Changes

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.

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.

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:

Now when the Pi starts up SSH will automatically be enabled!

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.
