VisionFive 2

Descriptions

VisionFive 2 is the world’s first high-performance RISC-V single board computer (SBC) with an integrated GPU. Compared with its last generation, VisionFive 2 has been fully upgraded with significant improvements in the processor work frequency, multimedia processing capabilities, scalability, etc. Its superior performance and reasonable price make VisionFive 2 the best affordable RISC-V development board ever.

Note:
Each GPIO pin can safely draw a maximum current of 32 mA, whereas the maximum current draw when all GPIOs are combined should be less than 100 mA. Please take this into account or otherwise, you will end up destroying the GPIO pins.
All GPIOs can be configured to support different functions including but not limited to SDIO, Audio, SPI, I2C, UART, and PWM. For the instructions, refer to the VisionFive 2 40-Pin GPIO Header User Guide.

Getting Start

Required Hardware

Make sure you have prepared the following hardware items:

  • VisionFive 2
  • Micro-SD card (32 GB or more)
  • PC with Linux/ Windows/ MacOS
  • USB to Serial Converter
  • Ethernet cable
  • Power adapter
  • USB Type-C cable
 Note:
During the use of VisionFive 2, avoid contact with hard objects that may cause damage. Thus, StarFive recommends that you use spacers for the following NPTHs (Non Plating Through Hole):

Boot mode settings

VisionFive 2 provides pins to determine the boot mode before it is powered up. The following are the available boot modes and details.

Flashing OS to a Micro-SD card

Now we need to burn Debian (which is a Linux distribution) to a micro-SD card so that it can run on the VisionFive 2. This chapter provides example steps to flash Debian to a Micro-SD card with Linux or Windows.

Flashing with Linux or Windows

To flash the image with Linux or Windows, perform the following steps:

  • Insert a micro-SD card into the computer through a micro-SD card reader, or by a built-in card reader on a laptop.
  • Download the latest Debian image from: [ https://debian.starfivetech.com/ ]
  • Extract the .bz2 file.
  • Visit [ https://www.balena.io/etcher/ ] to download BalenaEtcher. We will use BalenaEtcher software to flash the Debian image to a micro-SD card.
  • Install BalenaEtcher and open it.

  • Click Flash from file and select the location of the image where we just unzipped the following file:

starfive-jh7110-VF2-<Version>.img 

Tip:
<Version> indicates the version number of the Debian image.
  • Click Select target and select the connected micro-SD card.
  • Click Flash! to start the flash task.

Logging into Debian

Perform the following steps to log into Debian: 

Tip:
StarFive recommends that you use SD card or eMMC mode since the versions of SPL and U-Boot in the QSPI flash may be outdated and require update.
  • Insert the TF card with the Debian image into VisionFive 2 and power it on.
  • Enter the credentials as follows:
Username: user
Password: starfive

You can log into Debian OS by: 

Tip:
If you need to load different DTB files, update the ./boot/uEnv.txt file as described in the Step 6 under Adding New File section in the VisionFive 2 Single Board Computer Software Technical Reference Manual. [ https://doc-en.rvspace.org/VisionFive2/SWTRM/index.html ]
