¶ Product parameters
¶ Basic Tutorial
¶ Debian system installation
Download and openSDFormattersoftware,Format the corresponding TF card
Download and openWin32DiskImagersoftware,Select the corresponding image file and disk and click Write
¶ Start
Turn the two dip switches ON the board to the right (ON) position
Insert the TF card with burned image, connect the USB to TTL module according to the figure, connect the USB to TTL module to the PC, and determine the port
Open MobaXterm and follow the illustrated steps
Access network cable and power supply, in U-boot print to the illustrated position to try, press any key to enter the device tree switch
Enter the following command (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
Waiting a few seconds will automatically enter the system (if you have selected it before, you must select it before entering the system).
Username: root
Password: starfive
¶ Extended file system ensures that all storage on the memory card is available
To query the memory space, run df -h
Enter the fdisk /dev/mmcblk1 command
Enter as shown in the figure. Press enter for position 5 and 6
Enter the command resize2fs /dev/mmcblk1p3
Run df -h to check the space size
¶ View the IP address
The net-tools toolkit is not installed on Debian, so you need to install it manually
Use command
apt-get install net-tools
After the installation is complete, run the ifconfig command to view the IP address of the corresponding network port
¶ Connect SSH
VisionFive2's Debian system does not support ssh connections as root, so you need to set this up as follows
Edit the ssh configuration file
nano /etc/ssh/sshd_config
Add the following two sentences at the end of the document:
PasswordAuthentication yes
PermitRootLogin yes
Save the Settings, exit, and restart the ssh service
service sshd restart or systemctl restart sshd.service Use MobaXterm to connect to VisionFive2 over ssh. If the connection fails, restart VisionFive2
¶ Adaption product must be used
¶ WM8960
In U-boot print to the position shown, press any key to enter the device tree switch
Replace the power-on command 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
Enter arecord -l to list sound cards and recording devices
Note the position marked on the figure, which represents the device number of the sound card and recording device. card0, device1 is the two patch microphones onboard module WM8960
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 as sound_32b_16k.wav
Enter the command:
aplay-Dhw :0,2 -f S32_LE-r16000 -t wav sound_32b_16k.wav
Audio is played using the onboard headphone jack of the WM8960 module
Note that the VisionFive2 motherboard onboard headphone jack only supports output audio in 16-bit audio format
