LC-PI-1103

Product Name

RV1103 Mini Linux Development Board RISC-V Visual Artificial Intelligence with Mesh Port

About

The LC RV1103 mini Linux development board is developed based on the Rockchip RV1103 chip Supports ETH interface, SPI Flash memory, SD card slot.Supports SPI NAND FLASH image burning and SD card image burning. The development board supports multiple interfaces, including GPIO and UART,SPI, I2C, USB, etc. are convenient for developers to quickly develop and debug. The module supports USB recognition and burns image files through a USB data cable

Functional Features

Single core ARM Cortex-A7 32-bit core, integrated with NEON and FPU
Built in Rockchip Micro's self-developed 4th generation NPU with high computational accuracy, supporting int4, in8, and int16

Hybrid quantization, where int8 has a computing power of 0.5 TOPS and int4 has a computing power of up to 1 OTOPS support C. Multiple development environments such as C++, Micro Python, Arduino, etc

Supports multiple interfaces such as GPIO, UART, SPI, I2C, USB, etc. for easy development and debugging
Design with built-in RISC V MCU, supporting low-power fast startup and 250ms fast speed

Capture the image and load the AI model library simultaneously, which can achieve facial recognition within 1 second

Integrated with built-in POR, audio codec, and MAC PHY

Instructions for use

1. Installing Drivers

Open the Rockchip Micro Driver Assistant Driver Install and install the USB driver for this computer

This process does not require connecting to the development board. After installation, restart the computer

2. Using SPI NAND FLASH to mirror burn

Open the Rockchip Micro Tool Kit SocToolKit, select the "RV1103" chip, and then press Connect to the computer after pressing the BOOT button, then release the BOOT button, and the Ruixin Micro Brush Tool will activate

Display USB devices

Click on "Search Path", select the directory where the image file is stored, reload the env file, check all options, click Download, and wait for the download to complete
Attention: Before burning, it is recommended to close security software such as 360 and open the burning tool in administrator mode to prevent burning failure; If LBA fails or Read flash occurs

ID Fail and other situations, please use Windows 7 system for image burning

3. Use Micro SD card to mirror burn
The method of burning a Micro SD card image is similar to that of Flash. Open it
SocToolKit， Select the 'SD Card Tool', format the SD card, install it in the card reader, and connect it to the computer. The SD card size will be displayed on the USB disk. If it is not displayed, please try again.Insert and unplug the card reader, select "SD Boot", choose the boot file (where the update.img file is not required)
Finally, click "Create SD", wait for the creation to complete, place the SD into the development board slot, and power on for testing
Attention: The development board will prioritize booting from Flash mode, so it is not recommended to install Flash memory when using SD card mode

4. ETH Network Port Test
Insert the Ethernet cable into the Ethernet port and connect the UART pins (RX-TX) of the development board using a USB to TTL module; TX--RX；GND--GND）； Open the serial debugging assistant, power on the development board, and then string Output a long string of startup information, and when login: appears, send the username "root"< When Password: appears, send the password "luckbox" to successfully log in Then use the 'ifconfig' command to view the IP
Eth0 displays the IP address of the network port; Usb0 is the IP of RNDIS

5. CSI Camera Test
Connect the camera and ensure it is properly connected before turning it on. The system will automatically recognize the camera
Install VLC media player and open the software, then go to Media ->Open Network Streaming,
Enter the IP address of the network port you just viewed: rtsp://192.168.0.158/live/0
Click play to see the camera image, and you can rotate the lens to focus
