IIRC most of the ARM chips can support it, but you'd need something w/ a full BSP unless you want to roll your own (ew).
The cost factors have become pretty interesting. I've moved to ARM-based boards, but in general I've used a standard gcc toolchain along with FreeRTOS-like OSes and for anything beyond "oh you pushed a button" I skip the Arduino IDEs.
- elcritch 10y agoBSP? Ah, gotcha. Yes, I was looking into RPi hardware since it's common enough that I figured there would be BSP support. It appears Lk micro-kernel supports RPi's. Otherwise, Beaglebone has a bit more open hardware board and one or two micro-kernel projects supported it. Not sure what the status of FreeRTOS or Zephyr is on any of the ARM boards. I'd look into setting up BSP for a good ARM chip as it'd make some of the hardware designs easier long term. Any recommendations board recommendations?
- davelnewton 10y agoNo board recommendations--there are soooo many now I have zero clue about "best" or if it even matters. I'm a little wary of the RPi 3 because of the heat issues; there are very competitive boards available at more or less the same price point, often with features I need (like actual SATA instead of via USB).
