Try to "flash" python code onto my micro:bit board.
What steps did you take to trigger the issue?
Hi Nicholas, I love using your Mu Editor when teaching computer science in the classroom.
Unfortunately, Mu v1.2.0 and v1.1.1 give me problems when trying to flash to the micro:bit (mb) board.
In a nutshell, the "flash" button does not copy and execute the code on the mb board.
What did you expect to happen?
Flash / execute the code onto the micro:bit board
What actually happened?
Sometimes it says it is flashing in the status bar, and most of the time it does not. It just says it has copied the code to the mb board. When I look at the File system on the mb board, it does not have the program on it. I do see the yellow light for data transfer flashing, but nothing actually happens on the mb board screen. - I have to press the Reset button at the back for the code work, which I am sure it is not what supposed to happen.
If I run it from the Microsoft micro:bit website, it does send the code to the mb board and it does work.
However, in the Mu Editor, if I don't use BBC Micro:bit mode, but if I switch the mode to ESP MicroPython then, the Run button actually executes the code on the mb board.
