Re: [SOLVED]Cannot erase flash, ESP32
What's the difference between the two (virtualenv and conda), and do you have a link to a decent guide for someone who has no experience with them?

Re: Cannot erase flash, ESP32
ah ok, ill try that.
what i meant by the "not the .py" version of the esptool, is that i installed it from the standard ubuntu repos, not using pip. it was there and installed it by running `sudo apt install esptool`.

Re: Cannot erase flash, ESP32
Hey sorry everyone. Something came up last night. Just woke up.
But yeah. Do you think that it could possibly be that I'm not using the .py version of the tool? I'm just using the one that I got from the repos in Ubuntu, by running sudo apt install espool.
