1.1 Introduction

The HSEC180ADAPEVM-AM2 is a SOM to HSEC adapter board that is used to expand the IO and evaluation capabilites of the AM261x controlSOM EVM (AM261-SOM-EVM). The SOM to HSEC adapter board allows interfaces not present on the AM261x controlSOM to be evaluated using a compatible HSEC docking station for powering the system and prototyping using the IO headers and on-board hardware of the HSEC docking station.

The SOM to HSEC adapter allows on-board interfacing with Ethernet, USB 2.0, FSI, JTAG, and off-board interfacing with GPIO pins, MCAN, and LIN using the TMDSHSECDOCK-AM263. By utilizing all three boards in the AM261x controlSOM system (AM261-SOM-EVM + HSEC180ADAPEVM-AM2 + TMDSHSECDOCK-AM263), a customer can create and evaluate complex applications built around the AM261x Microcontroller.

The 180-pin Edge connector is intended to provide a well-filtered, robust design capable of working in most environments. The pinout of the 180-pin HSEC hardware is designed to be nearly identical to the existing AM263x and AM263Px controlCARD EVMs (TMDSCNCD263 and TMDSCNCD263P).

Included in this User's Guide are the hardware details of the SOM to HSEC adapter board and explanations of the functions of the on-board peripherals, locations of jumpers and connectors, and configurations of switches on the PCB. Also included in this guide are instructions on how to start developing software applications using the AM261x controlSOM, SOM to HSEC adapter board, and HSEC docking station.
