Sorry if this is mentioned elsewhere. My searching skills/patience levels are not great!
I have been playing with NCP for a few days and had it installed as I wanted. Then made the leap to install it all in an old USB disk case. But it then didn’t work.
Opening the box and plugging HDMI back in I can see it booting normally, but it doesn’t appear on the network, (despite having a static IP). If I plug in a keyboard and reboot, it all works perfectly.
I hadn’t expected to dedicate a wireless keyboard dongle to the project!
Sounds weird but true!
@OliverV Thanks, when I went back to gather this info I found that I had overwritten the uSD card without backing up. So I went back to the previous backup. This version doesn’t show the same problem!
So sorry, but I will have to walk away from this problem.
