HI,
The customer asked if the TMDSEVM572X can boot without pressing the power switch.
As a result, when J5 is shorted, EVM starts without power switch.
Is this correct?
I thought J5 was just a feature to avoid automatic PMIC shutdown.

Hi Kouji,
The behavior of the powerhold signal will depend on the boot pins. For the TMDSEVM572X, connecting the J5 jumper will short the power hold to LDO_VRTC. That voltage will be present as soon as the external power supply is connected and, since it is connected to powerhold, will turn on the PMIC. Based on this I don't believe that the button will need to be pressed. More detail can be found in the following post.
Regards, Bill
