[Solved] ESP32 chip time splitting work into two cores and power saving

Hi,

I am working on a photobucket on an ESP32. A few puzzles have arisen.

First:
How do I boot the ESP32 as quickly as possible? Right now it takes 1.2s from reset or exit from sedation. Is it possible to go faster? How do you do this?

Drugo:
I managed to split the tasks into two cores. I want one to work all the time and the other temporarily. How do I sedate just one core to keep the other working? Do they have separate clocks and power supply? At the moment, they both shut down

Third:
I am interested in the power management and shutdown capabilities of individual components

Please help
Robert

Are you using Arduino Core? If so, it will be difficult. If you are programming directly from ESP-IDF, then: Link .

Putting only one to sleep is not an option. You can stop/enable a specific core with the functions esp_cpu_stall () and esp_cpu_unstall (). Link .
I know from practice that these are quite risky operations if you are not in control of the WTD.

In addition to sleep, the frequency can still be configured: Link

And how about the other so-called "system" tasks?

Thank you very much for your reply. It was useful

I used the Espressif IDE environment
