Image burning

1.Install Rpiboot_setup on the system and short the jumper cap to BOOT and GND on the baseboard.
2.Open the Rpiboot_setup program and insert the Type-c cable into the baseboard. At this time, the program will automatically burn and the Raspberry Pi will automatically virtualize the EMMC into a USB flash drive.

3.Use the SDCardFormatter tool to format the virtual USB flash drive.

4.Use win32diskimager to burn the downloaded Raspberry Pi image.

5.After the firmware burning is completed, unplug the Type-C data cable and the jumper caps of BOOT and GND.

Function testing

1.Plug in the USB mouse, USB keyboard, network cable, and HDMI cable to connect to the monitor.CAM1 is inserted into the 15P camera, and DSI1 is inserted into the 15P display screen.It is forbidden to plug or unplug any equipment while the power is on.

2.Plug in the Type-C data cable, power on the Raspberry Pi, and display the startup process through HDMI.For the latest image, you need to set your own username and password after burning it for the first time,and you will automatically log in after subsequent startups.

3.Enter the following command in the Raspberry Pi terminal to open the CAM1 and DSI1 interfaces.

sudo chmod 777 dt-blob-disp1-cam1.dts<br>
sudo  dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob-disp1-cam1.dts<br>
sudo reboot

After restarting, the DSI1 screen can be used. The CAM1 camera needs to be turned on manually and entered in the command line.

sudo raspi-config

Select Interfacing Options->Camera->Yes->Finish-Yes on the display, enable the CAM1 camera, and then restart.
After restarting, check the connected CAM1 camera image:

sudo raspivid -t 0 -cs 0

If you want to re-enable HDMI0, just delete dt-blob.bin.

sudo rm -rf /boot/dt-blob.bin
