DLPC3433: DLPA3000 + Optical Module Trouble Booting Up

Part Number: DLPC3433
Other Parts Discussed in Thread: DLPA3000


I am having trouble getting my custom board to boot. The board uses the DLPC3433 and DLPA3000, the scenario is as follows:

1.) I have the optical module (light engine) connected with a DMD connector and the optical module is connected with proper power supply connectors

2.) The host processor boots (linux) and I set the PROJ_ON to HIGH (3.3v) confirmed with a multimeter

The problem: The HOST_IRQ does not go low to indicate that the system is ready, no light is displayed through the optical module (light engine), and the DLPC3433 is not discover-able via I2C.

Any suggestions on where to start looking or what may be the cause of this problem?

Thank you,
