There are 2 more resets one for DDR controller and one for DDR PHY controller. Those 2 controllers have no drivers in Linux at the moment (and probably will never have). These 2 extra resets are controlled in the RAM initialization phase by bootloaders. Thank you, Claudiu Beznea > > regards > Philipp
