+
+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
+
+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+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`_.
