@dalias @StryderNotavi @gantua given that early versions of the #RaspberryPi could be crashed / kernel panic'd with a xenon flash, I'd not be surprised of that possibility.
- And given the early versions up to & including #Pi3B are supposed to run off #MicroUSB, sometimes with as little as 500mA ( #Pi0v1.2 ) and maxing out at 2,4A ( #Pi3Bplus ) I'm shure they are at the lower end of tolerance re: SPI bus voltages for #SD / #microSD cards...
Add to that a card that just barely keep up with it and we get those too tight tolerances between the two, so yeah, it all comes together.
- OFC this is a hardware flaw and not really fixable except with a new board version / swapping certain components.
