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

Not on the current version of the i.MX6UL EVK board.

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
