Waking up time tames about seconds!

Helo guys

I am working with few types of ESP32 , S2 mini, C3 zero , C3 super mini and some more. Each one is mounted with the latest Micropython frimware (up to date for 7/7/25)

For my project i need my device to be in deepsleep mode and wake up in a resneble time of less than a second. the rest of the post in the metter do not refer to Micro python unfortuntly.

my mesurements so far shows it take aroun 2.87 sec befroe my first line of code is executed. (i can add the cool code i wrote if it helps anyones project)

After looking onlnr for ideas to improve boot time but nothing shows promessing idea to imrove dramaticaly the frimware upload time. there was idea to add my code to the frimmwear, delete some parts inside and recompile. it sounds super hard and with low chance to achive the 10-100ms boot time people mention in Arduino.

Chat gpt found online other people achive 100-500 ms upload time in mycro python. but i can not replicate this. perhaps it was a spesifice chip\ old frimware.

Does somone have idea how can this be imroved? Is it an inherent micropython issue and i must give up and change the entire project languge?

would love some help, thank you

The issue you see may be caused by your lengthy pure python code located in the file system.

I would suggest you to read the following note in github.
