Updating the Fomu Bootloader
----------------------------
To update your Fomu, download the appropriate ``-updater`` dfu release from
`foboot <https://github.com/im-tomu/foboot/releases/latest>`__.
#. Download the :file:`{board type}-updater-v2.0.3.dfu` file.
* If you have a ``PVT`` Fomu, download |pvt-updater|.
* If you have a ``Hacker`` Fomu, download |hacker-updater|.
#. Run :file:`dfu-util -D pvt-updater-{version}.dfu`.
#. Your Fomu will flash rainbow for about five seconds, then reboot and go back
to blinking.
#. To verify it has updated, ``dfu-util -l`` and check the version output.
.. |pvt-updater| replace:: `pvt-updater-v2.0.3.dfu <https://github.com/im-tomu/foboot/releases/download/v2.0.3/pvt-updater-v2.0.3.dfu>`__
.. |hacker-updater| replace:: `hacker-updater-v2.0.3.dfu <https://github.com/im-tomu/foboot/releases/download/v2.0.3/hacker-updater-v2.0.3.dfu>`__
