=== Backup ===

If desired, backup the original firmware (this doesn't work with dfu-util 0.5, but does with 0.7 or newer). Previous releases of micropython are available from: [http://micropython.org/download/ http://micropython.org/download/] so performing a backup shouldn't be necessary.

If you have other DFU capable devices connected to you machine (for example an Apple Magic Mouse), and you receive the following message:

More than one DFU capable USB device found, you might try '--list' and then disconnect all but one device
 +
 +
you may want to disconnet all other devices, or specify which device's firmware you want to edit by passing either --device or the shorter -d flag to dfu-util. Example:
 +
 +
$ sudo dfu-util --alt 0 -D pybv10-2014-05-19-v1.0.1-24-g5cdff5f.dfu -d 0483

 +

After the the program finished, disconnect the pyboard from USB and remove the jumper between the DFU and the 3.3v ports.

If you need to restore the original firmware, use the following command:

$ sudo dfu-util --alt 0 -D pyboard-original.dat -d 0483:df11 -s 0x8000000
 +
 +
== Alternative: pydfu ==
 +
There is an alternative DFU programmer that is written in pure Python. It can be found here: [https://github.com/micropython/micropython/blob/master/tools/pydfu.py https://github.com/micropython/micropython/blob/master/tools/pydfu.py].
 +
 +
It requires the PyUSB package.
 +
 +
To use pydfu:
 +
 +
<nowiki>$ python pydfu.py -u <firmware.dfu></nowiki>
 +
 +
This will copy the given firmware file to the pyboard. pydfu is much faster than dfu-util.
 +
 +
This will restore everything, including the internal flash filesystem.

Téléchargement

Vous pouvez télécharger la dernière version du FirmWare depuis http://micropython.org/download/

Faites attention à bien sélectionner le FirmWare correspondant à la version de votre PyBoard

Préparatifs

  • First, disconnect everything from your pyboard.
  • Then connect the DFU pin with the 3.3V pin (they're right next to each other) to put the board into DFU (Device Firmware Update) mode.
  • Now connect the pyboard to your computer via USB.

Quitter le mode DFU

Restaurer un ancien FirmWare

If you need to restore the original firmware, use the following command:

$ sudo dfu-util --alt 0 -D pyboard-original.dat -d 0483:df11 -s 0x8000000
