How to display image from QSPI flash?

[Priyank]

Hi I've been trying to display an image on the GUI using an image (hex array) stored in the QSPI flash (memory mapped). I've taken a look at some of the documentation such as Loading Images at Runtime & Dynamic Bitmaps. 

void LandingView::loadImageFromQSPI(Image& imageWidget)
	{
	    BitmapId bmpId = Bitmap::dynamicBitmapCreateExternal(
			185,
			 43,
	        (const void*)0x90FC0000,
	        Bitmap::RGB565
	    );

	    if (bmpId != BITMAP_INVALID)
	    {
	        imageWidget.setBitmap(Bitmap(bmpId));
	        imageWidget.invalidate(); // To trigger redraw
	    }
	}
FrontendApplication::FrontendApplication(Model& m, FrontendHeap& heap)
    : FrontendApplicationBase(m, heap)
{
    Bitmap::setCache(touchgfxCache, sizeof(touchgfxCache));
}

 When debugging, I keep getting BITMAP_INVALID? I've made sure I'm in memory mapped mode.

Dump the memory content at 0x90FC0000 visible to the MCU, perhaps the first 64 or 128 bytes to a serial terminal, so someone can make an assessment as to whether this is consistent with the described bitmap, or NOT
