ESP32 Speed up loading

[Adham Aboud]

Hello All,

Is there is a way to speed up the boot procedure with ESP32?

[mikemoy]

It's typically up and running in under <=1 second. Why are you needing it faster than that ?

Because batteries. Or because instant response (like a smart bulb remote).

Hello WiFive and thanks for your response.
I see that it's more than 1 second. I don't exactly know what is the booting time. I can measure it later

The need for faster boot is because of response to HW that needs to set a declared GPIO for high level before 1 second passes.

Because batteries. Or because instant response (like a smart bulb remote).

Well you may want to do that in custom bootloader then or wake stub if you are deepsleeping
