I've just come across this conversation in my own search for a rock-solid, embeddable configuration for the BeagleBone Black. I’m trying to develop an embedded controller device that needs to live behind walls, in ceilings and in other inaccessible places. ( It is for the automation of art & other electronic installations.)
>From what I gather here, the BBB is not quite up to the task, without an external watchdog circuit (please correct me if I’m misreading this thread). @John3909: Your suggestion of the GreenPak prompted my own discovery of that tech — it looks great, esp the ecosystem of tools around the platform. In looking around, I found some Silego application notes that implement a hardware watchdog for MCUs. http://www.silego.com/products/352/312/AN-1058.html This might be a useful starting point for anyone using GreenPak for a hardware watchdog. @John3909: Does this design look like it might be a good fit for the BBB? (Not knowing how to read GreenPak internals, it is not obvious to me) Alternately, I'm wondering in the two years that have passed since this thread started, if anyone has developed a hardware watchdog design for the BBB they'd be willing to share. An open-source hardware watchdog for the BBB would go a long way towards ameliorating the hardware issues with the PMIC on RevC, and allow it to prosper as a base for applications where long-term reliability matters. Although I’m first and foremost a software engineer, I've got some electronics chops (albeit mostly digital), but (sadly) very limited hardware design equipment (oscilloscope, etc). [That said, I have iron, and will solder!] I’d be happy to develop & contribute the software components for such a system (I’d envision a library + device tree overlay) if someone(s) else would like to partner up to design the hardware side.
