Boot loop/crash with Espressif ESP32 Arduino core version 2.0.2 #5

Closed ncmreynolds closed 2 years ago

ncmreynolds commented 2 years ago

No video output with Espressif ESP32 Arduino core version 2.0.2. Enters a boot loop with an ledc error. Identical hardware/code works with ESP32 Arduino core v1.0.6, v2.0.0 and v2.0.1.

I'm aware this may actually be an issue with the ESP32 Arduino core that you cannot fix, but thought I'd raise it here as I don't have the background on the internals of the composite video code to be sure.

I agree this may be something with the Arduino code, but I can help you come up with a test case that demonstrates the problem. Can you try the following code and see if it reproduces the problem:

void setup() {
  Serial.begin(115200);

  Serial.printf("Initializing peripherals");
  // put your setup code here, to run once:
  periph_module_enable(PERIPH_I2S0_MODULE);
  rtc_clk_apll_enable(1,0x46,0x97,0x4,1);
}

void loop() {
  // put your main code here, to run repeatedly:
 Serial.printf("Looping");
 delay(1000);
}
