DLPC3470: Failed to load FW data from flash during initialization

Part Number: DLPC3470
Other Parts Discussed in Thread: DLPA2005, , DLP2010LC

Hello,

I was currently conducting a development test using DLPA2005 + DLPC3470 + DLP2010LC.

that was design for the Powerup sequence provided by DLPC3470 datasheet, but DLPC3470 Chip cannot read the firmware in the serial flash.

And when PROJ_ON is applied by Toggle, SPI_DATA can be checked.

I will send you the data I measured, and I would appreciate it if you could tell me if there is anything that needs additional confirmation.
