DLPC3433: How to customize Flash file for a custom board

Part Number: DLPC3433
Other Parts Discussed in Thread: DLPDLCR3010EVM-G2, DLPA2005, , DLP4710, DLPC3478

Tool/software:

We have been using the DLPDLCR3010EVM-G2 and have been able to use DLP Light Crafter Display to change timing, change splash screen and create custom batch files. These all work just fine on the EVM.

We are ready to implement the design on a custom board. We generated the file FWSel_DLPC3433_DLPA2005_pm1_i2c0x36_v7p4p3.img using TI DLP Pico Firmware Selector to match the hardware configuration on our custom board. However when using this file as the Input Image on DLP LightCrafter Display (Flash Image Update) we get the error: "Flash Image Update Failed: Input flash image errors".

What is the process for modifying the firmware file for a custom board? We would like to update the splash screen and implement batch files.
