.. zephyr:board:: am62l_evm

Overview

The AM62L EVM board configuration is used by Zephyr applications that run on the TI AM62L platform. The board configuration provides support for:

• ARM Cortex-A53 core and the following features:

  • General Interrupt Controller (GIC)
  • ARM Generic Timer (arch_timer)
  • On-chip SRAM (oc_sram)
  • UART interfaces (uart0 to uart6)

The board configuration also enables support for the semihosting debugging console.

See the TI AM62L Product Page_ for details.

Hardware

The AM62L EVM features the AM62L SoC, which is composed of a dual Cortex-A53 cluster. The following listed hardware specifications are used:

• High-performance ARM Cortex-A53

• Memory

  • 160KB of SRAM
  • 2GB of DDR4

• Debug

  • XDS110 based JTAG

Devices

System Clock

This board configuration uses a system clock frequency of 1250 MHz.

DDR RAM

The board has 2GB of DDR RAM available.

Serial Port

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

SD Card

Download TI's official WIC_ and flash the WIC file with an etching software onto an SD-card.

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:

.. code-block:: console

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 core.

Debugging

The board is equipped with an XDS110 JTAG debugger. To debug a binary, utilize the debug build target:

.. zephyr-app-commands:: :app: <my_app> :board: am62l_evm/am62l3/a53 :maybe-skip-config: :goals: debug

.. hint:: To utilize this feature, you'll need OpenOCD version 0.12 or higher. Due to the possibility of older versions being available in package feeds, it's advisable to build OpenOCD from source_.
