Yes, the error occurs every time that I open mBlock 3.4.1 and requires me to reset the board to mCore. I’m using MacOS Sierra (latest patch set) and the beta WinChipAhead driver.
Steps to duplicate
- Load program
- Go to Arduino mode
- Upload to Arduino
- Compilation/Upload fails
- Change board type to Arduino Uno
- Go to Arduino mode
- Upload to Arduino
- Compilation/Upload fails
- Change board type to mCore
- Go to Arduino mode
- Upload to Arduino
- Compilation succeeds
Occurs under MacOS Sierra (10.12.1) / WinChipAhead Beta driver for MacOS Sierra
I don’t think it’s the USB driver, but rather something that has changed between 3.4.0 and 3.4.1.
