Parameters

User Guide

As the Debian image is large, it is recommended to use a TF card of 32GB or above.

Install Debian System

Download, open SDFormatter, and format the corresponding TF card.

Download, open Win32DiskImager.zip, choose the corresponding image and disk, and click "write".

Booting

Turn the two DIP switches on the board to the right (ON) position.

Insert the TF card that burned the image, connect the USB to TTL module according to the figure, connect it to the PC, and check the port. 

Open MobaXterm and operate as shown below:



Access network cable and power supply.

Enter the following command (to be entered line by line):

ext4load mmc 1:3 a0000000 /boot/uEnv.txt
env import a0000000 17c
setenv fdtfile starfive/jh7110-visionfive-v2.dtb
sysboot mmc 1:3 ext2 b0000000 /boot/extlinux/extlinux.conf

Wait a few seconds and it will automatically enter the system (if you have selected it before, you must select it before entering the system).

Enter the corresponding account and password:
Username: root
Password: starfive

Connect To SSH

The Debian system of VisionFive2 does not support the root user to use an ssh connection, so it needs to be set according to the following configuration.

nano /etc/ssh/sshd_config

Add the following two sentences at the end of the file:

PasswordAuthentication yes 
PermitRootLogin yes

Save, exit, and restart the ssh service.
service sshd restart or systemctl restart sshd.service Use MobaXterm software to ssh connection to VisionFive2, if the connection fails, restart VisionFive2.

How To Use With Other Product

WM8960

Replace the command at startup with the following:

ext4load mmc 1:3 a0000000 /boot/uEnv.txt 
env import a0000000 17c
setenv fdtfile starfive/jh7110-visionfive-v2-wm8960.dtb 
sysboot mmc 1:3 ext2 b0000000 /boot/extlinux/extlinux.conf

Install alsa-utils

apt install alsa-utils

If the module is not connected at the beginning, you need to restart VisionFive2 to detect the audio device.
Type aplay -l to list sound cards and digital audio devices.
Pay attention to the position marked on the picture, which indicates the device number of the sound card and digital audio equipment, where card0 and device0 are the headphone jacks on the VisionFive2 motherboard, card0 and device2 are the headphone jacks on the WM8960 module.

Type arecord -l to list sound cards and recording devices.
Pay attention to the position marked on the picture, which indicates the device number of the sound card and recording device, card0 and device1 are the two patch microphones on the WM8960 module.

Enter the command:

arecord -Dhw:0,1 -f S32_LE -r16000 -c2 -d 10 -t wav sound_32b_16k.wav

Start recording 10 seconds of 32-bit, 16kHz audio, and save it in the current directory, the file name is sound_32b_16k.wav.
input the command:

aplay -Dhw:0,2 -f S32_LE -r16000 -t wav sound_32b_16k.wav

Use the WM8960 module onboard headphone interface to play audio.
