ESP32 Forum

Hello good people of Espia

I am trying to make a standalone image which i could flash on another person computer (upload and remotely flash the connected device...), using windows 10, esp-idf v4.2, python 3.7, the program compiles and debug is working, also idf.py build is working correctly
Is using the esptool the way to go? also, in case a fix is not available at hand, is there another way to perform the operation?
Big thanks

esptool.exe --chip esp32 make_image wifi_station.elf
esptool.py v2.8

Any replies would be very much appreciated, is there another way to approach the matter in question? thank you
