Hello !
I’ve made a restart method for my project. Basically, it counts down from 5 to 0 and then does a ESP.restart().
//------------------------- restart_sequence()
void restart_sequence(unsigned int countdown) {
for(int i = countdown; i>=0; i--) {
matrix->clear();
matrix->setFont(NULL);
matrix->setTextSize(1);
matrix->setTextColor(LED_RED_HIGH);
matrix->setCursor(1,1);
matrix->print("Restarting");
matrix->setCursor(20,15);
matrix->print((String)"in " + i);
matrix->show();
delay(1000);
}
server.reset();
delay(900);
matrix->clear();
delay(100);
ESP.restart();
}
I have a flag in void loop() that checks if I issued a restart or not.
void loop() {
if (restartFlag) {
restart_sequence(5);
}
// ...
}
All worked dandy and fine, until I’ve added enableCore1WDT(); to void setup()
void setup() {
Serial.begin(115200);
delay(1000);
enableCore1WDT()
// ...
}
Now, after every restart, the following exception is being thrown:
rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee

SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
And then the Serial Monitor disconnects.
I have no idea why that happens.
Any advice ?
