FPGA FMC 4x MIPI CSI Camera, MIPI DSI Display Breakout Adapter , V4L2 Linux Media Pipeline Ultrascale+

Prototyping with advanced FPGA boards is quite challenging, As they often have very high density connectors for expansions and peripherals. As with case with most Modern Systems Xilinx and many other vendors also have very High density very high speed connectors. On Xilinx FPGA have High speed connectors called FMC Connectors. These connectors allow users to attach high speed peripherals to FPGA board.

FMC Connectors also have few types, There FMC HPC connector which has all the pins of HPC connector , While there is a FMC LPC connector which has only a subset of HPC connector. Both FMC HPC and LPC connectors are basically same in terms of mechanical dimensions, They both fit into one another. Its just LPC has few electrical pins. The there is also a even bigger connector even with more pins called Vita 57.4 FMC+ , it is mostly Common with very expensive high end boards

One of the most common peripheral that you can connect to these board is MIPI CSI-2 Camera or MIPI Display. So i decide to make a breakout board for MIPI CSI, There are 4x Powered , 4 Lane MIPI Connectors that support both camera and display.

This Board Has 4x 22Pin 0.5mm Pitch 4Lane MIPI Camera Connector, Same As Raspberry Pi 5 onwards,

Compatible to all Raspberry Style Cameras, 2 Lane and 4Lane cameras both

Compatible Standard 2Lane Rapsberry Pi 15Pins 1mm Pitch Cameras using RPI to Mini FPC Cable

Compatible to Digilent PCam cameras

Pin Assignment

Pin assignment is very critical with every FPGA board it's also similarly critical with the on both ZCU102 and ZCU106. It Comes down to that ZCU106 only supports MIPI RX on very limited number of Pins even though MIPI TX is supported on quite a few pins. But input pins are very few and very limited number of banks as well so only the bank number 28 64 65 66 67 and 68 are available directly on the ZCU106 HPC connectors which can be used for MIPI input and even on those banks bank you get very limited pins which can be used as a clock Lane and again they are specific Pins which can be used as a data aim when you are using specific clock pins
