A fatal error occurred: Timed out waiting for packet content - problem after writing to SPIFFS memory of ESP32

Postby electromania » Wed Jan 17, 2018 1:51 pm

I noticed there are several threads related to this problem, but i am creating new because this is the problem i am encountering after writing to SPIFFS memory of ESP32. I have raised issue on github here https://github.com/espressif/esptool/issues/263

After writing to SPIFFS memory for long time (overnight), the problem of . I had perfectly working wemos board. i kept it running overnight (accidentally) with measurement data being stored into SPIFFS memory. In the morning, i noticed my OLED display was Frozen - i.e. no values were changing. I restarted the ESP32 and then......... everytime i try to upload any sketch i get errors shown at the end of this post.

I did tons of google searchers and forums, tried all options mentioned everywhere. Tried Arduino IDE, Eclipse Oxygen, platformIO. Tried to skip onboard USB-Serial IC of Wemos and use external USB-Serial adapter. Pressed Boot, Enable buttons, reduced baud rate, changed USB ports, updated drivers, etc. Nothing help and problem remains same. My PC is windows 8.1 64bit. Arduino ide 1.8.1, Eclipse Oxygen, esptool.py v2.1.

But when i program my other ESP32 bare boards or dev boards all are working fine, so i am sure i have not messed up with my PC settings etc.

Could it be that since i was writing to SPIFFS memory (unfortunately in infinite loop - accidentally) it might have just filled up whole memory ? if that is so, there should be some way of Clearing this memory ??? because, if someone does this accidentally again , then each time the ESP32 board will be useless.

Is the flash memory separate from esp32 chip ? can only that be replaced with new IC ?

Is it a hardware issue or software issue ?

Hi Electromania,

Please don't post the exact same thing in multiple places at the same time.

I've replied to you on the Github issue you opened: https://github.com/espressif/esptool/issues/263
