I just got a BeagleBone Black and am playing with it. I was comparing with RPi and it won given its processor (later ARM version), onboard storage, and most of all the number of buses and connections supported. Not sure what I'll do with it yet though. I have been fascinated by its two PRU units. There are 200MHz 32bit realtime micrcontrollers that execute a simple set of assembly instructions. They can run mostly independent of the main CPU and kernel. |

Sliding off-topic... Is the hwRNG in the BBB accessibel in user-space yet? Last time I looked it wasn't but there seemed to be people working on it.
I have a use in mind where the better CPU power of the BBB would be a benefit (and the better video support and so forth of the rPi would be meaningless) but only if the RNG is easily accessible (the Pi's is exposed as /dev/hwrng once a simple module is loaded) and pumps out bits at a good rate (~550kbit/sec is what I got when I timed the Pi which is far more than I need but I don't want too slow a rate obviously).
