AM62L TMDS62LEVM evaluation module (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.

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:
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:
west build -b am62l_evm/am62l3/a53 <my_app>
west 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.
