    hello, I am new to qt and trying to access flash memory of my board to store data given by user through the gui.
    the board has an ARM-cortex A7 on it and the yocto project is used for linux distribution.
    Does anyone know how I can access the flash memory, manage partitions and read/write data ? thank you

      @IAEnidi Managing partitions is outside of Qt, you will need to do it on system level (how exactly depends on the OS). Accessing the data should be just like on any other system if you have partitions which are mounted in the file system.

        @jsulm hello,
        Actually, I am going to implement a login app so I need to collect user data through the gui and then go store them in flash memory using QT. I don't see how to do it without QT if all my code is managed by QT, thank you

          @IAEnidi
          @jsulm does not mean you cannot do it from within a Qt application. He just means it is outside of the scope of what Qt provides for you. You would just find out how to do whatever about the flash with system/OS calls in C or C++ and put that code into your Qt project.

            @IAEnidi Again: is your flash memory partitioned and mounted?
