Using ampy you can manipulate files on the board's internal filesystem and even run scripts. Options: -p, --port PORT Name of serial port for connected board. [required] -b, --baud BAUD Baud rate for the serial connection. (default 115200) --help Show this message and exit. Commands: get Retrieve a file from the board. ls List contents of a directory on the board. put Put a file on the board. rm Remove a file from the board. run Run a script and print its output.
