do you guys not have confirmed boot and swizzling to fallback images?

Automotive varies widely between "basically modern Linux systems with proper updates" and the most janky, home-grown update systems imaginable, sometimes even within the same components and teams.

Yah, I know from friends at ford and vw that there's still vxworks and qnx, but even there, good grief, a-b with confirmed boot is about as basic as you can get.

I confess I've seen incredible sloppiness about when a confirmation is done (too early, including in the initial init stages which is way too soon) and watchdogs (spawn off a process that has a while loop stroking the wd - just absolutely pointless).

I've seen kicking and petting the watchdog, but this is my first time seeing stroking

Sometimes the watchdog needs to have fun too, you know.

I've heard all of the above, often "stroking". I never used those because I like systems where you have a random challenge code to respond to. Then the software has to not be acting as wonky to react correctly.

From experience, QNX is actually very nice. I wouldn't say "still using QNX" like it's some crap that nobody would want.

Indeed, a good RTOS from 10-20 years ago works just as good now as it did back then. The only things that change are dev environments and the driver support.
