Hello,
I'm using i.MXRT 1060 EVK board.
I'm testing a low power mode, especially SNVS and SUSPEND mode.
I used 'evkmimxrt1060_power_mode_switch_bm' example code.
In SNVS mode, PMIC_ON_REQ level is low and DCDC_3V output is 0V.
In SUSPEND mode, PMIC_ON_REQ level is high and DCDC_3V output is 3.3.V.
I don't know why PMIC_ON_REQ is high in SUSPEND mode.
I've tested it again after changing PMIC_ON_REQ to GPIO.
And I inserted code, PMIC_ON_REQ = 0, before __WFI() function was executed.
But I think system was locked, and a button wakeup was not working.
And a power consumption is higher than original SUSPEND mode.
I'm going to use SUSPEND mode to reduce power consumption, not SNVS.
In SUSPEND mode, I want to know how I set to low in PMIC_ON_REQ pin.
Thank you!
Hello,
>> In SUSPEND mode, I want to know how I set to low in PMIC_ON_REQ pin.
Unfortunately,Since SNVS_PMIC_STBY_REQ_GPIO5_IO02 will output a high-level signal under Stop Mode(Suspend Mode) for the EVK board. Sorry for the inconvenience may cause.
Have a nice day.
