X1300-v1.0 Software & Configuration
This tutorial assumes you've already set up a Raspberry Pi with Raspbian12 (bookworm). For help installing the Debian-based OS on your Pi, check out the docs on Raspberrypi.org.
1.0 To check the Kernel version, execute the following command:Pi@raspberrypi ~ $
uname -a
1.1 To enable the device tree overlay in the /boot/firmware/config.txt
Pi@raspberrypi ~ $
sudo nano /boot/firmware/config.txt
Add two lines at the end of the file that reads like this:
dtoverlay=tc358743,4lane=1
dtoverlay=tc358743-audio
Save and exit. In nano, you do that by hitting CTRL + X, answering Y, and hitting Enter when prompted.
1.2 Reboot the Raspberry PiPi@raspberrypi ~ $
sudo reboot
1.3 Check video devices listPi@raspberrypi ~ $
v4l2-ctl --list-devices
1.4 Create an EDID txt file to set up the HDMI to CSI adapter before you can connect it to an HDMI source. This EDID file will enable the video and audio mode supported.
Pi@raspberrypi ~ $
sudo nano 1080P60EDID.txt
Copy the below EDID data and paste it to 1080P60EDID.txt

Save to /home/pi and exit. In nano, you do that by hitting CTRL + X, answering Y, and hitting Enter when prompted.
1.5 Loading the EDID dataPi@raspberrypi ~ $
v4l2-ctl -d /dev/v4l-subdev2 --set-edid=file=/home/pi/1080P60EDID.txt --fix-edid-checksums
1.6 Check the screen resolutionPi@raspberrypi ~ $
v4l2-ctl -d /dev/v4l-subdev2 --query-dv-timings
1.7 Applying the screen timing to the capture setup
Pi@raspberrypi ~ $
v4l2-ctl -d /dev/v4l-subdev2 --set-dv-bt-timings query
1.8 Reset linksPi@raspberrypi ~ $
media-ctl -d /dev/media2 -r
Please note that the /dev/media number can change. Go to step 1.3 to check the media number.
1.9 Set formatsPi@raspberrypi ~ $
media-ctl -d /dev/media2 -l 'csi2:4 -> rp1-cfe-csi2_ch0:0 [1]'
media-ctl -d /dev/media2 -V 'csi2:0 [fmt:RGB888_1X24/1920x1080 field:None colorspace:Srgb]'
media-ctl -d /dev/media2 -V 'csi2:4 [fmt:RGB888_1X24/1920x1080 field:None colorspace:Srgb]'
2.0 Set output formatsPi@raspberrypi ~ $
v4l2-ctl -v width=1920,height=1080,pixelformat=RGB3
2.1 Capture frames and save to /home/pi (filename: csitest.yuv)Pi@raspberrypi ~ $
v4l2-ctl --verbose -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat='RGB3' --stream-mmap=4 --stream-skip=3 --stream-count=2 --stream-to=csitest.yuv --stream-poll
2.2 To play the YUV file on Raspberry Pi OS desktop, use FFplay. (Not work if executing the command from SSH).Pi@raspberrypi ~ $
ffplay -f rawvideo -video_size 1920x1080 -pixel_format bgr24 csitest.yuv
