ESP32 Forum

Hello,

I want to compare the voltage used by ESP32 when the tasks are pinned to single core or to both cores.
In comparison, I want to switch off/deep sleep just a single core.
Is there any way to do the same. Thanks.

You can enable single core mode ("run freertos on first core only" option) in menuconfig. With this option enabled, APP CPU will be clock gated. This will give you a few mA of current savings.
It is not possible to power down APP CPU separately from PRO CPU.
