Flash a Single Partition to Genio EVK
=====================================

You can update a single partition content with ``genio-flash``.

For example, to update the bootloader partition, which contains U-Boot and Trusted-Firmware-A,
use the following command:

.. prompt:: bash $ auto

    $ cd baoshan-{UBUNTU_IMAGE}
    $ genio-flash bootloaders

To update the entire boot firmwares, use the following command:

.. prompt:: bash $ auto

    $ cd baoshan-{UBUNTU_IMAGE}
    $ genio-flash bootloaders mmc0boot0 mmc0boot1 bootassets

The list of updatable partitions is defined in the file ``ubuntu.json``.
For the content and purpose of each partition, please refer to :ref:`Partition Layout <partition-layout>`.
