You're right, there's the BIOS POST for example. PowerPC machines did way better with their "OpenFirmware (tm)", or was is SPARC? I loved these things, powerful bare-metal shells. > Back in the days of the VAX 11/750 all of that microcode (what it was called I know VACOS (VAcuum Cleaner Operated System) but I do not know VAX, sorry! ;) > then) was on a cassette tape you turned the key to boot from.

I don't think i want to run my system tests from QtC. Sounds like a click bait. You could argue, that using Boot2Qt with their qemu stuff, you could achieve that. But I still think it's the wrong abstraction level. A simulated Boot2Qt always runs in a x86 vm. It does boot the same embedded linux distro but it doesn't boot on the same virtualised hardware. I guess you could tweak the arch in Yocto, maybe... is it worth? Anyway, it's an interesting topic, for example are we talking factory site auto-tests (eg. flash) or customer site auto-test (eg. remote update)? How much HW can you emulate/simulate that will make your tests meaningful? > Oh! Even better example.
