "ON" LED once.

Using a multimeter, 5V was detected across the GPS port (pins identified from the PINOUT section of this wiki) suggesting that the whole circuitry may not be dead.

I have the same problem. Have you solved it?

@aritomas , unfortunately not.
