[BUG] Unable to access to 4 TOFs from 4 S5K33D through OAK-FFC-4P

[Thinkminator]

I have purchased a Luxonis OAK-FFC 4P and 4 S5K33D recently, and the goal is to view TOFs from 4 cameras at the same time. However, if I run the command $python3 cam_test.py --cameras cama,t camb,t camc,t camd,t, I am only getting tof from cama, and the thing crashed in 2s.

Then, I try with something lighter which is to access only the color views from all 4 cameras concurrently by running $ python3 cam_test.py --cameras cama,c camb,c camc,c camd,c. This time, no error is received, but only 2 views from cama and camd are shown (which are the MIPI 4 lanes).

However, if I unplug 1 camera from MIPI 2 lane, then 3 cameras will be supported for color view. Therefore, I am wondering, is it possible for us to view 4 tofs through OAK-FFC 4P concurrently, if so are there any additional steps that need to be taken, also is it also feasible for OAK-FFC 4P PoE?

Thank you very much.
