Re: Hardware Pin Assignment
Are you using the Wrover or the Wroom ?

Re: Flashing ESP-Wroom-32 in production
Glad you have it figured out, but I wanted to clarify this for others that may see this post.I was referring til JTag, which by "google" it seems to be possible, but not recommended.
There is nothing wrong at all programming it with JTAG.

ESP32 Pocket Programmer ?

Re: Flashing ESP-Wroom-32 in production
