A fatal error occurred: Invalid head of packet
Posted: Fri Sep 06, 2019 12:13 am
Hello everyone,
I have started my adventure with ESP32 and have been having some problems since yesterday. I use Arduino IDE, my ESP32 is powered from bench PSU.
For a few weeks I was able to flash it using Arduino IDE without any issue. ... until yesterday. I have started to encounter following problem:
Sketch uses 193188 bytes (14%) of program storage space. Maximum is 1310720 bytes.
Global variables use 12680 bytes (3%) of dynamic memory, leaving 315000 bytes for local variables. Maximum is 327680 bytes.

A fatal error occurred: Invalid head of packet (0x80)
Only packet address changes. I tried with different module, it is all the same. I have completely no idea what may be wrong. Please note that htere is no connection problem. I can open serial port monitor and see logs e.g.

I have tried two different modules on teo different machines and have completely no idea what may be wrong. I am curious because it had been working for two weeks before yesterday. I do not know what I started to do wrong. Initially I thought I destroyed the module but another one, factory new, behaves in exactly the same manner.
Thank you in advance for any suggestions.
