VHDL code for using LVDS lines of Xilinx FPGA for MIPI CSI-2 TX protocol. The goal is to support sending video or any other data using FPGA that don't have a dedicated D-PHY compatible outputs. (HS and LP outputs modes). The rate is 800Mbit/Sec per lane, two lanes total + DDR clock. The code was tested and works as expected on KC705 evaluation board. The custom PCB board was also developed, and available in this repo: https://github.com/VideoGPU/FMC_MIPI The board connects between KC705 FMC and a camera connector of Jetson TX2. Customisation for other boards is straightforward. VHDL code ~fully duplicates the behaviour of the camera board shipped with Jetson TX2 development kit. I2C slave code is from https://github.com/tirfil/VhdI2CSlave repo.

For educational purposes.

1.Clone the repo

git clone [email protected]:VideoGPU/MIPI_CSI2_TX.git

2.Inside Vivado Tcl console,navigate to the repo dir. In my case it was

cd /home/videogpu/MIPI_CSI2_TX

3.Run the installation script:

source csi_tx.tcl

It will create a ready to use project for Kintex-7 KC705 evaluation board. Now you can generate a bitstream, or run the simulation.

Terminal output: Example output: The vertical line position in magenta strip indicates a frame number

The whole setup:

Interconnector board:
