Reply To: ESP32 port of 2.1.9 firmware

Hi,

Thanks for all the effort of porting to the ESp32.

I have an ESp32 WROOM with external OLED on pins SDA 21 and SCL 22. Everything compiled without errors, but after it uploaded, it would only continually reboot and never start.

I have modified a small piece of code in mainArduino

The Original Code:

#if defined(ESP32)

  int i;
  unsigned int pin_list[] = ON_BOARD_GPIN_LIST;
  for( i=0; i<7; i++ ){
    if(pin_list[i] !=255){
      pinMode(i, OUTPUT);
      digitalWrite(i, ~STATION_LOGIC);
    }
  }

Changed to this:

#if defined(ESP32)

  int i;
  unsigned int pin_list[] = ON_BOARD_GPIN_LIST;
  for( i=0; i<8; i++ ){
    if(pin_list[i] !=255){
      pinMode(pin_list[i], OUTPUT);
      digitalWrite(pin_list[i], ~STATION_LOGIC);
    }
  }

#endif

I believe the original code was potentially setting pins 6 and 7 which on this version of ESP32 are connected to the integrated SPI flash, and causing the crash reboot cycle.

It now works perfectly for me – hope it helps for someone else
