Im trying to add support for RPI cameras on my FPGA board but Im confused on a few things.
1. Why do new Raspberry Pis use 22 pin connectors and cables while all cameras use 15. It looks like they are the same pins just spread out on 22 pins.
2. As far as I understand the camera GPIO and I2C voltages are 3.3V and the camera itself converts the 3.3V to 1.8V for I2C (please confirm this).
3. On some schematics, there is GPIO CLK missing, on another schematic pull up resistors on the I2C lines are missing. Do I add GPIO CLK and pull ups in my design?
4. I have seen people using cams v1.3 and v2 on the Zynqberry, can I presume that cam v3 will also work? As far as I understand they all have the same pinouts and the only real difference is the need for higher performance to drive v3 which Zynqberry/my board should have.
If anyone has implemented MIPI D-PHY for Zynq 7000 (XAPP894) to be used specifically with Raspberry Cameras please let me know.
