Sorry sir, my error is Cannot connect to target. Error: 2
I have tried executing the code in different computers and esp-idf versions and I still get this error. I have also tried it with different ESP32 dev boards.
Thank you

Please give a bunch of context as well. When do you get the error, what are you trying to do, what are the log lines leading up to the error, what hardware are you using?

The only thing I hadn't tried was trying other cables. I have already found the problem.
Thank you very much for answering sir

Sorry sir for bothering you again, but I have a problem. I have uploaded to the binaries folder the binaries of a project that blinks a LED to check if the flashing works correctly. But after flashing the files and disconnecting the uart0, gpio0 and enable pins, and reseting the slave slave esp32. The LED does not blink.
What should I do to execute the flashed firmware in the slave ESP32?
Thank you
