Burning efuses in the factory / during manufacturing of a product

[mikemoretti]

Hi,

We're in the process of setting up manufacturing for a product we're making that contains an ESP32 module. I found the awesome esp flash tool that lets us flash our factory image. However, there doesn't appear to be a similar tool to burn efuses. We need to burn the flash voltage efuse in order to flash our modules; and we're going to have to set up MAC addresses too. I'd rather not have to install the IDF on every manufacturing PC as it's rather large. Is there some tool for burning efuses like the flash tool? If not, why not?

Thanks,

Yeah, I saw that, but we had problems getting esptool to install/work with Windows python. It would be great if it was a proper app and not a python script that you need to load all sorts of dependencies for (python, libraries, etc).
