Devices

Serial Port

This board configuration uses a single serial communication channel with the MAIN domain UART (main_uart0).

SD Card

Build the AM62L SDK as described here Building the SDK with Yocto using MACHINE=beaglebadge-ti. Flash the resulting WIC file with an etching software onto an SD card.

Build Zephyr, for example build the Hello World sample with the following command:

# From the root of the zephyr repository
west build -b beaglebadge/am62l3/a53 samples/hello_world

This builds the program and the binary is present in the build/zephyr directory as zephyr.bin.

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 start zephyr.bin:

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

The Zephyr application should start running on the A53 cores.

Debugging

The board is equipped with JTAG exposed over an edge SOICbite connector.
