Powering Up the SolidSense AIOT

The SolidSense AIOT can be powered from any one of three independent sources — pick whichever fits your setup.

Power Options

Source

Connector

Notes

DC input

J1 — HDR 2×1, 3.50 mm

Wide range 5 V–12 V.

Battery

J2 — HDR 2×1, 2.0 mm

For portable / embedded use, no wall adapter needed.

USB Type-C

Type-C port

Powers the board and provides the serial console over one cable (onboard FTDI).

Only one power source is necessary at a time, but it is also acceptable to connect multiple sources simultaneously.

DC Power [J1]

Power Input Polarity [J1]:

Connector Type: Green two-terminal connector [J1].
Voltage Range: 5V-12V.
Polarity:
- + (Positive): Left terminal (as marked in the image).
- - (Negative): Right terminal (as marked in the image).
Mating plug: 2-position terminal block plug, female sockets, 0.138″ (3.50 mm) pitch

The board includes reverse-polarity protection, so an accidentally reversed connection will not damage it. Still, wire J1 with the correct polarity for normal operation.

Software Setup

Cable Setup & Prerequisites

You will need:

A Linux or Windows PC
SolidSense AIOT with SOM (SolidSense AIOT carrier + module)
12 V power adapter — wide input 5 V–12 V; or power via USB Type-C or batteries 3.7V+.
Type-C to USB cable for the console — the onboard FTDI chip provides serial-console access over the same cable

Boot Select

Before powering up the board for the first time it is recommended to select the boot media using onboard DIP switch S1:

Switch

1 (MD0)

2 (MD1)

3 N/A

4 N/A

5 (VDD_3.3V)

6 (VDD_1.8V)

SPI

OFF

eMMC

OFF

Serial Downloader

OFF

MDx = BOOT_MODEx. VDD_BOOT can be either 1.8V or 3.3V (selectable via S1[5] or S1[6]).

BOOT_MODE2 = ‘1’ → fixed to 1.8V at the SOM level
BOOT_MODE3 and BOOT_MODE4 → fixed to GND at the SOM level

Booting from SPI and loading Yocto from uSD card

Set the Boot Switch to SPI Boot Mode

Here is the correct DIP switch position for SPI boot:

Note: The black rectangle represents the switch position. The unit comes with a pre-programmed bootloader on the SPI NOR flash.

Once you set the switches, you can apply the following for booting from an SPI card.

Downloading the Yocto image

Download the Debian image by running the following command on your Linux/Windows PC:

wget https://solid-run-images.sos-de-fra-1.exo.io/RZ/Yocto/vlp4/2026-07-07_adfb4ad/rzv2n-sr-som/core-image-full-cmdline-rzv2n-sr-som.rootfs.wic.gz

For more Debian releases, please visit https://images.solid-run.com/RZ/Yocto/vlp4.

Writing the image to the SD card

Use the following commands for writing the image to an SD card:

gunzip -dc core-image-full-cmdline-rzv2n-sr-som.rootfs.wic.gz | dd of=/dev/sdX bs=4k conv=fdatasync

For more information, please visit Flashing an SD Card .

Note: Plug a micro SD into your Linux PC, the following assumes that the micro SD is added as /dev/sdX and all it’s partitions are unmounted.

SD card insertion

Please Insert the SD card into your device.

Power connection

Connect your power adaptor to the DC jack, and then connect the adaptor to mains supply.

Serial Connection

Please insert the micro USB into your device, then you can refer to Serial Connection for installing necessary serial connection software in Linux/Windows.

Once you installed the necessary serial connection software, you should be able to see the following:

In order to be able to log in, please insert “root” as a username and password.

Streaming Webcam Video from RZ/V2N Yocto to a PC

This section describes how to stream live video from a USB webcam connected to a SolidRun RZ/V2N board running Yocto Linux, and display the video on a remote PC (Linux or Windows) over the network using GStreamer. The streaming pipeline uses MJPEG over RTP, which is supported by most USB webcams and does not require hardware H.264 encoding on the device.

GStreamer provides command-line tools for capturing, encoding, sending, receiving, and displaying video streams.

