DLPC3479: HOST_IRQ doesn't go to low.

Part Number: DLPC3479
Other Parts Discussed in Thread: DLP4710, , DLPA3005, DLP4710EVM-LC

Hello TI Experts,

We have made our own PCB with DLPC3479 and DLPA3005 to control DLP4710, however, it doesn't boot up.

- We have modified schematics from EVM, and  using different MCU.

- We confirmed that after settig PROJ_ON signal high, RESET_Z becomes high, but HOST_IRQ doesn't go low.

- We have written master and slave flash with "DLP4710EVM-LC_Firmware_v1.1.0.img" downloaded from TI site, meaning, same image to both frash.

-Also checked DLPA3005 out puts after PROJ_ON is high.

PWR1: +1.1V   >>OK

PWR2: +1.8V   >>OK

DMD_VBIAS: 0V   >>NG

Question:

 We have wrote whole image of "DLP4710EVM-LC_Firmware_V1.1.0.img" to Serial flash with starting address of 0x000000.

Is this correct?

Please give us any advise to solve the problem, thanks.
