Hi Nico,

First of all I have some questions to clarify.

nico weis said:

Yes but in Sleep Mode the Device do not Charge my Battery but that is that what i want

AM335x device has several low power modes: Standby, Deepsleep1, Deepsleep0, RTC-Only. When you say "sleep mode", do you reference to some of the AM335x low power modes?

"do not charge my battery" - do you mean that you want AM335x device (in low power mode) to charge the TPS65217 PMIC battery?

SO i HAVE to Modify my Driver

Which exactly is your driver? Do you mean TPS65217 PMIC driver?

Hey,

First of all i want to explain the Requirements:
1) The device must be turn on and off with the Power on button BUT the Power from the RTC must be always on
2) The device must be load over the Wall or the USB Adapter if the device is on Or off !
3) All the Powersupply Vbatt,Vusb;Vwall must be turned off from an Power Switch !

How can i do that ???

In BeagleBoneBlack board we have power button (S3 KMR231GLFS), I can not find "power on button". Do you mean power button actually?

In BeagleBoneBlack SRM we have the below info:

6.1.5 Power Button
In power off mode, the RTC rail is still active, keeping the RTC powered and running off the main power input. If you remove that power, then the RTC will not be powered. You also have the option of using the battery holes on the board to connect a battery if desired as discussed in the next section.

Per mine understanding this mean that when you press power button, RTC stays ON. It can go OFF if you remove the power jack cable.

Could you please clarify how you define that RTC is OFF when you press power button?

Also I want to note that this is Sitara AM335x device forum, and I can help you with questions related to AM335x device and its software (PSDK Arago linux).

Pavel
