Hi all,

I gave been successfully working with a SPROG IIv3 and a new RPI 4 (running Raspbian) as a programming station, but am now finding that the USB comms seems to stop working after a bit and JMRI then always shows the Status us UNKNOWN.? If I unplug and restart the SPROG it will work ok for a while and then stop again.

So far I have not seen this discussed anywhere, so any ideas?

Thanks,
Ralph

What version (exactly) of JMRI?

Hi Steve,
It looks like it is a decoder issue actually.? I've been working with a new loco and decoder (DCX76) and am still fiddling, but maybe the SPROG is overloading or something.? ?Can't see anything wrong with the wiring, but have run a couple of other locos ok.? But if I restart JMRI it talks to the SPROG again until I try to programme something than the comms LED stops flashing and I can no longer get the Status to change.

But my JMRI version is 4.18+R36ad3do
