5. Installing Operating System
5.1 For Raspberry Pi CM4 with eMMC
If your Raspberry Pi Compute Module has eMMC, you can flash the OS into its eMMC. If you want,
you can have this done with the official I/O board. However using the official I/O board is not
necessary because you can get this done on PiGear Nano board directly.
Before proceeding, please make sure to short the "bypass power switch" jumper. This is to bypass
the e-latch power switch, so your PiGear Nano board will be powered even without the operating
system. The "bypass switch" jumper is on the left of Raspberry Pi CM4 (above the "Default On"
jumper), as shown in picture below:
You will also need to short the "Disable eMMC Boot" jumper, so the eMMC on your Raspberry Pi
CM4 will boot in USB mass storage mode, and you can flash the disk image into it.
Now connect a USB Type-C cable to PiGear Nano, and connect the other end of the cable to your
computer. This USB cable will power your PiGear Nano during the installation process, and there is
no need to connect any other power supply.
