You can run on the N100 a program that would monitor continuously the RP2040, e.g. by reading periodically the state of a GPIO pin or of a variable in the internal memory. Such a program can shutdown all the SBC.
- gdedvhy 2y agoWhile this is true, it misses most usecases, since you need cooperation from the Intel chip and you cannot start it up again after it shut down
- dvdkon 2y agoI suppose the usecase would be a "poor man's IPMI", a separate chip dedicated to monitoring the main system, with the ability to power if off and on. Sadly most(?) x86 systems don't offer a non-visual way to access BIOS/UEFI settings (like ARM boards usually do with uBoot over serial), so the utility of such monitoring without video input is limited, but just being able to remotely reset a system via a built-in chip would be very useful.
