What's more, many rs232-usb chips also have a few GPIOs which can be controlled over USB. This could be used to give the host the USB console is connected the ability to turn on/off eMMC and the SPI flash chip, without needing to open up the PBP and flip a switch. Would make the disable eMMC, boot, re-enable eMMC while running process used to reflash a bad eMMC a lot easier.
