I’m attempting to create a custom Xavier NX carrier board, on my board I wish to have 6 synchronised, 2Lane CSI camera inputs.
My intended camera module will be a Global shutter camera (hence will have a external trigger pin) with MIPI CSI-2 15pin (probably ArduCam OV9281 1MP Global Shutter Camera).
Looking at my options to achieve this I’m a bit confused over the control pin requirements.
1# Master Clocks for each camera module - Should I be using a single source (boosted) and connected to all 6 cameras? If not how should I configure them from the 4 available?
2# PWDN pins - I only see 2 available, again can these just be connected to multiple camera modules or do I choose GPIO pins for the remaining 4 cameras?
3# My camera modules will have a trigger pin, I was intending firing this in all modules simultaneously via a GPIO.
However is it another possible solution to fire synchronised trigger events via the I2C bus (presuming appropriate connections to talk to all camera modules via I2C simultaneously)?
As you might have guessed I’m a bit of a weekend warrior with this (i.e. I’m more used to Arduino type circuits & in over my head:)
I have read the product design guide and the camera specific guide, But am still just as lost!
