| |
| 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_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 |
