Select Boot Mode (Serial Download 、eMMC、SD Card)

NEX-003 is switched by the DIP switch. Please refer to the figure below to select the mode you want to use.

Serial Download mode

eMMC mode

SD Card mode

Debug (UART, CC1)

CC1 is the NEX-003 DEBUG mode port. It sends signals to the PC via uart to usb.

Please refer to the login screen below. CC1 provides debug information to the PC. The account and password we use here are both user.

UART (UART0, CUR1)

CUR1 is the NEX-003 UART mode port. It sends signals to the PC via uart to usb.

We demonstrate how to use USB to UART to transmit signals between the two sides. Please refer to the figure below for the result.

I2C (I2C2, CI2C1)

CI2C1 is the NEX-003 I2C mode port. It sends signals to the i2c device.

We demonstrate how to use PW407 check I2C signals . Please refer to the figure below for the result.

TypeC (CU1)

NEX003 can use CU1 to overwrite emmc. Install YOCTO as a storage device. Please refer to the following link for quick start.

The following picture shows the overwriting completed pattern for reference.

COM(RS485, CCD1)

NEX003 RS485 test method is RS485_D+ connected to RS485_D+, RS485_D- connected to RS485_D-

Cutecom can be used as a test tool

Install minicom using the following command

 user@imx8mpevk:~$ apt-get update
 user@imx8mpevk:~$ apt install minicom

The test results can be seen in the following pictures

DIO (2DI/2DO, CCD1)

NEX003 BDIO test mode is to connect BDI1 and BDO1, and BDI2 and BDO2 can use gpiod as test tool

BDI1 -> GPIO5_IO11 , BDO1-> GPIO5_IO10

BDI2 -> GPIO5_IO12 , BDO2-> GPIO5_IO13

The test results can be seen in the following pictures

If you use libgpiod 2.0, refer to the following test command

Take BDI1->GPIO5_IO11 as an example

user#timeout 0.1 gpioset -c 4 11=0

user#timeout 0.1 gpioset -c 4 11=1

user#gpioget --numeric -c 4 11

MIPI Camera

NEX003 mipi camera is used with tevs_ar0821

Search for cheese software in OS and open it to see the image

Ethernet (CL1)

NEX003 have two LAN, use RJ45 to connect to the Internet

Provides you with the ability to connect to the Internet
