Been developing on an electron and just brought in a photon to speed up some of the work and stop consuming the cell plan. The unit will reset randomly. It seems that the BGA/Flatpack is not assembled well. I can push on the chip, with a tooth pick or other non metallic item and the photon will reset. Power is provided via USB, I can wiggle this connector and there is no issue. It seems the BGA may have a faulty solder joint.
Has this been seen before?
