uflash - utility for flashing the BBC micro:bit with Python scripts and the MicroPython runtime
uflash [--runtime RUNTIME] [--watch] [--minify] [source] [target [target...]] uflash [--extract HEXFILE] [source] uflash [--version] uflash [--help]
uflash flashes Python onto a BBC micro:bit or extracts Python source from a .hex file. If no path to the micro:bit is provided, uflash will attempt to autodetect the correct path to the device. If no path to the Python script is provided, uflash will flash an unmodified MicroPython firmware onto the device.
uflash supports the following options: -r, --runtime RUNTIME use the specified MicroPython runtime file -w, --watch watch the source file for changes -m, --minify minify the source -e, --extract HEXFILE extract Python source from given hex file source the Python source file to flash or extract to target path to one or more mounted micro:bit devices -h, --help display usage information and exit --version display current version and exit
If you type the command on its own then uflash will attempt to find a connected BBC micro:bit and flash an unmodified default version of the MicroPython runtime onto it: $ uflash Flashing Python to: /media/ntoll/MICROBIT/micropython.hex To flash a version of the MicroPython runtime with a specified script embedded within it (so that script is run when the BBC micro:bit boots up) then pass the path to the Python script in as the first argument to the command: $ uflash my_script.py Flashing Python to: /media/ntoll/MICROBIT/micropython.hex You can let uflash watch for changes of your script. It will be flashed automatically every time you save it: $ uflash --watch my_script.py At this point uflash will try to automatically detect the path to the device. However, if you have several devices plugged in and/or know what the path on the filesystem to the BBC micro:bit already is, you can specify this as a second argument to the command: $ uflash myscript.py /media/ntoll/MICROBIT Flashing Python to: /media/ntoll/MICROBIT/micropython.hex You can even flash multiple devices at once: $ uflash myscript.py /media/ntoll/MICROBIT /media/ntoll/MICROBIT1 Flashing Python to: /media/ntoll/MICROBIT/micropython.hex Flashing Python to: /media/ntoll/MICROBIT1/micropython.hex To extract a Python script from a hex file use the “–extract” flag like this: $ uflash --extract something.hex myscript.py This will save the Python script recovered from “something.hex” into the file “myscript.py”. If you don't supply a target the recovered script will emit to STDOUT. If you're developing MicroPython and have a custom runtime hex file you can specify that uflash use it instead of the default version of MicroPython in the following way: $ uflash --runtime=firmware.hex
The default MicroPython firmware file is located in /usr/share/firmware-microbit-micropython/firmware.hex.
