This python tool is used by the Arduino IDE to perform common operations like resetting into DFU mode, updating the flash contents of the MCU, performing a factory reset, or getting some basic information about the modules.

While the tool is intended to be used by the Arduino IDE, you are also free to use this tool from the command line.

Location: /tools/feather_dfu/feather_dfu.py

Commands

feather_dfu.py exposes the following commands:

arduino_upgrade

This command will flash your user code (the code compiled in the Arduino IDE) to the appropriate section in flash memory.

You must provide a .bin file as an argument with this command, for example:

featherlib_upgrade

This command will flash the FeatherLib section of flash memory.

You must provide an appropriate .bin file as an argument with this command, for example:

enter_dfu

Causes the WICED Feather to enter DFU mode.  You will know if you are in the special DFU/Bootloader mode because the LED will blinky at a faster than normal rate.

info

Running this command will provide some basic information about your WICED Feather, and can be used when trying to debug issues in the support forums, etc.

When you run the 'info' command you will see results resembling the following:

In order of appearance these values signify:

• The firmware family (normally 'Feather')
• The MCU version (normally 'STM32F205RG*')
• The unique serial number for this MCU
• The 48-bit HW MAC address for this chip
• The bootloader version
• The WICED SDK version
• The FeatherLib version
• The ArduinoCode verison (may be user defined, or may mirror FeatherLib)
• The date the flashed FeatherLib was compiled

factory_reset

This command will perform a factory reset on the WICED Feather, erasing the Arduino user code as well as resetting the non-volatile config memory to factory defaults.

nvm_reset

Resets to non-volatile config memory to factory default settings (but leaves the Arduino user code intact).

reboot

Causes the WICED Feather to perform a HW reset.
