Hoping someone can help me debug this! I assembled my A06 DevTerm and everything went together smoothly. However, when connecting USB-C power and hitting the power button, nothing ever shows up on the display. A few notes:
- I do not have 18650 batteries on hand, so I’ve been trying to run solely from USB power. Let me know if this is not supported! The charger is for a Macbook and should provide plenty of amps.
- The green power LED does come on, but the monitor never comes up.
- There is a fairly loud buzzing/whine noise which comes from the unit when powered on. I’m not sure precisely where this is originating, but it sounds like it’s coming from the mainboard or the A06. Could this indicate something is defective?
- I wasn’t sure whether the SD card had been pre-imaged, so I re-imaged it with the A06 image found here. Still no dice.
