GK,

What is the purpose of this design? I recommend following the DLPC300 reference design to prevent these signals from interacting in an unintended way:

GK,

What kinda of problem symptoms are you referring to? Do you need assistance with layout guidelines or are you debugging a hardware issue?

GK,

I don't recommend tying the DMD_PWR_EN line to the RESET signal.

Are you still encountering issues with your system design? If so, please provide additional details regarding your current debugging problem. Otherwise, I will tentatively close this thread.
