8MPLUSLPD4-EVK - Autopower ON

ramkrish — Tue, 07 Jul 2026 13:24:06 GMT

Hi Team,

8MPLUSLPD4-EVK turns ON (boots) when power supply is provided and SW3 is turned ON.
Based on our understanding and assumption ONOFF button (SW1) needs to be pressed to turn ON Board.

But in actual case EVK turns ON without pressing ONOFF Button *SW1.

Could you clarify how this auto power on works and use case of ONOFF button?
Correct me if my understanding is wrong

Hello @ramkrish

I hope you are doing very well.

Actually, that behavior is correct.

When you Turn On the SW3, is expected that board will power up.

When you power off the board by software, you can Turn on again with the SW1 (ONOFF).

Best regards,

Salas.
