I mean... I can at least tell you that we do this in practice all the time (with generally no issues). The SPI flash is not electrically isolated, so yes, you're gonna leak some current into the SoC when you do this (there are 100Ohm limiting series resistors so it's not a complete short). I've never heard of a Chromebook board dying from this but I can't legally guarantee you anything, of course. _______________________________________________ coreboot mailing list -- [email protected] To unsubscribe send an email to [email protected]
