Hi,

I am using customized i.MX6 SL board with TPS65910 PMIC. I am able to wakeup the board from the STANDBY low power mode by using TPS65910 PMIC rtc but failed to wakeup the from the FREEZE low power mode.

OS - Linux

Procedure:

date -s "2016-07-20 11:03:59"

hwclock --systohc

echo +40 > /sys/class/rtc/rtc0/wakealarm

cat /proc/driver/rtc

Hi Vipul

"Freeze" low power mode is not supported in i.MX6 nxp

bsp releases, please refer to attached Linux Manual

Chapter 22 Low-level Power Management (PM) Driver

for supported modes. One can try them using nxp bsp on

linux-2.6-imx.git - Freescale i.MX Linux Tree

Best regards

igor
