i.MX7 with 400MHz DDR3L hangs when exiting self-refresh - NXP …

WebThe self-refresh entry command SRE and the self-refresh exit command SRX are supplied to the refresh control circuit 200. When the self-refresh entry command SRE is issued, the semiconductor device 100 enters a self-refresh mode, and performs a self-active refresh operation based on a refresh address generated in the semiconductor device 100. WebThe PMU self-refresh signals must be connected to the PrimeCell MPMC MPMCSREFREQ and MPMCSREFACK signals. When MPMCSREFREQ is asserted, the controller closes any open memory banks, and then puts the memory into self-refresh mode. The MPMCSREFACK signal is used to indicate to the PMU that the external memories are in self-refresh state. … mark rosner carload express
