- Baud Rate: 115200
Starting connections:
- TX-RX
- Rx-TX
- Io0-Gnd
- Io15-Gnd
- Gnd-Gnd
- RST-3.3v
- En-3,3v
- 3.3v-Vcc
Upload
Get the following error messages:

the selected serial port _ does not exist or your board is not connected
Changed Connections:
First: Io0 from Gnd to Open
Then: RST from Vcc to Gnd
(Same error messages)
Tried about 6 different combinations of the above two
(Same error messages)
I reread your messages from earlier help session – you tell me to restart the ESP. I don’t know what that means. Only thing available to me is the Upload button. I don’t think that’s what you mean.

Did you select the COM port? Can you double check? It looks like the COM Port might not be selected…
Otherwise it simply means that your ESP is not in flashing mode. I know how frustrating this is, but sometimes it also happens to me and I have to try the setup 3 to 5 times before it works.
The ESP needs to be reset while GPIO 0 is connected to GND. Make sure the COM Port is selected.
