We've been using Synchrona14 for a few months now as a practical bench DA for high-quality clocks. It has exceeded our expectations, but there are a few issues to be aware of that we want to share.
1. When setting a static IP address, the persistence across power cycles can be fickle. If you have the serial port connected, this is as easy as an "ifconfig" command to fix up. This is really a generic RPi OS issue.
2. When the ADD-ON board is plugged, the RPi doesn't have the SPI access needed to program the clock chips, as documented This would be the case as in (1) above. As a result, the GUI will be served up fine, but you will see "Disconnected". If you remove Jumper J4 on the ADD-ON board, you can have both WEB GUI control and console access at the same time.
Thanks to Mihai, Ciprian, Chris and the ADI team for this fine product!
Made ref one line.
