I disagree that a Raspberry Pi is "definitely not embedded". What if I had an ARM SoC (like in the RPi) running VxWorks or RTEMS controlling a missile? Few would argue that is not an embedded system. What if the RPi is running real-time Linux doing computer vision on an assembly line? What if the timing deadlines are pretty loose (>10 ms), a miss a month is acceptable, and it runs a stock Linux kernel? I would argue all of those cases are real-time embedded systems, albeit with different hard real-time versus soft real-time requirements.
