===Flash OS into the micro SD cardInstallation Video===For NASPi CM4-2.5 and NASPi CM4-M2: https://youtu.be/lXBK5-GFQ48{{#ev:youtube|https://youtu.be/lXBK5-GFQ48}}
A minimum 16 Gb class 10 memory card is recommendedPlease follow the steps below
Please refer ===Flash OS Image===Due to [https://wwwCM4 has a version with eMMC, micro SD card is optional.raspberrypi.com/documentation/computers/getting-startedIf you are using the CM4 with eMMC, you don't need to buy a extra Micro SD card.html#installing-the-operating-system Official installation tutorial]
In fact, you can falsh You flash the OS image into the eMMC if you use the CM4 '''with eMMC''', refer different media according to the following step, thus you don't need purchase the Micro SD cardyour own situation.
====1. Flash OS into the eMMC of CM4 (CM4 with eMMC)micro SD card====:A minimum 16 Gb class 10 memory card is recommended.
1. Short OTG Pin, :Please refer to [https://www.raspberrypi.com/documentation/computers/getting-started.html#installing-the picture below.-operating-system Official installation tutorial]

2:1. Connect Type-C Short OTG with a Type-A Pin, refer to Type-C cable to your computerthe picture below.

:'''PS：If you use CM4 with eMMC, then SD card cannot be used.''' ===3. Preconfigure Device for CM4===Now we think you have successfully flashed the OS to the storage media (mciro sd card or eMMC of CM4). If you attempt to boot now you will not have working USB ports, ssh, or any wireless configuration, so do not remove your SD card, proceed as follows.
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.
====3.1 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.
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=host
:After adding this line the two USB ports (as well as the “External USB” header) will function the next time the CM4 boots.
====3.2 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:
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: touch ssh
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)
in :Now when the root folder of the “boot” volume (the top-most folder of the drive where start4x.elf, fixup.dat and those files are located)Pi starts up SSH will automatically be enabled!
Now when :PS: This step is optional, you can also enable ssh through the Pi starts up SSH will automatically be enabled!<code>raspi-config</code> program after the device boot
====3.3 Preconfigure WiFi / Wireless(Optional)====:You can also preconfigure the Compute Module 4 (and any Pi) by creating wpa-supplicant.conf at the base of the “boot” volume like we did with “ssh” file. In fact, you can setup your wifi after you boot up.
You can also preconfigure the Compute Module 4 (and any Pi) by creating wpa-supplicant.conf at the base of the “boot” volume like we did with “ssh” file. :Create a new file named wpa-supplicant.conf that contains the following:
<pre>
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
Then you can insert your micro sd card into the device & power on it.
===Power management & safe shutdown script installation===
Refer to [[XScript]]
===4. Installing script===After the device is reboot, install the following script to get safe and software shutdown function: refer to [[XScript]] ===5. Enable OLED display===Refer to [[How to flash enable OLED display]] ===6. Flash OS onto into the NVME SSD（Optional）===
Load OS into ssd and you can get extremely fast running speed, you need to refer to the above steps to flash the OS into the Micro SD card firstly, then insrt 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 the ssd as shown in the figure below.
Click '''Start''' to run. Then shut down, unplug the SD card, and restart the device.
