I have a ESP32 WROOM with USB-C connector which I'm having trouble programming. Every time I try to upload any sketch to the device I get the below error. I've tried changing various settings to see if it will upload to no avail. I have nothing connected to it. I had similar issues with the ESP32 WROOM 32D but I figured that out. I have more of them on the way but I'm concerned that they won't work either until I figure out the correct settings. The board is labelled as a ESP32-WROOM-32 with no letters after it. No U, D, S etc. I know some USB-C leads fail to charge iOS devices because of a missing resistor...... I'm wondering if this is the same issue. Any ideas?
I've tried pulling pins 2 and 12 to ground. That had no effect either.
Also, I have an extension board that came with it. It has micro and C type connectors on it. When connecting the board to my PC using either of the USB ports, my PC cannot find the port. If I connect the lead to the ESP32 direct, the port appears. Any ideas about that?
