3. Demo Setup

This section describes the demo setup.

3.1. Hardware Requirements

•CrossLink-NX Voice and Vision Machine Learning Board, Rev. B

•USB 3.0 A to Micro B cable (To load firmware in FX3 and to run demo using video visualizing tool), USB 2.0 A to

Micro B cable (to program Crosslink-NX VVML board)

•Personal computer

3.2. Software Requirements

•Lattice Radiant™ Programmer version 3 (Refer to http://www.latticesemi.com/programmer)

•Cypress - EZ-USB FX3 Software Development Kit (Refer to https://www.cypress.com/documentation/software-

and-drivers/ez-usb-fx3-software-development-kit)

•Video visualizing tool to see output, user can use one of below tool:

1. VLC Media Player: https://www.videolan.org/vlc/download-windows.html

2. Windows Camera APP: To use windows camera app user must change default webcam if other camera device is

connected to system. For more info user can follow steps mentioned in link: https://answers.microsoft.com/en-

us/windows/forum/all/how-to-change-default-webcam-in-windows-10/1e8377c8-4fd5-4e9c-8ab6-67913c5c8e0c.

4. Programming the Demo

This document describes the FaceID Demo running process using the Crosslink-NX™ Voice and Vision platform.

To Run the demo user will need prebuilt ‘.mcs’ and ‘.bit’ file to program the Crosslink-NX VnV board.

4.1. Package Folder Structure

Figure 4.1 shows the demo folders and files after unzipping the package.

Figure 4.1. Demo Package Folder Structure

4.2. Load Firmware in FX3 I2C EEPROM

To load the firmware:

1. Connect jumper J13, user refer to section Functional Description for location of jumper on VVML Board.

2. Connect the USB3 port of the CrossLink-NX VVML Board (Rev B) to the PC using the USB3 cable.

3. Open the USB Control Centre application. The Cypress FX3 SDK should be installed.

4. Press the SW2 button to reset the FX3 chip. Figure 4.2 shows the boot loader device screen.

5. Select Cypress USB Bootloader.

6. Click Program > FX3 > I2C E2PROM.

7. Locate and select the FX3 image file for the 640 × 480p 60 Hz 16 bit configuration.

8. The Firmware is programmed in the I2C E2PROM.

9. After the operation is completed, a message acknowledging successful programming is shown at the bottom

taskbar.

10. Remove jumper J13.

11. Power OFF and then power ON the board.

12. The FX3 boots from I2C E2PROM.

4.3. Programming the CrossLink-NX Voice and Vision SPI Flash

4.3.1. Erasing the CrossLink-NX Voice and Vision SRAM Prior to Reprogramming

If the CrossLink-NX device is already programmed (either directly, or loaded from SPI Flash), follow this procedure first

to erase the CrossLink-NX SRAM memory before re-programming the SPI Flash. If you are doing this, keep the board

powered when reprogramming the SPI Flash (so it does not reload on reboot).

To erase the CrossLink-NX device:

1. Launch Lattice Radiant™ Programmer. In the Getting Started dialog box, select Create a new blank project.
