WOW - that is a turnaround time (working in IT myself
the CosmosEX is brand new, got it only a few weeks ago
updated - so I must have been a few days out - and the error went away, at least when working with a fresh booted CosmosEX
Yeah, this Raspberry Pi 3 compatibility thing got solved 5 days ago, so that update was necessary
It was linux configuration issue, they (Raspbian) switch the RPi core frequency up and down, depending on the system load, and the trouble was that this core frequency was also used for generating SPI clock, which was wrong because of that core frequency going up. So now the core frequency is fixed to 250 MHz, the SPI works fine (the instruction (arm) frequency still toggles between 600 MHz and 1200 MHz depending on the load).
