Description

Hello hope you are doing fine,
i am facing a problem with my esp32 ,

after downloading successfully the firmware bin file ,the system crashs time to time when it tries to start update " OTA " from a binary file located in the filesystem "SPIFFS"

Error
assert failed: xQueueSemaphoreTake queue.c:1554 (!( ( xTaskGetSchedulerState() == ( ( BaseType_t ) 0 ) ) && ( xTicksToWait != 0 ) ))

Sketch

void updateFromFS()
{

  // Open the file for reading
  File file = SPIFFS.open("/update.bin");

  // Check if the file is available
  if (!file) {
    Serial.println("Failed to open file for reading");
    return;
  }

  Serial.println("Starting update...");

  // Get the file size
  size_t fileSize = file.size();
  // Start the update process
  if (!Update.begin(fileSize)) {
    Serial.println("Cannot do the update: Not enough space or other start error");
    file.close(); // Close the file early to free resources
    return;
  }

  // Perform the actual update
  size_t written = Update.writeStream(file);

  // Check if the written size is less than expected
  if (written != fileSize) {
    Serial.println("Written less data than expected");
    // Abort the update to avoid a possible corrupt firmware
    Update.abort();
  }

  // If the update was successful, the microcontroller will reset
  if (Update.end()) {
    Serial.println("Successful update");
  } else {
    Serial.println("Error Occurred: " + String(Update.getError()));
    Update.abort(); // Abort the update
    file.close(); // Close the file before returning
    return;
  }

  // Close the file after the update
  file.close();

  // Notify the user that the device will reset
  Serial.println("Reset in 4 seconds...");
  delay(4000);

  // Restart the microcontroller
  ESP.restart();

}

It looks like you need to dereference the pointer in writeStream. You want the data, not the file handle.

It looks like you need to dereference the pointer in writeStream. You want the data, not the file handle.

the function writeStream takes a reference to a Stream object as its parameter. When i call writeStream with my File object (file), i think i'm already doing it correctly, as long as File is derived from Stream or is compatible with it. In the context of Arduino and similar environments, File usually inherits from Stream, so i should be good to do that.

so i think i don't need to pass a pointer or a data string directly to writeStream. The function expects a Stream reference, and the File object represents a stream of bytes from the file /update.bin. This means the function will read the bytes from this file stream

Unless I’m mistaken ...

The semaphore error might indicate a timeout, but you would not get a memory corruption from a timeout (you would get a useable backtrace). If you are having timing issues, you may need to chunk the data yourself so that you can put a breather in there every few seconds.
