Please note that on the JNX30-LC each camera connector uses its own I2C bus. This setup is different
from the NVIDIA dev kit. If you like to use CSI-2 cameras, please install the Auvidea BSP (firmware).
This CSI-2 connector has the same 22 pin pinout as the 22-pin connector on the Raspberry Pi Zero
and Raspberry Pi compute module dev kit board. With adapter cable it may connect to Raspberry Pi
camera 2.1 and Vision Component camera modules. Alvium cameras require the Alvium adapter.
Pin 6: by default, the device tree puts a PWM signal on pin 206 (LCD_BL_PWM - GPIO_07). For most
cameras (like Raspberry Pi camera with iMX219 sensor) this needs to be changed to a constant low
output to send a high to the camera for power enable. This is part of the device tree changes.
Some Vision Component camera modules use this pin to synchronise multiple cameras. The pin 5s of
all CSI-2 connectors are OR ‘red together and drive the CAM LED output.
