-    /// This function requires careful management of the memory being written to. Writing to a

-    ///
-    /// Ensure that the data being written is compatible with the current contents of the flash

-    /// - `offset`: The offset within the DFU partition where the data will be written. Must be

-    /// - `data`: A reference to the slice of bytes to be written. The length of the data must not
-    /// exceed the partition size and must follow the flash's alignment requirements.
-    ///
-    /// # Returns
-    ///
