I downloaded the D1 mini schematic and the part I was referring to is U2, a transistor-pair UMH3N. I don't know how the D1 mini is expected to boot-up when you use the USB. Are you running rshell?

You said you stopped using the CH340C, did you remove it from the board?

Yeah, this is all confusing. I'm just annoyed by, what seems like, the inconsistencies in the system. I disconnect everything and programs won't upload or run like they used to. I just don't get it. So discouraging. What should have taken me a week has taken three weeks because of all of this.

I was hoping that knowing if you were using rshell and how you "stopped using the CH310" might provide more clues.

Hmmm, I saw a message that said you had tried rshell, but it has disappeared.

I would focus on a standard un-modified board and rshell, at least to try and determine why rshell doesn't work.

I moved it to the Third Party Programs section, or whatever the name is. I have two new ESP-12F chips with a development board that I snap it into. I can't even do

Code: Select all

esptool.py --port COM3 chip_id
on it.
This is what I get:

Code: Select all

c:\Projects\ESPnow>esptool.py --port COM3 chip_id
esptool.py v3.0
Serial port COM3
Connecting........_____....._____....._____....._____....._____....._____....._____

A fatal error occurred: Failed to connect to Espressif device: Timed out waiting for packet header

Have you checked that you have a connection to COM3? How many different boards are you working on?

I would often get the same. Don't know what fixed it, but haven't seen it for months.
Can you erase the chip?

I'm using the port that showed up in Device Manager on Windows. This is a new board I've been working with while I try to figure out the other one we've been working on. Looks like the new one is even worse for me. Can't even flash it.

No, I cannot erase it. Same thing happens. Here is the new chip and board I'm using that's been giving me this error. It's an ESP-12F.

Downloaded a ESP-12F datasheet but it is not the same PCB layout as yours. Who made your board? Have you got a Linux machine?
