1 Introduction

Upon receiving a fabricated and assembled AM26x-based PCB system, an engineer must visually inspect the board. This inspection must include noting any components with poor solder joints or non-populated components that can cause issues or damage to the PCB at power on.

When bringing up any AM26x-based PCB system for the first time, perform the following steps in this order:

  1. Power checks
  2. Verify AM26x device boot status
  3. Verify AM26x device is alive
  4. Verify AM26x JTAG connection
  5. Run example code to verify program loading and output

This document details the process to be followed to successfully bring-up an AM26x-based PCB system.

Note: AM26x refers to any of the MCU devices in the AM263x, AM263Px, and AM261x families of high-performance microcontrollers.
