DLPLCRC410EVM: Discovery 4100 is not connected problem

Hello Suhyun,

This is odd, because the GUI window shows that a 0.7 XGA is attached.  That means that it read that information from the controller board after the DLPC410 detected the DMD. 

Is this one of the newer DLPLCRC410EVM controller boards?  Please send a picture of the top of the controller board (the side with the FPGAs).

Fizix

This is the board when it is connected! Thank you.

Hello Suhyun,

Thank you for the image.  This is a version of the board that has XCF16 PROM chips.  It should work fine 

Can you try running the Help/About and report the versions it shows there.

Mine is not showing board information because I do not have an EVM plugged in.

Fizix

I don't think mine shows anything as well.

ChatGPT tells me that my FPGA is empty so it recommends the step below. Do you think this is a good solution? I am new to this H/W setup so I am not that much expert to this. Could you also give me some advice?

• Prepare a Xilinx JTAG cable

• Recommended: Xilinx Platform Cable USB II

• Obtain the bit/mcs file for the board from TI

• Launch Xilinx iMPACT

• Connect to the FPGA via JTAG

• Load the bit file directly to the FPGA for testing

• Program the mcs file to the Flash for automatic booting

Hello Suhyun, 

Let me work with Fizix on providing the correct bit/mcs file so you can program the FPGA with the appropriate firmware. 

Once you receive the bit/mcs file, you will need to use the Xilinx iMPACT tool to program and load the firmware into the FPGA.

Hello Suhyun,

For some reason your last reply did not show up on my dashboard.

There are decent aftermarket cables now that can be used.

The steps you listed are correct.  You will need download a version of Xilinx Labtools (IMPACT) that support the XCF16 PROMs (ver 14.1 should work).  Do you have access to the MySecure area with the PROM files.  Specifically the APPS_FPGA v2 programming files? 

Fizix

I am confused. Is it common to have empty FPGA and is the process needed or all users who bought this?
Also, is there a guideline for doing these steps (lists that I have got replied by ChatGPT)? I would appreciate the guidelines if it exists. Thank you!

Hello Suhyun,

It is very unusual for it to come empty.  I also noticed that the PROM attached to the LX50 (APPS_FPGA) has a sticker on it.

What are the numbers on that sticker?  In your picture, it is the one below the two FPGAs.  It looks the same as the one for the LX30 (controller FPGA).

If it is in fact the same it would try to configure the LX50 as controller, which would not work and would act similar to being empty.

The PROM should be preloaded with the APPS code, either v1 or v2.  Where did you obtain this board from?

Fizix

The two sticker each says : (1) DLPR410B YVA 22/24 (2) DLPR410A YVA 22/24
I bought it from Mouser Korea.

I should first try to do the steps that I wrote in here. :)
