I have a legacy design that includes an iMX27 and LPDDR. I am trying to take some measurements of the system power with various components powered off (or close to it) to calculate board overhead.
I would like to disable the SDRAM, but I don't know if just not configuring it is enough to set it in the lowest power mode. I am running application code from internal SRAM so I don't need the SDRAM at all. How do I power it off (or close to off) from the iMX27? Is there a mode I can put the SDRAM in that is essentially off?
