Is your stub based on https://github.com/espressif/esptool-legacy-flasher-stub/ ?


Frankly, Yesterday was the first day that I was aware of this forum. I do know that septool has got the stubs with the functionality that I want, but ChatGPT directed me to a dead link on Github. I think maybe ...

Sounds like an XY problem. What are you actually trying to achieve, what's the bigger picture here?


There are 2 main microcontrollers that I use frequently. This is Atmel (now MicroChip) and ESP32.
My projects are some times with sale in mind, and that involves flashing a new microcontroller ...

Perhaps this will help you?

Ooo!
This looks like a gold mine.
I will definitely learn a lot from this.
Thank you so much!

Kind regards,

That said, pull-down resistors should not hurt.
In my case, I used another ESP32 to control the transistors that controlled "EN" and "BOOT" on a target ESP32.
In my project, I ...
