Abstract

This technical User’s Guide describes the hardware architecture of the AM62x SKEVM, a low cost Starter Kit built around the AM62x SoC. The AM62x processor comprises of a Quad-Core 64-bit Arm®-Cortex® A53 microprocessor, Single-core Arm Cortex-R5F MCU and an Arm Cortex-M4F MCU.

The SKEVM allows the user to experience great dual display feature through HDMI (over DPI) and LVDS, as well as industrial communication solutions using serial, Ethernet, USB and other interfaces.

The SKEVM can be used for your display application(for example a HMI or control panel) with either a HDMI display or an external LVDS panel, up to 2K resolution. It's high performance (up to) Quad-A53 ARM cores at 1.4GHz, with rich industrial interfaces, offer control and communication capabilities for a wide ranges of applications, such as PLC, automation control and monitor/supervisor systems. In addition, SKEVM can communicate with other processors or systems, and act as a communication gateway. The embedded emulation logic allows for emulation and debugging using standard development tools such as Code Composer Studio™ from TI.

Note: This evaluation board is a pre-production release and has several known issues that should not be copied into a production system. E1 EVM Shown in product photos.
