Hi All,
When ON the LDO (LDO_ARM, LDO_SOC, etc) in i.MX6DQ, the inrush current flows because the rising-up of LDO is precipitous.
So, we'd like to decrease the inrush current.
Could you tell me the way of loosen the steep LDO output in i.MX6DQ?
Best Regards,
Keita

Hi Keita
at power-up time (when processor is not fully powered yet) there is
no method to set the slope of LDO output inside i.MX6DQ.
After powering processor, PMU_MISC2n REGx_STEP_TIME bits define ldo timings,
that is when LDO changes one voltage to other, voltage changes with
steps defined in REGx_STEP_TIME .
During processor power - up (that is meaning of LDO "inrush current") - REGx_STEP_TIME
is not used.
Unfortunately there is
