I love the BeagleBone boards. Some of my favorite SBC's, especially the Octavo OSD335x-based [1] PocketBeagle [2].
For anyone interested in more examples and explanation of PRU programming on BeagleBone boards this repo is really good: https://github.com/MarkAYoder/PRUCookbook https://github.com/MarkAYoder/PRUCookbook

- Gibbon1 8y agoWe use them at work. The NAND flash is really solid compared to what we were using previously. However we also use a super cap to keep the lights on while the system shuts down too. Notable though the power controller for the BeagleBone has a serious issue with brownouts/slow power application. If the power ramps up too slowly it'll hang and needs to be manually reset. That's a not ready for prime time sort of thing. We solve it with a small uP that monitors the BB and kicks it if it fails to power up or hangs.

- Gibbon1 8y agoYou could, though I've found analog jungle logic to do things like this tends to end in sorrow. With a watchdog uP you can also force the host to verify it's actually functioning. Bonus is that cures 'failed to boot properly' Which happens. We do that to avoid having to send out a tech. Amusingly a friend maintains a similar system on satellite hardware.
