Hello everyone, I encountered the following problem.
To run HummingBoard with another B100, in the following configuration http://prntscr.com/7bsamz , installation of the so-called Nitrogen6x core is required. I did not find anything detailed on the Internet, or did not understand what it was for. The meaning of the work of these boards is as follows: An HDMI cable with a video camera is connected to the B100, for example, with the help of gstream, we get video via HmmingBoard.
