Watchdog (WD) timer and CSI connection
SW1: Watchdog or CSI can be switched by selecting GPIO44,45. Watchdog (WD) and CSI
cannot be used at the same time. When WD is selected, GPIO44 and 45 are for WDoperation. In addition, when SW3: No.1 of protection SW is off, the reset is forcibly disabled.
When CSI is selected, GPIO44 and 45 are used as i2c for CSI.

Software

The CM4's onboard eMMC will be the boot device for this unit. Booting from an SSD is also
possible. microSD slot is not for system boot. Turn on the eMMC write switch, connect theUSB cable, and use the rpiboot program to read and write images. In addition, thisThe USB port is an eMMC write-only port.
