There’s no concept of “reboot” with MCUs, since there’s usually no OS. Likewise there’s usually no concept of segfault, because segfault requires memory protection which is something most MCUs don’t use.
Tesla’s MCU runs Linux. Older ones use a 2012-era Nvidia mobile SoC, while newer ones use something from Intel.
Nah. No way the mcu responsible for braking would run an OS
Didn't they already do an Over-the-Air update to fix the braking time in response to a bad review?
You don’t need an OS for that.
This must be an acronym mixup. We’re talking about the Media Control Unit, i.e. the giant screen in the center of the dashboard responsible for zero safety-critical systems.
MCU in the case of braking and steering is “micro controller unit”.
Yeah, those definitely aren’t running Linux, and the guy here wasn’t working on them.
Yes, The infotainment stuff, like the screen, internal lights, speakers are connected via a low profile third bus system, certainly not the main CAN bus or profibus or firewire. Some, like in the BMW even via WiFi.
These are the systems usually used with Linux or Windows or Android. On top of the important stuff.
