I would like to ask about i.MX28 power supply.
Could you show me what registers of i.MX286 are back-upped by battery.
Especially, my customer wants to know what registers among those are related to returning from backup state.
It is grateful if you can show that.
Could you show me what behavior will occur on i.MX28 when supplying 3.3V when register setting of Battery(A15) pin is 4.2V?
Is it possible for i.MX28 not to boot-up?
