Adding Power-on button on Tep0700-imx6ul

[caglarabidin]

Hi all,

I am using yocto 2.1 krogoth on Tep-0700 imx6ul Technexion panel board. The board does not have power-on button.  I am looking for a way to  assign  one of the gpio pins of the board as a power-on button. How can i make  such a modification  ? I have searched snvs option but  i am not sure whether snvs power-key  can be routed to gpio  or not. Any information would be helpful.

Thanks in advance.

Hi caglar

this board uses pf3000 pmic and you will have to add some circuitry for

power-on feature, some example can be found on spf-27392 (p.19) Sabre SD schematic.
