3.1.3 Programming the DLPC4420AEVM and Displaying a SPLASH Image

Follow these steps to download and configure the DLPC44xx GUI:

  1. The Projector Control (.projector) and Firmware binary(.img) files are located in the install directory. The same procedure applies to the DLP470TEEVM and DLP780TEEVM with the appropriate firmware.
  2. Setting up Communication Preferences:
    1. DLPC44xx GUI supports USB and I2C communication. To change these settings, please go to Edit- >Preferences->Communication.

    2. For USB, please select the USB interface.
      Note: USB is the preferred method to download the firmware flash image to the projector as USB is much faster than I2C.

    3. An error message can appear saying the USB driver cannot be opened. This is expected, as TI has not yet enabled communication on the board. Click OK on this error.

  3. Projector Control Configuration:
    1. Run the DLPC44xx GUI tool and select the Projector Control sub-tool.

    3. Make sure the desired Projector Control file is checked, then select OK.
      Note: If the user wants to use one Projector Control file at a time, then deselect the files to hide before selecting OK.

  4. Flash Loader Configuration:
    1. Select the Flash Loader sub-tool, and then select the Browse button. After navigating to the installation directory, navigate to the DLPC4420_Software_Files folder and select the “Flash_DLPC4420_DLP660TE_p66_TRP_4KUHD_S610_LED.img” file and click on open.

    2. Select Complete Image Download for first time download. By default, the flash has the boot loader pre-loaded; uncheck the Skip Boot Loader Area.
      Note: Check Skip Boot Loader Area only if the bootloader needs to be upgraded.

    3. Connect DLPC4420AEVM to PC via USB. Make sure USB communication capability by clicking Reset Bus on the bootloader menu in the DLPC44xx GUI. The Status field appears as follows:
      GUID-9779AD8A-C5BD-4ABB-9006-B6D3EC2243A6-low.png Figure 3-11 Communication Between GUI and EVMs
      Note: If there is an issue with USB communication, then turn off DLPC4420AEVM and disconnect then reconnect USB cable and power on board.
    4. Select Start Download to begin. The loading process takes between 5 and 10 minutes.
    5. After the download has completed, switch SW1 to off and switch the power to the unit under test (UUT) off. Remove the jumper on J31 from the DLPC4420AEVM board.
    6. After removing the jumper, re-enable power to the DLPC4420AEVM. Switch SW1 to the On position. A Red LED appears after a few seconds. The Red LED shuts off and a green LED begins blinking. After the blinking LED appears, the DLP Texas Instruments logo is visible on the DMD for a few seconds and appear as or similar to what is seen in Figure 4-12.

Turn the switch back to the off position before connecting the USB cable to DLPC4420AEVM. The power supply does not have to be disconnected before connecting the USB cable. Once the USB cable is connected to the DLPC4420AEVM (and the PC), turn the switch on the DLPC4420AEVM to the on position.
