that's like... 2-3 seconds from power on, to our firmware running (showing the splash screen is the first thing we do)
then a couple more seconds to have an actually usable device (we can improve that second gap i think; haven't looked much into it yet)
the number one issue with 'more powerful' SoCs people have yelled at me is that most of them are still fucking around in u-boot or whatever by this point.
