What causes this? And how can I set the ESP32 back to the way it was so that it doesn’t require me to hold the button down when flashing it.
Some have a UF2 bootloader mode; which Thing Plus are you using?
Thing Plus U.FL.
When I flash it from my linux desktop it doesn’t require the boot button to be held down. I have since researched and learned that it’s a USB driver issue.
How did you solve this?
I never really did. The issue still exists if I flash the unit from Windows 10. Doesn’t happen when I flash from Linux mint. No clue really, supposedly this is a common USB driver issue.
Is a Mac you’re using when you have trouble?
If so, you need updated drivers.
