: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.

:2. Connect Typea computer that will be used to load the eMMC to the USB C port on the CM4-C OTG with a M2 board. The computer will provide both power and data to the CM4. (Type-A to Type-C OTG cable need to your computerbe purchased seperately)
:3. Power the device via PWR TypeThen rerfer to [https://www.jeffgeerling.com/blog/2020/how-C with your 5V Power adaperflash-raspberry-pi-os-compute-module-4-emmc-usbboot this tutorial] to flash raspberry pi OS
:4. Then rerfer to [https://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 OTG after flashing is complete, then restart your device;
:'''PS：If you use CM4 with eMMC, then SD card cannot be used.'''
===3. Preconfigure Device for CM4===
====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.
: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:
:PS: This step is optional, you can also enable ssh through the <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.
:Create a new file named wpa-supplicant.conf that contains the following:
