HI,

We want to auto power on the i.MX6ul board without any user interaction. Is  it possible to implement this mechanism on imx6 evk

hi Artur Petukhov.

case 1) boot -> onoff button use power off (SNVS_LP Control Register is TOP bit 1 set) -> no automatic power on.

case 2) boot -> "poweroff" linux command use power off (SNVS_LP Control Register is TOP bit 1 set) -> no automatic power on.

case 2) boot -> power adapter remove.  power off (SNVS_LP Control Register is TOP bit 1 not set) -> automatic power on.

how I can fix this? I do not need automatic power on. only on off button.

refencence manual please.

I hope it helps. Regards,

Thanks!

Do you have a pullup on the PMIC PWRON pin? If not, pull it up to the VDD_SNVS_IN voltage by a 10kOhm resistor.

Have a great day,
Artur
