Finally got some CM3s for my V1. Only been waiting a couple of years since buying the V1. Everything’s lighting up except the USB Node #2 and Ethernet Node #1 (just a dim left link light). I’ve used a USB-ETH adaptor and managed some connectivity with the master, but the other 6 modules are silent. The modules are lite (no emmc) and their SD cards have been imaged with Raspi OS and unique host names. I can’t see any superfluous solder sitting on any pins as per the troubleshooting page on docs.turingpi.com and have also seen references to network problems on Reddit where the result was returning the board for a replacement. Before I embark on that process, does anyone have any clever advice?
