i didn't try it myself, but here is what looks like a good description of what you need to do in order to synchronize the Clock of several redpitayas: https://www.koheron.com/blog/2016/11/29 ... ya-cluster

i hope it helps.

This does not synchronize the ADC.

Very true.

In order to sync ADC clocks across RPs you have to physically move a couple of the resistors. You have to reverse this change if you want to go back to the internal clock. Only for the very brave, rich or talented.

yes but it still does not solve the problem. When I change two RP to external clock, where do I get the external clock from? If the clock would be exported to a pin, I could use that. but it is not?!
