I am compiling my project with arduino ide, it worked fine for 2 weeks now, but snce 3 day ago, i am getting this error when the device wakes fom deep sleep or restarts after working for a few hours:

error: pll_cal exceeds 2ms

after getting this error, the wifi will not connect ever again, no matter the deep sleeps after that or software resets…

commands like abort() or ESP.restart() do not work to fix this issue, only when i press the hardware reset button.

did i get a faulty board, or is this a software issue?

a bit of the neccessary code:

setup
///
Serial.begin(115200);
analogReadResolution(12);

#ifdef DEVELOPMENT
delay(1000);
#endif

General::InitDevice()

////

RTC_DATA_ATTR unsigned long bootCount = 0;
RTC_DATA_ATTR unsigned long requestFails = 0;

void General::InitDevice() {
Serial.println("---------------------");

  Serial.print("bootCount: ");
  Serial.println(bootCount);

  Serial.print("requestFails: ");
  Serial.println(requestFails);

  if (requestFails > 2) {
abort();
  //ESP.restart();
  }

Serial.println("Init Device");
  preferences.begin(PROJECT, false);

  ++bootCount;

  String uid = preferences.getString("uid", "");
  if (uid.length() <= 0) {
uid = General::GenerateUUID();
  preferences.putString("uid", uid);
  }

Serial.print("uid: ");
  Serial.println(uid);

  String hostname = PROJECT + String("-") + uid.substring(0, 8); //project name + first 8 chars from uid
  WiFiClass::setHostname(hostname.c_str());

  Serial.print("SSID: ");
  Serial.println(WIFI_SSID);

  uint8_t wifiFails = 0;

  WiFiClass::mode(WIFI_STA);
  //WiFi.setAutoReconnect(true);

  WiFi.begin(WIFI_SSID, WIFI_PASS);
  while (WiFiClass::status() != WL_CONNECTED) {
delay(500);
  Serial.print(".");
  if (wifiFails > 24) {
requestFails++;
  General::PutToSleep();
  }
wifiFails++;
  }
Serial.println("Connected!")

///

void General::PutToSleep(unsigned long microSeconds) {
uptime += millis();
  General::UpdateStatus(DeviceState::SLEEP);

  //WiFi.setSleep(false);
  WiFi.disconnect();
  ESP.deepSleep(microSeconds);
}
