Lightcrafter FPGA

Nishaanthan Nadarajah
Prodigy 70 points


HI; 
I have worked on lightcrafter and I am trying to understand its operations further. We would like to find out further details on its operations which are not available online or in the manual. 
Therefore, I am wondering if you would be able to help us by providing the info for the questions below.
Thank you.

1. FPGA is typically programmed via JTAG chain, according to the documentation, the Cyclone IV should be programmed via I2C, Can you please provide any documentation in details how to set it up? Do we need any other firmware installed before programming?

2. Can we get the pin assignment file (.sdc file) for the FPGA pin configuration on board?

3. Is it possible to get the source code for current FPGA design on board ( RTL code is highly preferred).

4. Can we get any other reference design in HDL code?

If there are related materials available online, can you please provide links for those? 

We would really appreciate if you could help us by providing the details.

Thank you.

    Hello Nishan,

    #1.

    For FPGA functionality you can look into the FPGA Overview document http://www.ti.com/lit/an/dlpa042/dlpa042.pdf 

    I2C Programmed reference - This is basically used by DM365 to configure the FPGA into various modes, as far as programming is concerned, DM365 has access to FPGA SPI flash where it will update the configuration file. 

    We have released FPGA code only in the binary format. The source code is not available for public uses. The main reason for FPGA on the LightCrafter to do two basic functionality, muxing two video ports (external HDMI and Video Port of DM365). We are not sure customer using this particular design outside for something else.  

    #2. Pin usage you can find from the System Board Schematics. Providing .sdc file we will have to look. 

    #3. Unfortunately no.

    #4. The FPGA Overview document shows the functional design of the chip. That is the maximum available. 

    Regards,
