Your system should work if you have designed the system following the expected DLPC964 controller reference design.

We only officially support the firmware files that are included in our releases - unfortunately this is taking time to make it to the ti.com website! Until then I will reach out to you and it should have Xilinx as well as Altera (5AGXBA5....) firmware.

As I&#39;ve mentioned before Message Previously, when developing the controller board for dlp9500 mirror, we only purchased Flash Memory (for DLPC410 ) from TI and FPGA purchased from Xilinx to complete it. Is my method different from what you said? I understand that the method I mentioned is general. Does encryption separately on FPGA only apply to DLPC964? Regards Richard Parkhttps://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1640904/dlpc964-i-fused-dplc964-fw-xc7vx415t-2ffg1158c-of-the-board-we-are-developing-but-there-is-no-done-signal/6335388Wed, 06 May 2026 21:02:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:112b6841-9106-46fe-b4cc-ce5922fc6edaMichael LyHi Richard, What I am trying to say is that Xilinx has encrypted an XC7VX415T-2FFG1158C FPGA. These chips come from the same wafer as a regular XC7VX415T-2FFG1158C, but they may get fuses blown before being sold or sent to TI. We are not saying the flash is encrypted. The FPGA has a key, and our firmware has the matching another key. These two keys must work together. Any compatible flash part for can be used for this FPGA so long as it is within the table from Xilinx&#39;s configuration memory compatibility page . It would be more correct to say we have an encrypted flash image (such as a .bin, .mcs, .hex, etc) for the FPGA config flash that is used to configure the encrypted FPGA. In short, we need encrypted FPGA (DLPC964) + encrypted build file (TI DLPC964 FW). Does this make more sense now? Regards, Michael Lyhttps://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1640904/dlpc964-i-fused-dplc964-fw-xc7vx415t-2ffg1158c-of-the-board-we-are-developing-but-there-is-no-done-signal/6335375Wed, 06 May 2026 20:52:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:022d2e89-129b-4e43-b931-42477059ddafrichard parkHello Michael I know that he FPGA is encrypted, which means the flash needs a special key that is contained within TI&#39;s firmware that gets loaded into flash. We also encrypt the FPGA we developed and use it. We also encode and use the FPGA we developed. Previously, when developing the controller board for dlp9500 mirror, we only purchased Flash Memory (for DLPC410 ) from TI and FPGA purchased from Xilinx to complete it. So I don&#39;t understand because they said I have to buy FPGA (DLPC964ZUM) this time. Am I right ? DO you have the encrypted Flash Memory (for DLPC964 ) ? Regards Richard Parkhttps://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1640904/dlpc964-i-fused-dplc964-fw-xc7vx415t-2ffg1158c-of-the-board-we-are-developing-but-there-is-no-done-signal/6335338Wed, 06 May 2026 20:22:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:05f2624d-920d-4901-b010-442f7684e589Michael LyHi Richard, Please buy the one listed in your picture. The reason this is so inexpensive compared to the one you bought is likely because TI has bought in volume and made a contract with AMD-Xilinx to continue buying units over time to support the lifetime of this product. If your board schematic and layout are done well, the TI firmware should work on your system. The package type is still FCBGA. 1156 is more than likely number of pins on the FPGA, which is what I have noticed when it comes to Xilinx&#39;s packages. The FPGA is encrypted, which means the flash needs a special key that is contained within TI&#39;s firmware that gets loaded into flash. The FPGA then boots from the image stored in flash. Aaron Black , please correct me if I am wrong. I may need to talk with Mike about this.

