CPU's UART0.

SD Card
*******

Download PHYTEC's official `WIC`_ and `bmap`_ files and flash the WIC file with
bmap-tools on a SD-card.

.. code-block:: console

    bmaptool copy phytec-qt5demo-image-phyboard-lyra-am62xx-2.wic.xz /dev/sdX

Building
********

You can build an application in the usual way. Refer to
:ref:`build_an_application` for more details. Here is an example for
:ref:`hello_world`.

.. zephyr-app-commands::
   :board: phycore_am62x/am6234/a53
   :zephyr-app: samples/hello_world
   :goals: build

Programming
***********

Copy the compiled ``zephyr.bin`` to the first FAT partition of the SD card and
plug the SD card into the board. Power it up and stop the u-boot execution at
prompt.

Use U-Boot to load and kick zephyr.bin:

.. code-block:: console

    fatload mmc 1:1 0x82000000 zephyr.bin; dcache flush; icache flush; dcache off; icache off; go 0x82000000
