FPGA development board with MIPI

[learnfromfailures]

 I searched online for a less expensive dev board that can have MIPI CSI-2 to USB 3.0 functionality with Xilinx FPGA. Most of the development boards start at $275 or up. I thought I should build one since I have an FPGA board design background. I'm planning to keep the cost close to $100. So far with the HW it is a feasible target. The board will also have I2C, SPI, UART ports, and other GPIOs. I needed this board for my project but happy to release it in the public domain. I'm not sure if I should add more features that can make it into a more generic development board. Any thoughts?

start with the obvious need,  and when you have a working prototype, add 1 feature at the time ... 

when you add too many things at once, your coding may become a mess and new stuff may or could break the other ...
and for sure it may or could go beyond your target pricing

my 2 cents

Is there any point to have such board if Infineon/Cypress EZ-USB CX3 exists and also a devkit?

This is solely for cost purposes? So you will deliver a working FPGA image for this? Or we will need to do it ourselves just to save $299-$100=$199?

what's the main reason for the cost limit ?
help me understand. I might be able to recommend something more appropriate.

A big xilinx dev board is only $2000.
Otherwise, I would suggest a MIPI M or J 484 board for a Ti180 from Efinix, about USD800 I think. cheap.  and good .

There are so many development boards out there. I didn't find any with Spartan 7, USB-c 3.0, and mipi interface close to the 100-dollar range. Something like these boards
1)  https://shop.ztex.de/product_info.php?products_id=102 (this one cost around 500 Euro)
2)  https://www2.hdl.co.jp/en/ft600-series-m/edx-009-m1.html (1000 USD)

Needed it for my own project but I'm happy to release it in the public domain. The low cost was natural since I'm not using CX3 chip. I will pick an external Camera module (5-12 megapixels) that can be purchased separately. 

So you will deliver a working FPGA image for this? Or we will need to do it ourselves just to save $299-$100=$199?

I will deliver the FPGA config image and for MIPI you can use Vivado DSI IP. For USB 2.0 to JTAG FPGA, I will write code for the FT2232 chip.

I'm on a budget and I can't really go over that for my own project. So I'm trying to keep the board cost close to 100.
