Voxl 2 mini overheating and rebooting
-
@Moderator I have a VOXL 2 mini that seems to be constantly rebooting and power cycling based on the LEDs.
When I power it on with only the power module plugged in and powered with 12V D1 lights up, but D2 does not. DS2 flashes at a high rate or alternately stays solid. The power supply shows that the voltage is staying high, but the current cycles between around 0.4A and 0A with the DS2 LED also turning off. We noticed that the silver SOC cover was getting hot so held it in front of a fan and it no longer cycled, just held ~0.4A. We measured the voltage arriving to the VOXL 2 mini from the power module and confirmed that it is 3.8v and doesn't dip when powered on. The USB 5V D2 LED doesn't seem to come on and when plugged into a computer there is no indication that a USB device has been plugged in. Holding the ADB button while booting and then plugging it into the computer also does nothing.
Before this the voxl has worked and nothing has really changed in the setup, but it does seem like something has broken. We are wondering if there is a way for us to fix it somehow. Unfortunately it just has the standard SDK installed, so I don't believe the debug port is enabled so I can't check how far into boot it's getting.
Do you have any ideas on things to check?
Thanks

@LucaVertiq Hi, sorry you're running into issues. You should probably try the unbricking process https://docs.modalai.com/voxl2-unbricking/

@Moderator Thanks! I'll give that a shot. Hopefully we can salvage it.

@LucaVertiq , did you try disconnecting EVERYTHING from the board and seeing if it boots? Just bare board with power module.

Hi @LucaVertiq
For clarification (The USB 5V D2 LED doesn't seem to come on and when plugged into a computer ), this LED is an indicator that the 10-pin J3 port is available as a host and has no bearing on the USB-C port operations or plugging into a host PC for ADB.

Hi @LucaVertiq
To me, it seems as if the board went into a power fail condition. Was this in any sort of crash or was it dropped?
LED D2 coming on, then going Off repeatedly is an indication of a continuous reboot cycle (coinciding with your readings of 0.4A, 0A) but there is likely some hardware fault detected by the system preventing it from booting fully. -

Yes, the full boot cycles were observed with just the power module and the voxl. We confirmed the voltage at the voxl was 3.8V and not dropping much below that, so no dead short.

I had ADB'd in to do some things, then when I reassembled it this began happening. It's quite possible I knocked something loose, or possibly some ESD event.
I've been too busy flying vehicles to get to test the unbricking procedure, but Monday I will.
