BeagleBone Green Wireless turns itself off after 10-40 seconds

Hello!

My BBGW consistently turns itself off, no matter what power supply or image I use. It consistently acted the same on both of my BBGW.

With default factory configuration:

Somehow I can get it to work if I plug my serial connector in. But then after the stage where the BBGW shuts off the LED pattern flashes like this:

On | Off | On | Off
Off | On | Off| On

I am able to connect to the board in this stage. I’ve tested both 500ma and 1A USB chargers and none of them seem to work.

Thanks for any help,
Alek

Hi Alek,
I think you need more than a 1A supply. I use one of these
https://www.amazon.co.uk/Charger-RAVPower-4-Port-Charge-Smartphones-White/dp/B018Q7HNRQ/ref=sr_1_4
to power 4 BBGWs.
I suspect the board is suffering a brown out when the WL1835 does its short calibration (a couple of ms but at ~500mA).
