Description
The program following is expected show "3", "6" on Serial, and then blink LED on GPIO 21.
It's OK on board package version 1.0.4, but NG on 1.0.5/1.0.6.
It shows only 3 but not 6, LED on GPIO 21 is not blinking
No debugging messages or core dump etc.
void setup() {
Serial.begin(115200);
Serial.println(__LINE__); //3
delay(10);
Serial.begin(115200);
Serial.println(__LINE__); //6
delay(10);
pinMode(GPIO_NUM_21, OUTPUT);
}
void loop() {
digitalWrite(GPIO_NUM_21,HIGH);
delay(500);
digitalWrite(GPIO_NUM_21,LOW);
delay(500);
}
So, we discussed at teratail.com (Japanese Q&A site) https://teratail.com/questions/326026 , concluded that the countermeasure to Issue #3878 seems to be causing this phenomenon.
I think it's the same phenomenon as #4948 but its impact will be more widespread than just M5Stack.
