The interesting thing about the BeagleBone is there are two microcontrollers inside the processor chip that you can use if you want to do anything that's genuinely real-time. (I'm in the middle of using these to emulate an Ethernet for the Alto restoration. There's a big learning curve to use them.)
As far as the file system abstraction, I'm not sure if it's clever or over-engineered. It seems like a whole lot of infrastructure to simply flip a bit. And the BeagleBone device trees - I can see why they did that, but it seems like there must be a better way.
- revelation 10y agoDo you use the MII interface for the PRU-ICSS to do the Ethernet? I can't really understand why they don't have even a one-page documentation on that stuff, but I've found code to interface that in parts of their industrial SDK.
- kens 10y agoI'm using bit-banging since the Alto's Ethernet is only 3 megabits/sec so the PRU (the microcontroller inside the processor chip) is fast enough. I'm pretty sure that using the MII (Media-Independent Interface, i.e. the Ethernet controller inside the PRU inside the chip) would just cause me more problems.
