After downloading and running a program to a board, unplug the serial connection and replug to a power source, it is unable to run the program by pressing the reset button. What solution can be solved?

Note: we can get a solution by using Mu IDE editor which generates a HEX file to be uploaded to the board. Possible to reset the board to run. Not so with uPyCraft IDE?

Hi thanks for your support.
Please use the tool you prefer.

Found the solution... need to download main.py beside boot.py, not any other names.
