What happened? Arduino 1.8.10 is not used. There is a problem that can’t be uploaded to Arduboy !!!
I am having the same issue since upgrading to Catalina.
What should I do? I am very urgent to deal with
Right now if it’s too urgent you might have to try to find a windows computer to compile…
Oh! Too bad… i will try it , OMG
How to fix ? Use window 10 only ?
Any windows version that the Arduino IDE can run on yes.
OS X Catalina dropped 32bit support which why there are a lot of incompatibilities. Arduino is aware of this but there is no solution yet.
Oh!!! 64bit only …/??
Solved in 10.15.2 if someone interested
