About the FPGA on DLP300 EVM

Other Parts Discussed in Thread: DLPC300

Hi,

I would like to reconfigure the FPGA on the LightCrafter EVM (DLP3000). Does anyone know how to do it? It's said you can program via the DM365 on board, but I don't see any documentation in details. I would like to see anything that can help me set up the configuration, pin assignment script for the board or any reference design.

    Hello Jiawei,

    I assuming your question is more from programming your own logic or re-purpose for other logic implementation. If it is, so there is no direct way of using.

    As discussed on FPGA documentation www.ti.com/lit/an/dlpa042/dlpa042.pdf it is used to perform limited functions, there is no plans as on date to release the pinout and other details for the chip. We also intend the FPGA on the board to be used only for programming the logic that is provided in binary (.rbf) format with standard package release. 

    As far as DM365, it helps in programming the configuration file of FPGA flash via SPI bus. The GUI tool can be used to update the configuration file .rbf file.

    Regards,

    Hi Sanjeev ,

    Thank you for your reply. Right now we are developing a design that bypass the FPGA. We just want to directly connect the HDMI to DLPC300. I have some experience on FPGA development. According to the schematic, I might be able to write tcl script for pin assignment (.sdc). But there are several things I need to for sure.

    1. Does any document shows how exactly configure the FPGA via SPI? The GUI you talk about.

    2. Is the default .rbf file available to customers? Where I can get them?

    3. If I write HDL code and generate the bitstream file through Quartus II, is it ready enough to be configured into FPGA?  In other words, the .rbf file is the same with the file generated by Quartus II or not?

    Hello Jiawei,

    #1. With the GUI connected to the Kit, see the snapshot steps to program .rbf file.

    #2. Copy and install the package from here http://www.ti.com/lcrfw3_win

    #3. Although no body stop you from programming your own .rbf file, you should understand that DM365 communicating with the chip via I2C and the various FPGA I/Os are expected to in certain way (you can look at the schematics on which I/O lines are used for what) , so it would be difficult.

    >> We just want to directly connect the HDMI to DLPC300

    From the GUI If you send command to DM365 to switch Display Mode to to HDMI Port, it is essentially configuring the FPGA in bypass mode, so the data from DVI receiver chip to DLPC300 goes as it is unmodified.Is that what you were looking for?

    Regards,
