NXP Semiconductors MIMXRT685-EVK Quick start guide

  • Hello! I've reviewed the Quick Start Guide for the NXP MIMXRT685-EVK evaluation kit. This document describes the kit's key features, including a 300 MHz Arm Cortex-M33 MCU, a 600 MHz Tensilica Hi-Fi 4 DSP and support for High-Speed Octal/QuadSPI. I'm ready to answer your questions about the device based on the information provided in the guide.
  • What is the main processor of the MIMXRT685-EVK?
    What is the speed of the DSP in the MIMXRT685-EVK?
    How much SRAM does the MIMXRT685-EVK have?
    What type of flash memory interface does the MIMXRT685-EVK support for execute-in-place?
    What is included in MIMXRT685-EVK board?

HOW TO GET STARTED
1. Connect the MIMXRT685-EVK board to a PC
using the included micro USB cable to Link USB
J5. The power LED, D11, will illuminate.
2. The MIMXRT685-EVK board comes pre-
programmed with a demo. To verify the demo
is running, LED D9 will blink on/off. The demo
exercises the Cortex-M33 and DSP.
3. For more information on running the demo,
