Problem with flash
Posted: Sun Sep 17, 2017 9:31 am
Hello.
I am using Sparkfun ESP32 Thing with Arduino IDE, yesterday I was doing some I2C communication experiments. Suddenly the chip stopped receiving new programs - upload always halts with:
The serial monitor shows:
There is no reaction to RST button but button 0 causes serial to show:
Running "esptool.py --chip esp32 --port COM17 erase_flash" does not fix the problem, result: "A fatal error occurred: Timed out waiting for packet content"
Running "esptool.py --chip esp32 --port COM17 flash_id" shows a problem with flash being unknown:
Is there a way how to fix this or is the board dead? According to scheme the flash should be Winbond W25Q32FVSS - 4MB SPI Flash.
Thank you.
