1. Edit /boot/config.txt (sudo permission required).:<pre>sudo nano /boot/firmware/config.txt</pre>:Add the following content:: <pre>dtoverlay=tc358743</pre> :If your modules [[C790]] support audio, add the following content to enable audio support. If you use [[C779]], please ignore this step: <pre>dtoverlay=tc358743-audio</pre> : If (and only if) you have a device such as the C790 that supports the 22pin connector with all 4 lanes wired out, and are using a Compute Module with the CAM1 connector that also has all 4 lanes wired up, you can use:: <pre>dtoverlay=tc358743,4lane=1</pre> : Then '''reboot''' the raspberry Pi board, '''this is very important!DON'T miss this step!''': <pre>sudo reboot</pre> :After adding the driver configuration, restart the Raspberry Pi for it to take effect. If the configuration is correct, execute '''ls /dev/video*''' in the terminal, and you should see video devices listed::<pre>ls /dev/video1</pre>:<pre>/dev/video1</pre> 2. Execute the following command to find the '''media node''' corresponding to the CSI as '''media0''', under the '''rp1-cfe (platform: 1f00128000.csi)''' field:<syntaxhighlight lang="python" line highlight="24,33">blikvm@blikvm:~ $ v4l2-ctl --list-devicespispbe (platform:1000880000.pisp_be): /dev/video20 /dev/video21 /dev/video22 /dev/video23 /dev/video24 /dev/video25 /dev/video26 /dev/video27 /dev/video28 /dev/video29 /dev/video30 /dev/video31 /dev/video32 /dev/video33 /dev/video34 /dev/video35 /dev/video36 /dev/video37 /dev/media1 /dev/media2 rp1-cfe (platform:1f00128000.csi): /dev/video0 /dev/video1 /dev/video2 /dev/video3 /dev/video4 /dev/video5 /dev/video6 /dev/video7 /dev/media0 rpivid (platform:rpivid): /dev/video19 /dev/media3</syntaxhighlight>'''PS''': Please remember '''the media number''' in line 33. The following commands must use the same media number. 3. Locate the node corresponding to tc358743 as v4l-subdev2, and the pad0 of rp1-cfe-csi2_ch0 as video0: :Note: The '''/dev/media0''' here comes from the media number obtained in the previous step. media-ctl -d /dev/media0 -p 4. To query the current input source information, if the resolution displays as 0, it indicates that no input source signal has been detected. In this case, you should check the hardware connections and follow the steps mentioned above refer to troubleshoot.: v4l2-ctl -d /dev/v4l-subdev2 --query-dv-timings<syntaxhighlight lang="python" line highlight="2-3,8">blikvm@blikvm:~ $ v4l2-ctl -d /dev/v4l-subdev2 --query-dv-timings Active width: 1920 Active height: 1080 Total width: 2750 Total height: 1125 Frame format: progressive Polarities: -vsync -hsync Pixelclock: 74250000 Hz (24.00 frames per second) Horizontal frontporch: 0 Horizontal sync: 830 Horizontal backporch: 0 Vertical frontporch: 0 Vertical sync: 45 Vertical backporch: 0 Standards: Flags:</syntaxhighlight>5. Confirm the current input source information. v4l2-ctl -d /dev/v4l-subdev2 --set-dv-bt-timings query[[File:X1300v1.0-setting5.png]X1300 Software] 6. Initialize media0. media-ctl -d /dev/media0 -rNote: The '''/dev/media0''' here comes from the media number obtained in the '''step 2'''. 7. Connect CSI2's pad4 to rp1-cfe-csi2_ch0's pad0.<pre>media-ctl -d /dev/media0 -l ''\''csi2'\'':4 -> '\''rp1-cfe-csi2_ch0'\'':0 [1]'</pre> 8. Configure the media node.<pre>media-ctl -d /dev/media0 -V ''\''csi2'\'':0 [fmt:RGB888_1X24/1920x1080 field:none colorspace:srgb]'media-ctl -d /dev/media0 -V ''\''csi2'\'':4 [fmt:RGB888_1X24/1920x1080 field:none colorspace:srgb]'</pre>Note: The '''/dev/media0''' here comes from the media number obtained in the '''step 2'''. 9. Set the output format. v4l2-ctl -v width=1920,height=1080,pixelformat=RGB3 10. Capture two frames for testing to verify if tc358743 is functioning properly. Other methods, such as using GStreamer, are not currently available. 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=hdmiin.yuv --stream-poll 11. If you have installed a desktop version of Raspberry Pi, you can use ffplay to directly play YUV files. ffplay -f rawvideo -video_size 1920x1080 -pixel_format bgr24 hdmiin.yuv On a Windows computer, you can use software like 7yuv to view .yuv files. For the tutorial with an input format of 19201080, you should select BGR888 in the top right corner of 7yuv and set the resolution to 19201080 to view the two frames you just captured.
