Is my ESP32 dead?


Sorry if it is the wrong place, i’m newie on all this thing of esp, platformio, blogs and stuff.
I have got an ESP32 devikit. I started working on my app one week ago, with no issue until yesterday. Yesterday I started seeing some strange behaviour during the wifi connection, and today I cannot even connect to the ESP. What I see is this:

ets Jun 8 2016 00:22:57

ets Jun 8 2016 00:22:57

configsip: 0, SPIWP:0x00
mode:DIO, clock div:1
entry 0x40080034

The stars at the end grows with time. Some extra information:

  • Platform = espressif32
  • Board=esp32dev
  • Framework=arduino
  • Windows 10
  • Platformio+Atom = Ide 2.0.0-beta.4 - Core 3.4.0b9
  • Driver installed on windows 10 as "Silicon Labs CP210x USB to UART Bridge (COM4)
  • The serial monitor speed is at 115200 bauds.

Is my esp32 devkit dead? How can I bring it to life again?

Thanks in advance

Hi @koke.montoya!
Looks strange, the first step I would recommend is to completely erase your flash memory:

python c:\Users\YOUR_USERNAME\.platformio\packages\tool-esptoolpy\ --chip esp32 --port COM4 --baud 115200 --before default_reset --after hard_reset erase_flash

And then program the board with your sketch.
