Flash via AN945: EFM8 Factory Bootloader HID.

Install

-------

.. code-block:: bash

    sudo apt install libusb-1.0-0-dev libudev-dev

    python3 -m pip install efm8

Usage

-----

Communication is over USB-HID. This is implemented via the `hidapi `__ pthon wrapper for the `hidapi `__ native library.

On linux you can use udev to grant access:

.. code-block:: bash

    echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="10c4", MODE="0666"' | sudo tee /etc/udev/rules.d/70-silabs.rules

    udevadm trigger

.. code-block:: bash

    efm8 firmware.hex

Also includes an example that resets a https://u2fzero.com/ into the bootloader and flashes in one command.

.. code-block:: bash

    u2fzero firmware.hex

And a way to (slowly) read the firmware back

.. code-block:: bash

    efm8_read firmware.hex
