Steve and I went offline a bit with this...

Recap... Pi 4B came home Monday and I got it running with regular tools and new Raspbian Buster that's required.

Steve got a version of RPi-JMRI up Wednesday afternoon and I Etched his image to a working SD from a Pi 3B+. No good, never got past a short boot to a command line but that seems to work at least..?

We spent yesterday and this morning working through the issue with Steve kindly working to give me check points and good "try thises" all logical but nothing worked.

Okay I changed two things, the Pi, well, that worked and the software and that didn't so software yes?

No... there was a clue in one test where I saw a message where a log file couldn't be opened, that seemed odd.

So how about this, the SD is broken, happened on the initial load of Steve's image... The boot partition is readable but it or the root partition is now *not* writable..? The Pi can read enough to get some of Raspbian up and do some things but now to go beyond that point and bring up anything else... Like the GUI and then Java/JMRI.

Replaced the card and Steve's image is up on the new Pi 4B all you RPi-JMRI fans!

Thanks Steve and I hope a cautionary tale for all those of you trying to trouble shoot your JMRI system or any computer system for that matter. It may not be what you think! Last attempt to burn card with Etcher produced a tiny red ! and a checksum error hard to notice on the Etcher page big blue completed tiny error...

While I couldn't score a 4 GB model, the speed of the new 4 is quite noticeable.
