Devices

System Clock

This board configuration uses a system clock frequency of 200 MHz.

DDR RAM

The board has 2GB of DDR RAM available. This board configuration allocates Zephyr 1MB of RAM (0x82000000 to 0x82100000).

Serial Port

This board configuration uses a single serial communication channel with the 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.

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 Building an Application for more details. Here is an example for Hello World.

# From the root of the zephyr repository
west build -b phycore_am62x_a53 samples/hello_world

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:

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