I have many Sparkfun Redboards. I cannot get them to work reliably. They have sometimes worked on Windows, but I do not think they have every worked on Mac. I cannot run the Blink program.
Now, on one Windows 10 computer, I cannot update the Sparkfun Apollo board driver. It says I have version 1.2 and I have tried updating, removing, and manually selecting a different version to load. Whatever I do I get this:
java.lang.nullpointerException. I have tried several versions of the Arduino IDE. I even tried the hourly build. I have uninstalled the Arduino IDE. I even tried the web version, but I see it does not support these board.
How do I get this running?
