IDF (Arduino) OTA problem

[marcelwinter04]

I'm trying to get the OTA SD Card example working. This thing worked with the Arduino IDE unfortunately there is no option to change the menuconfig with the arduino ide. So now im trying the same example with the esp idf but with the arduino component.

#include <FS.h>
#include <SD_MMC.h>
#include <Update.h>

void rebootEspWithReason(String reason){
    Serial.println(reason);
    delay(1000);
    ESP.restart();
}

void performUpdate(Stream &updateSource, size_t updateSize) {
   if (Update.begin(updateSize)) {      
      size_t written = Update.writeStream(updateSource);
      if (written == updateSize) {
         Serial.println("Written : " + String(written) + " successfully");
      }
      else {
         Serial.println("Written only : " + String(written) + "/" + String(updateSize) + ". Retry?");
      }
      if (Update.end()) {
         Serial.println("OTA done!");
         if (Update.isFinished()) {
            Serial.println(Update.hasError());
            Serial.println(Update.isRunning());
            Serial.println(Update.rollBack());
            rebootEspWithReason("Update successfully completed. Rebooting.");
         }  
         else {
            Serial.println("Update not finished? Something went wrong!");
         }
      }
      else {
         Serial.println("Error Occurred. Error #: " + String(Update.getError()));
      }

   }
   else
   {
      Serial.println("Not enough space to begin OTA");
   }
}

void updateFromFS(fs::FS &fs) {
   File updateBin = fs.open("/update.bin");
   if (updateBin) {
      if(updateBin.isDirectory()){
         Serial.println("Error, update.bin is not a file");
         updateBin.close();
         return;
      }

      size_t updateSize = updateBin.size();

      if (updateSize > 0) {
         Serial.println("Try to start update");
         performUpdate(updateBin, updateSize);
      }
      else {
         Serial.println("Error, file is empty");
      }

      updateBin.close();
    
      // whe finished remove the binary from sd card to indicate end of the process
     // fs.remove("/update.bin");      
   }
   else {
      Serial.println("Could not load update.bin from sd root");
   }
}

extern "C" void app_main()
{
    initArduino();
    pinMode(4, OUTPUT);
    digitalWrite(4, HIGH);
    
	Serial.begin(115200);
	
    if(!SD_MMC.begin()){
        Serial.println("Card Mount Failed");
        return;
    }
    uint8_t cardType = SD_MMC.cardType();

    if(cardType == CARD_NONE){
        Serial.println("No SD_MMC card attached");
        return;
    }

    Serial.print("SD_MMC Card Type: ");
    if(cardType == CARD_MMC){
        Serial.println("MMC");
    } else if(cardType == CARD_SD){
        Serial.println("SDSC");
    } else if(cardType == CARD_SDHC){
        Serial.println("SDHC");
    } else {
        Serial.println("UNKNOWN");
    }

    uint64_t cardSize = SD_MMC.cardSize() / (1024 * 1024);
    Serial.printf("SD_MMC Card Size: %lluMB\n", cardSize);

    updateFromFS(SD_MMC);

    while (1) {
        vTaskDelay(1);
    }
}

But when i build this project i get following error message

Does anybody knows what the problem may be?

@marcelwinter04 How did u get it working on the arduino IDE? I'm getting a core panicked error.
Using https://github.com/espressif/arduino-esp32/blob/master/libraries/Update/examples/SD_Update/SD_Update.ino example.

Could you please help me figure what's going wrong?

@KARTIK-eng on the arduino ide it worked without doing anything.

Which board are you using?