1. Yocto Image Requirements

v4l2 support
GStreamer core + good/bad/ugly plugins
v4l-utils (recommended)

Suggested additions to local.conf if missing:

IMAGE_INSTALL:append = " gstreamer1.0 gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly v4l-utils "

2. Installing GStreamer on the PC

For Ubuntu/Debian distros:

sudo apt install gstreamer1.0-plugins-ugly gstreamer1.0-plugins-bad gstreamer1.0-libav

For Fedora/RHEL distros:

sudo dnf install gstreamer1 gstreamer1-plugins-base gstreamer1-plugins-good gstreamer1-plugins-bad-free gstreamer1-plugins-bad-free-gtk

For Windows:

Download the Installer: Go to the GStreamer official website and download the appropriate installer for your Windows version.
Run the Installer: Execute the downloaded file. During installation, select "Complete Installation" to install all basic plugins.
Set Environment Variables: To use GStreamer from the command line, add GStreamer to your system's PATH as described here.

For Windows, you might need to configure the Firewall to allow the stream. Make sure that 10.0.0.2 is a private network.

3. Verifying Webcam Detection on RZ/V2N (Yocto)

Before streaming, verify that the USB webcam is detected.

Check USB enumeration

lsusb

Example:

Bus 001 Device 004: ID 046d:085c Logitech, Inc. C922 Pro Stream Webcam

Check video devices

ls /dev/video*

Expected:

/dev/video0

If no /dev/video0 found

Enable UVC driver:

modprobe uvcvideo

Check supported formats

v4l2-ctl --list-formats -d /dev/video0

Typical output:

YUYV 4:2:2
MJPG

Note: The Logitech C922 supports MJPEG, so MJPEG-over-RTP streaming is used.

4. Network Streaming Overview

The RZ/V2N board captures MJPEG frames from the USB webcam (/dev/video0).
Frames are packetized into RTP and sent via UDP to the PC on port 5000.
The PC receives the RTP stream, extracts the MJPEG frames, decodes them, and displays the video.

5. GStreamer Commands

5.1 On the RZ/V2N (Sender – Yocto)

Replace <LAPTOP_IP> with the IP address of the PC receiving the video. Example: 192.168.33.17

gst-launch-1.0 -v \
  v4l2src device=/dev/video0 ! \
  image/jpeg,width=1280,height=720,framerate=30/1 ! \
  rtpjpegpay ! \
  udpsink host=<LAPTOP_IP> port=5000 sync=false async=false

Pipeline explanation

v4l2src – captures video from the webcam
image/jpeg – requests MJPEG format
rtpjpegpay – packetizes JPEG frames into RTP
udpsink – sends RTP stream to the PC

5.2 On the PC (Receiver)

Linux (Ubuntu, Fedora, Debian, etc.)

gst-launch-1.0 -v \
  udpsrc port=5000 caps="application/x-rtp,encoding-name=JPEG,payload=26" ! \
  rtpjpegdepay ! \
  jpegdec ! \
  videoconvert ! \
  autovideosink sync=false

Windows (PowerShell)

gst-launch-1.0 -v `
  udpsrc port=5000 caps="application/x-rtp,encoding-name=JPEG,payload=26" ! `
  rtpjpegdepay ! `
  jpegdec ! `
  videoconvert ! `
  autovideosink sync=false

Pipeline explanation

udpsrc – receives RTP packets
rtpjpegdepay – extracts MJPEG frames
jpegdec – decodes JPEG video
autovideosink – displays the video on the PC

TLV EEPROM Support

RZ/V2N SoMs are being programmed with identifying information such as the product name, MAC Address and SKUs to allow for programmatic identification of hardware.

Bootloader Firmware Flashing (BL2 + FIP)

The SD card image only contains the Linux kernel and root filesystem. The bootloader firmware — BL2 (Trusted Firmware-A first stage) and FIP (U-Boot + BL31) — must be programmed separately to either SPI NOR flash or the eMMC boot partition.

Flashing Methods

The Firmware Flashing Guide covers three methods for programming the bootloader:

Serial Flash Writer

Initial programming or recovery — board boots via SCIF in Serial Downloader mode

U-Boot CLI

Field updates from a USB drive — no host PC connection required

Linux

In-system updates from a running Linux image via MTD (SPI NOR) or mmcblk0boot0 (eMMC)

Each method supports both SPI NOR flash and eMMC boot storage. See the full guide for step-by-step commands, flash memory layout, and DIP switch (S5) boot mode settings.
