Hello Francesco, We are working on suspend-to-ram support for j7200 and j784s4. During suspend-to-ram the SoC is fully powered-off (thanks to the PMIC which powers off all the power rails except the DDR which is in self-refresh), like on j7200. Please let me know if you want more details. Regards, Thomas
