Other Parts Discussed in Thread: DLPC3433
Hello, I have a custom board with the DLPA2000 and the DLPC3433. I made an initial test setting PROJ_ON high and it worked fine. I could see the splash image in the display. However, after some hours I reconnected my setup and no light came to the display. I debugged and found the fast park condition. Reset is going low around 40 uS after ParkZ goes from high to low. So nothing starts now. The setting has not change, and I would like to find out what is causing the park condition. The datasheet suggests some power failure, but so far all power rails are there and at good values. Any suggestion?
