> Ideal for use in microprocessors. Seems to be targeted at microprocessors not microcontrollers per the title.

  Could you clarify? I'm kind of fuzzy on those terms. From the top of the article: Cortex-M is the example, and those are what I associate as microcontrollers. Maybe naming conventions? Maybe the former is the CPU, and the latter is the CPU + the periphs, flash, ram? It also mentions heap, which is not something I associate with microcontrollers by default, but I notice a lot of RTOS and allocators lately when I look beyond my own stuff!

    A microprocessor is a CPU. It is a holdover term from when processors got shrunk to fit on a single die.

    The terms are fuzzier these days, but if something claims microcontroller support I expect bare metal or RTOS support and if it says microprocessor I expect a bigger OS - embedded Linux support (yocto, buildroot), standard Linux (install + package manager) or maybe one of industrial RTOS. I’ve had a (quick) look through the docs and I can only find a REPL example running on a standard OS. I’m sure some will argue, but I was merely quoting what I immediately saw in the docs compared to what the hn headline said.

      Oh gotcha! So, A Cortex-A would be an ex of a microprocessor. Sounds like you're right that this may not be for bare metal or RTOS. Although the amount of flash and ram req will work on many MCUs. (But kind of a big overhead; e.g. the one I'm using now is 128k / 32K F/R, but I cheaped out)
