Re: Can not put code to board using ampy

Purtting the script to the baord ios the first step.

Re: ESP32 can't run the program after reset or re-supply power

If you do not store the code in a file on the device, it is lost after reset. There are many tools to copy files between your PC and the Micropython device, like rhshell, ampy, webrepl, upycraft, ...
