DLPLCRC410EVM: DLP DISCOVERY 4100 board USB connection problem

Hello Cedric,

From the GUI, while it is displaying DMD: No DMD please open the "About and report the information displayed there.  

Also in your middle picture, just above the 2 FPGAs there is a PROM with a white label on it.  Can you report the information found there?

Fizix

Hello Fizix,

Thank you for your help.
Here are the info we managed to gather on the PROM :

XCF1LP FG

BRT

CK 0U3 V5

CHN 7B 819

I am unsure about some characters since they are very tiny.

If it's needed, I can move the card to a lab where we have microscopes to check again, thought it would be great not have to.

Also, here is a screenshot of the about section.

I think it weird that the dll does not appear. It is currently in the C:\Windows\SysWOW64 folder. Maybe we should copy it to System32 ?

It is also strange that the USB driver doesn't appear either... (We had to turn off the card, since the software will crash with the card turned on).

Thanks for your help,

Best regards,

Cedric

PS : we are also working on very simple C++ code for Visual Studio, based on the API (D4100_usb.dll), to try a very basic connection and gather some infos.

Hello again Cedric,

I was referring to the information on the white label in your initial series of images.

I need the information off of the little white label.  It does not have enough resolution to make it out.

Fizix

Sorry for the misunderstanding.
I assumed you wanted the info under the sticker. I think you can have the full picture by left clicking on the thumbnail (from my original post), then right click on the enlarged picture, then "open the picture in a new tab".
Here are the info nonetheless :

2510442
-0001

We will try the C++ code tomorrow and update the topic with some infos if we find something that we think may be valuable.

Thank you again for your help,

Please let me know how that goes with the C++ code.

Hello Fizix,

Following the instructions given in the DLP Discovery 4100 Development Kit APIProgrammer’s Guide (aka dlpu039.pdf), we are using the D4100_usb.dll since ActiveX is no longer supported by Microsoft.

Using the .dll, we managed to list the functions in it, then we are only trying to check if the card is connected and gather basic informations. To do so we are using the GetNumDev() function, which returns 1 (and 0 when unplugging the card). So far, everything seems to be OK. For the record, we have no other USB devices plugged in, and we are using Visual Studio. We have to compile in 32 bits (x86) to properly load the .dll, otherwize, we get an error. The computer is in Windows 10 64 bits though, which we can't change, due to company policies/IT tech support rules.

However, calling GetDMDTYPE() returns inconsistent results. I tried with both 0 and 1 arguments. 
The 0 argument (which seems to be proper way, regarding to the note given in the ActiveX section : Devicenumber (...)This differs from the equivalent .dll function which starts at 0 for numeration.) makes the console load for a few seconds, then returns a -2 value, which is a case not discussed in the documentation.

As a result, we currently have no clue on how we can fix this or even see a path to debug further.

Any idea will be welcome,

Thank you again,

Cédric

Cedric,

Please see the friend request I sent you.

I will check on these.  Those dates seem correct.

Thank you. Did the PROM infos or the weird returned values gave you any clue on what we could try next ? Since I ran out of ideas, I'd like to send the proper D4100_GUI_FPGA.bin file to the card, but I'm afraid that a wrong .bin file or incorrect procedure could brick the card. Could you please provide the correct file for our card and a snippet on how to properly send it (by using the .dll) ? Thank you.

Cedric,

Since you are using the board with the XCF16 PROM the file is different that the newer ones for the SPI PROMs.

I also do not want to send you the wrong file, but the BIN file would not brick it, since it is volatile anyway.  I will send you a couple of different ones to try.

Cedric,

Sorry for the further delay for the US holiday weekend.

Fizix

Cedric,

I am sorry that I dropped the ball on this.  Do you still need help with this inquiry?

Fizix

Hello Fizix,

No worries, I can understand.

However we are indeed still needing your help. You told us that you'd send us the correct program and we are still waiting for it.
Since we had to make a proof of concept, we ordered another TI DMD which cost around 2000$ (and are encountering errors with it), but we are expecting to have both cards eventually working. I feel really incofortable having to throw away a 10k$ equipment without being able to tell what's wrong with it.

Best regards,

Hello again Cedric,

I am sending you a friend invite because I would like to set up a call with you on this issue.  Do you know when the board was purchased?

Reviewing the numbers on the PROM this is a very early version of the EVM.  You will need version 1.x of the GUI.  

Fizix

Hello again Cedric,

I see we are already "friends".  Please check the private message to you.
