I’m writing to kindly check if there is any update on the RGB project files you mentioned in your previous reply. Our team is currently waiting for the necessary code, calibration, and configuration files for the puddle light application (similar to HUD but without PD feedback). Additionally, we would greatly appreciate your guidance on the two questions I raised earlier regarding calibration without PD connection and the procedure via ACP tool. Could you please let us know if there is any progress or if there is anything else we can provide to assist? Thank you very much for your support.

The micro-usb port on the controller detached. I am wondering if TI offers a service to reattach the micro-usb port or can recommend another solution without having to purchase an entire new board.DLPLCRC410EVMTest &amp; Measurementhttps://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1649337/dlpnirnanoevm-dlp-nirscan-nano-evm-no-power-led-and-gui-cannot-connect/6361938Thu, 28 May 2026 05:51:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:93523805-35c2-49cb-8918-6d71507ec0cc동현 성Thank you for the suggestion. Unfortunately, I should clarify the device state more precisely — the issue is more severe than just the GUI not connecting, and LM Flash Programmer also cannot detect the device for the same reason: Current symptoms (after the failed CCS debug attempt): The power LED does not turn on at all when the USB cable is plugged into the APP port. The device does not enumerate on USB. It does not appear in Windows Device Manager under either VID_0451&amp;PID_4200 (normal mode) or VID_1CBE&amp;PID_00FF (Stellaris DFU mode). Windows logs zero USB enumeration events when the cable is connected. Verified the issue is on the device side , not the PC: Tried multiple known-good USB cables (data + power capable). Tried multiple USB ports on the PC. Tried a completely different PC — same result (no LED, no enumeration). The PC&#39;s USB host controllers / root hubs all report OK, and other USB devices enumerate normally on the same ports. Why LM Flash Programmer cannot help in this state: LM Flash Programmer (USB DFU mode) requires the device to first enumerate as Stellaris Device Firmware Upgrade . Since the device is not enumerating on USB at all — and the LED is completely off, meaning the MCU is not even powering up — LM Flash Programmer&#39;s device list stays empty and there is nothing to flash to. Even a blank or corrupt firmware would normally fall back to the TM4C129 ROM USB DFU bootloader and enumerate on USB. The complete absence of enumeration suggests the MCU is not running at all. My question: This appears to be a hardware-level power issue rather than a firmware problem, since: The LED is hardware-driven by VBUS, independent of any firmware or driver. No USB enumeration occurs even at the lowest level. The problem reproduces on a different PC. There was no physical damage or mishandling — this happened immediately after a failed CCS JTAG debug attempt (note: I do not have the DEBUG-port ICDI cable; only the APP USB was connected during the attempt). Is there a hardware recovery procedure for this state — for example, a force-DFU button combination, a boot mode jumper, or any way to manually reset the power circuit? Or does this indicate the EVM needs to be repaired/replaced? Additional symptom: When the USB cable is connected, even though the power LED stays off, I can hear a faint high-pitched sound coming from the device itself — it sounds like a coil/switching noise. This suggests that USB VBUS power IS reaching the board, but the on-board switching regulator appears to be entering a protection/hiccup mode (the regulator is repeatedly trying to start but failing — typically caused by an over-current condition or a short on one of the internal rails). The MCU itself never boots up, which is why there is no LED, no USB enumeration, and no DFU mode fallback. In addition if I have to repair the device, it will be very grateful if you could suggest any place I could ask for this information in South Korea. Sorry for the long response.

Thank you for additional information, this should be entirely a software issue. You will need to put this into a boot loader mode by pressing and holding the scan button on the EVM while powering up the unit. Please advise if the GUI still cannot be used - you will need to reload the EVM with a different version of the Tiva firmware. You should also be able to utilize this LMFlashProgrammer tool outside of the GUI - this will be necessary.

Instead, it represents the available mirror exposure associated with the selected reset mode configuration (Global, Single, Dual, or Quad). The reset mode determines how the DMD mirrors are updated and grouped during operation, which impacts both the achievable pixel data rate and the effective exposure timing. For example, Global reset updates the entire array simultaneously which provides a longer exposure window but reduces the overall pixel throughput, while Single reset prioritizes maximum throughput and minimizes exposure dead time. Dual and Quad reset modes operate between these two extremes and provide a balance between throughput and exposure timing characteristics. The actual image-to-image transition timing depends on additional system-level factors beyond the exposure period itself, including the pattern loading timing, controller sequencing, DMD mirror settling/reset behavior, trigger synchronization, and the selected bit depth and pattern configuration. T he values shown in Figure 8-3 are primarily tied to the reset architecture and DDC_CLK operating conditions (480 MHz in this figure) and are not fixed “transition times” that remain constant regardless of trigger rate. In practice, the achievable exposure timing and pattern behavior will depend on the operating frequency (for example 10 kHz vs 15 kHz), selected pattern sequence, and overall system timing.

These values represent the approximate internal package routing/trace lengths associated with the high-speed signal paths inside the device/package . These numbers are primarily provided as a reference to help with high-speed PCB routing and signal matching across the differential data lanes and are not intended to be used directly as propagation delay values for timing calculations. For PCB routing and timing matching, Section 9: Layout of the DLP991UUV datasheet shows the routing constraints in Table 9-7 under the “High-Speed Serial DMD Interface Routing Constraints” and are the specifications that should be followed. The high-speed data lanes should be matched relative to their associated DCLK differential pair within &#177;45 ps, and the differential intra-pair matching should remain within &#177;2 ps. These are the primary timing constraints intended for PCB routing and signal integrity optimization. TI does not provide separate internal pin delay timing values for individual DLP991UUV pins beyond the information included in the datasheet/package documentation.

Yes I have been using this device for the past 2 months without any problems. I plugged the power into the right port and have been using the correct power source. This happened suddenly yesterday afternoon while I was changing some codes using CCS (Code composer studio) and tried debuging. After failing the debuging process, the device seems to not connect to anything, including the PC (according to the DLP NIRscan Nano GUI) so I can&#39;t even update the Tiva Firmware to the original state. I am wondering if this is a software problem or hardware problem (there was no physical damage to the device)https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1643694/dlp4620sq1evm-inquiry-regarding-display-size-and-focus-adjustment-range-for-dlp4620spguq1evm/6359754Wed, 27 May 2026 00:35:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:5aeb2684-ec42-4490-820e-be51a3293c8bArita YoshikiHi John, Thank you very much for obtaining and sharing the refocused MTF plot so quickly! This new plot is much easier to read and shows a very reasonable and natural performance fall-off from the center to the edges. It completely clarifies our previous questions, and we now feel very confident about the image quality at the 70mm focus distance. Just to be absolutely sure as we review the data, could you clarify one point regarding the definition of the &quot;70mm field&quot;? Does the &quot;70mm field&quot; in the plot imply a 140mm diameter (i.e., a field height/radius of 70mm)? As mentioned before, the effective area we require for our evaluation is a 70mm diameter (Φ70mm) . If this plot actually covers a 140mm diameter area, it means we have more than enough performance margin for our target size, which is excellent news. Also, I completely understand the lens adjustment mechanism you explained (scraping off the epoxy to slide and pull the lens back by 0.6mm). We are very much looking forward to the evaluation results from your side next week. If possible, it would be highly appreciated if you could share a few photos of the adjustment setup or the modified lens appearance. It will be very helpful for our mechanical and optical teams. Thank you again for your great support, and have a wonderful weekend! Best regards, Yoshiki
