Other Parts Discussed in Thread: DLPC3470, DLP2010, DLPA3000
Dear Mayank Khandelwal
As you know, we have made our own board using DLPC3470 and DLPA 3000 to control DLP2010.
I have wrote the dlpc3470_dlp2010_dlpa3000_7.3.1.img which you sent to serial flash
However, it doesn't boot up.
The HOST_IRQ signal remains in "low" only for a very short time.
I know that If there is any fault occurs in DLPA3000 then it will make INTZ low and HOST_IRQ high
And then respectively it will make all DMD voltages disable.
So, my issue seems to be related to the fault condition.
Is there any tool to find out what is causing the fault?
For the detail, I can send you below files
(1) a couple scope shots (INTZ, RESETZ, VRST and HOST_IRQ)
(3) PCB file
I would appreciate it if you could send me some information about our issue
thanks and regards.
