The flakiness I have seen is mainly with the USB subsystem, for example every other time the RPI3B here loads u-boot it detects 3 devices, and the next 4 devices, this is from cold start without any soft- or hardware changes. Another issue I've seen is file system corruption but of course this is current and I do not expect everything to be top notch. Flaky or not, would be nice to try another arm or arm64 platform just to learn, preferably one of the bigger ones, already got an Orange Pi R1 to delv into now. Cheers,
