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)

uSD

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]).

Booting from uSD card

Set the Boot Switch to uSD Boot Mode

Here is the correct DIP switch position for uSD boot:

Note: The black rectangle represents the switch position. The unit comes with a pre-programmed bootloader on the eMMC.

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

Downloading the Yocto image

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

https://solid-run-images.sos-de-fra-1.exo.io/RZ/Yocto/vlp4/2026-07-07_adfb4ad/rzv2l-sr-som/core-image-full-cmdline-rzv2l-sr-som.rootfs.wic.gz

For more Yocto 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-rzv2l-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 USB Type-C 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.

TLV EEPROM Support

RZ/V2L SoMs are being programmed with identifying information such as the product name, MAC Address and SKUs to allow for programmatic identification of hardware.
