To use ==Installing the HDMI to CSI-2 bridge, you will need to enable '''Enable legacy camera support'''. Operating System==

Open a terminal window and type === Flash OS onto the following commandMicro SD card (CM4 '''without''' eMMC)===Please refer to [https: //www.raspberrypi.com/documentation/computers/getting-started.html#installing-the-operating-system Official installation tutorial] sudo raspi-config=== Flash OS onto the NVME SSD===Then use You need to refer to the cursor keys above steps to scroll down flash the OS into the Micro SD card, then insert the Micro SD card, turn on the device, and then click '''Applications''' =>'''Accessories''' =>'''SD Card Copier''', run the '''SD Card Copier''' program, and copy the OS to "Interface Options"the NVME ssd as shown in the figure below.

Press Click '''Start''' to run. Then shut down, unplug the ‘Enter’ keySD card, and restart the device.

3. Power the device via PWR Type-C with your 5V Power adaper 4. Then rerfer to [[Filehttps://www.jeffgeerling.com/blog/2020/how-flash-raspberry-pi-os-compute-module-4-emmc-usbboot this tutorial] to flash raspberry pi OS 5. Remove the jumper of '''nBoot''' after flashing is complete, then continue the following steps; PS：If you use CM4 with eMMC, then SD card cannot be used. ==Preconfigure X635Device for CM4== If you attempt to boot now you will not have working USB ports, ssh, or any wireless configuration. We can preconfigure your CM4 device by plugging mico sd via sd reader into a windows computer / Pi. You should see the “boot” volume where we can preconfigure our CM4 to be working right from the start. ===Enable USB Ports=== When mounted in the IO board the USB ports will not function without making a change to config.txt and adding an overlay. Add the following line to config.txt: dtoverlay=dwc2,dr_mode=hostAfter adding this line the two USB ports (as well as the “External USB” header) will function the next time the CM4 boots. ===Enable SSH=== It's very useful to have SSH enabled when working with the Compute Module 4. It is enabled simply by creating an empty file named:  ssh in the root folder of the “boot” volume (the top-most folder of the drive where start4x.elf, fixup.dat and those files are located) Now when the Pi starts up SSH will automatically be enabled! ===Preconfigure WiFi / Wireless=== You can also preconfigure the Compute Module 4 (and any Pi) by creating wpa-softwaresupplicant.conf at the base of the “boot” volume like we did with “ssh” file. Create a new file named wpa-12supplicant.conf that contains the following:<pre>ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevcountry=USupdate_config=1 network={ ssid="YourNetwork" psk="YourPassword"}</pre>When this file is created in the base of the “boot” volume it will automatically be applied to the Pi upon the next startup. Make sure to adjust your country=US line to your own country as this can impact what channels and functionality are available from your WiFi card! Then you can insert your micro sd card into the X635 & power on it.png ==Enable legacy camera support==After you power on the x635, to use the HDMI to CSI-2 bridge, you will need to [[How to enable camera support in Raspberry Pi OS|700pxEnable legacy camera support]] ==Download dt-blob.bin File==Run the following command: sudo wget https://datasheets.raspberrypi.org/cmio/dt-blob-cam1.bin -O /boot/dt-blob.bin Then reboot for the dt-blob.bin file to be read. sudo reboot ==Check HDMI to CSI-2 bridge==Open the Terminal and run the command to check if the HDMI to CSI-2 bridge is being seen by the operating system.

Note: You should get back <big>supported=1, detected=1</big>, indicating that the CSI-2 bridge is detected and supported by the operating system. If you get detected=0, then the CSI-2 bridge is not being seen by the operating system. ==Test x635 shield via command line== ===Connect the HDMI source device===Before testing the X635, you must connect your HDMI signal source device into [[X635]] as the HDMI in HDMI to CSI-2 bridge with mini HDMI to HDMI wire.  <big>IMPORTANT! The HDMI to CSI-2 bridge only accepts HDMI input: 1080p30, 1080p25, 720p30, 720p25</big> ===Picture test===Record a sample picture: open a terminal window and run the following command to take a still picture and save it to the Desktop: raspistill -o Desktop/image.jpg When the command runs, you can see the camera preview open for five seconds before a still picture is taken. ===Video test===Record a sample video using the following raspivid command: raspivid -o Desktop/video.h264[[File:X635-software-18.png|700px]] In order to play the video file, double-click the video.h264 file icon on the Desktop to open it in VLC Media Player. ==Advanced application==* Install GStreamer on CM4 - <big>For advanced programmers and advanced applicaitons</big>* Check out this link - https://qengineering.eu/install-gstreamer-1.18-on-raspberry-pi-4.html * GStreamer official website: https://gstreamer.freedesktop.org/   Or refer to http://www.suptronics.com/miniPCkits/x635-software.html  Return to [[X635]]