As I&#39;ve mentioned before, I have to develop with our designed board. and then As You&#39;ve mentioned before, I will purchase the DLPC964 controller purchased from TI. but I have some question. 1) is it ok ? the DLPC964 controller is DLPC964ZUM.(refer to bellow) ---&gt; Please answer 2) Because is the price of DLPC964ZUM (I know it as kind of xilinx V7) correct $733? The xilinx V7 FPGA (XC7VX415T-2FFG1158C) we purchased is over $5000 from Xilinx --&gt; Please answer 3) Is the package type of the DLPC964 controller 1156? --&gt; Please answer 4) If we purchase the DLPC964ZUM (the DLPC964 controller ) and replace XC7VX415T-2FFG1158C FPGA and then download DLPC964-FW . Can we used our board like this ? --&gt; please answer. 5) As I&#39;ve mentioned before, I know that the encryption is for Flash memory. the FPGA is not applicable.. Am I right ? --&gt; Please answer I will wait for your reply Regards Richard Parkhttps://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1639122/dlplcrc900evm-gui-issue/6335231Wed, 06 May 2026 18:40:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4290dc44-5142-460e-98ed-575b25c0bf5bAaron BlackHello! I apologize, I might have mixed up the DLPC900REF-SW and the DLPC900PROM. The latest GUI (DLPC900REF-SW) version is 5.3.0 but the firmware (DLPC900PROM) version is 6.3.0 and that is here - https://dr-download.ti.com/secure/software-development/firmware/MD-PxxKFHetoA/6.3/DLPR900PROM-6.3.0-windows-installer.exe.

That being said, the NNO_CMD_FILE_GET_READSIZE needs both the NNO_FILE_REF_CAL_COEFF and NNO_FILE_REF_CAL_MATRIX - these directly tie to the dlpspec_scan_interpReference() constant variables pRefCal and pMatrix. Additionally, you can refer to section 5.2.1 step 3 for the NNO_CMD_FILE_GET_READSIZE and NNO_CMD_FILE_GET_DATA subsequent commands to transfer the data for each of NNO_FILE_REF_CAL_COEFF and later NNO_FILE_REF_CAL_MATRIX - the example uses NNO_FILE_SCAN_DATA as the parameter, but the flow is the same.

This is why only the DLPC964ZUM can accept the firmware that TI provides, which is encrypted with our LightControl ™ firmware. To help answer on Aaron&#39;s behalf, If you were to replace the FPGA, we strongly recommend you go to a third party that specializes in removal and cleaning of these high-density BGA chips. Assuming your design is has dual-sided placement, we would not want to run the risk of delaminating pads on removal or applying incorrect heat leading to thermal shock or components&#39; solder pads reflowing on the opposing side by accident. The same applies for installation--with a high-density BGA, it is best to have an automated tool do it or have an expert handle it with proper verification tool (such as X-ray) to check that no pins are shorted together and have proper electrical connection. With that said, if you were to flash the DLPC964ZUM after installing, functionality would depend on your design and layout. I am not sure if there is another solution, but I will defer this to Aaron and Tristan in case they know.

We are displaying a white image on the DMD with no filter wheel and are seeing a flicker that happens 6 times every 60 Hz. We have measured just the light source and this signal is not present. I am attaching a plot below. We are using a photodiode to measure this so fractional current is just the relative photocurrent/intensity. I have tried changing settings on both the diplay settings on my computer and on the evaluation board USB GUI. The light source is external and not being controlled by the evaluation board. Is this 60 Hz signal expected and is there anything we can do to fix it? This signal is the last obstacle from fully testing the DMD in our instrument prototype.DLP800REEVMDLPC4430EVMTest &amp; Measurementhttps://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1642318/dlplcrc900devm-plm-not-connecting-to-lightcrafter-gui----controller-dmd-not-compatible-error/6334800Wed, 06 May 2026 14:33:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:a41ed28d-d5a2-4d10-b9d4-88bce364b676Assia BenachirDear Aaron, Thank you for your reply!

The calibration data will contain HW parameters required to drive the RGB LEDs so as to meet the brightness and white color point required. Because these HW settings (LED on time, current levels, etc.) are heavily dependent on the particular LEDs and optical engine efficiency, this calibration data can be stored in the EEPROM on the DMD PCB board. Pairing of different controller would not affect the calibration results. You can find more information on the RGB LED calibration for HUD systems here Thank you, Regards, Aishwaryahttps://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1639122/dlplcrc900evm-gui-issue/6334139Wed, 06 May 2026 06:15:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:c402f433-b7f1-4a90-a60a-07685abdac72TI-CSCHello Aaron, I have installed both DLPR900PROM and DLPC900REF-SW(this link gives me v5.3.0) from the website links you gave me.
