In your initial post you were talking about the Starter Kit. It has TPS65910A, not TPS65217B. Which one are you interested in?

The Beaglebone Black is built with TPS65217C. Please refer to the document http://www.ti.com/lit/ds/symlink/tps65217c.pdf. This PMIC can be powered down when the power button is pressed for longer than 8 seconds.

Hello Sir,

Thanks for your reply. I have studied about the documents, can you help me shutting down the pmic by means of software. One more question sir, could you explain me where we need to change the password protected register values in kernel and also mention path of it.

Thanks in advance.

I am sorry, I can't help with software. I support only hardware issues on the forum.
