so i have a "TTGO Lora32-Oled V1" board. It was working fine yesterday and now I get this output, when I try to upload anything
I tried all the boot, rst pin options. But then looking at the serial monitor I don't see anything. So no "waiting for download" nothing.esptool.py v3.0-dev
Serial port /dev/ttyUSB0
Connecting........_____....._____....._____....._____....._____....._____....._____
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
I tried connecting GND to GPIO0, still nothing.
The serial connection is there though, since if I write
Code: Select all
ls /dev/tty*
I have another board here and this one flashes fine.
So I guess my board is broken or not? What I don't get is how it was working fine yesterday and now it doesn't anymore I didn't change my circuit.
Interestingly when I started my circuit today I didn't get any serial output from the esp32, so it must have broken at some point. I'm kind of worried I'm gonna break another one.
I either power it through my laptop or through a Teensy 3.6, the connections are:
ESP32<-> Teesny3.6
GND <-> GND
3.3V <-> Vin
GPIO23 <-> GPIO7
GPIO13 <-> GPIO8
I would really appreciate some help.
