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 WD
operation. 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.

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