- Thu May 23, 2019 2:38 pm #82444 The code below in quotes gives a declaration error on the _SPIFFS_start
It is not defined in your code. Is it a parameter defined in one of the libraries or am I missing something ?
I would really like to use this method and it looks quite nice but I am missing a piece of the puzzle here.
Can you help me , maybe with a bit more code on the declarations and used libraries so I can fix this ?

Kind regards

This is a little late, but it can help somebody, doing a little changes to your code @CodeBreaker and the @martinayotte advice, I tested and this worked for me.

Code: Select allvoid handleSpiffsUpload() {
   
    HTTPUpload& upload = WebServer.upload(); 
   
    if(upload.status == UPLOAD_FILE_START)
    {
        Serial.setDebugOutput(true);
        WiFiUDP::stopAll();
        Serial.printf("Update: %s\n", upload.filename.c_str());       
    }
    else if(upload.status == UPLOAD_FILE_WRITE)
    {
        uint32_t startSpiffs = (uint32_t)&_SPIFFS_start - 0x40200000;
        uint32_t _sector = (startSpiffs + upload.totalSize)/ SPI_FLASH_SEC_SIZE;
        uint32_t data = (uint32_t)upload.buf;
       
        Serial.printf("Location: 0x%x, TotalSize: %d", startSpiffs + upload.totalSize, upload.totalSize);

        if((startSpiffs + upload.totalSize) % FLASH_SECTOR_SIZE == 0 )
        {
            if (spi_flash_erase_sector(_sector) == SPI_FLASH_RESULT_OK)
            {
                Serial.print(", Erased");
            }
            else
                Serial.print(", ErrorErase");
        }
       
        if (spi_flash_write(startSpiffs + upload.totalSize, reinterpret_cast<uint32_t*>(data), upload.currentSize) == SPI_FLASH_RESULT_OK)
          Serial.print(", Writen");
        else
            Serial.print(", ErrorWritten");
        Serial.print("\n");
       // _sector++;
    }
    else if(upload.status == UPLOAD_FILE_END)
    {
        Serial.printf("Update Success: %u\n ... \n", upload.totalSize);
        Serial.setDebugOutput(false);
    }
   
    yield();
}
