DLPU102C December 2020 – July 2024
A batch file can be added to the firmware to be used as the default batch file to be executed during the power-up sequence of the DLPC900. Or a batch file can be added to be executed at any time after the power-up sequence has completed to perform some action. Some special considerations must be taken if adding pattern images and a batch file to the firmware image. See the note at end of Section 4.9.1.2 for a description of these considerations. Follow these steps to add the example batch file from the previous section to the firmware.
The user must exercise caution when selecting the correct firmware file. Install DLP LightCrafter GUI version 5.x or later and FW version 6.x or later. Operating or updating the firmware on the DLP LightCrafter DLPC900 GUI version 4.x (or earlier) renders the EVM inoperable.
When updating firmware for the DLP LightCrafter Dual DLPC900 EVM, the GUI creates two firmware files. One for the primary controller and one for the secondary controller. When selecting a firmware file or an updated version, select both of the files named [firmwareimg]-primary.img and [firmwareimg]-secondary.img by clicking each while holding the Ctrl key.
If the batch file is to be a default batch file to be executed during the power-up sequence, then continue to step 12, otherwise go to step 13.
When updating firmware for the DLP LightCrafter Dual DLPC900 EVM, the GUI creates two firmware files. One for the primary controller and one for the secondary controller. When selecting a firmware file or an updated version, select both of the files named (firmwareimg)-primary.img and (firmwareimg)-secondary.img by clicking each while holding the Ctrl key.
The name of the firmware file created by the GUI includes a timestamp, verifying that new firmware does not overwrite any previously created firmware files.
