15 years agoA little more information .....
I have gone back to a HPC with altmemphy setup that I have used many times from the megawizard... It seems that the local_init_done signal never goes high which tells me that the ddram is not getting calibrated, or initialized or something correctly at the beginning... The issue above then causes the VIP Frame buffer to fill it's fifo as the CTI puts in data and when the FB fifo gets full it drives the ready signal low and holds off the CTI... but the real issue is the ddr not getting brought up correctly.... Any thoughts on this? thanks, david
