Touchgfx Simulator Crashes After Screen Rotation and Change Screen

[farukisiker]

// To regenerate crash, follow these steps
// In simulator mode
// 1. Rotate screen
        	if (touchgfx::HAL::getInstance()->getDisplayOrientation() == touchgfx::ORIENTATION_PORTRAIT)
        	{
        		touchgfx::HAL::getInstance()->setDisplayOrientation(touchgfx::ORIENTATION_LANDSCAPE);
        	}
        	else
        	{
        		touchgfx::HAL::getInstance()->setDisplayOrientation(touchgfx::ORIENTATION_PORTRAIT);
        	}
// 2. Go to other screen
application().gotoScreen2ScreenCoverTransitionEast();
// Crash

There is probably a bug after rotating screen in simulator mode.

Additionally, in debug mode (on hardware) when I apply screen rotation, it is not validated. If I change screen to another one, rotation is applied but with glitches in pixels.

Ah, sorry. I forgot to change screen - now the icons are not drawn correctly.

Hi @farukisiker 

I created a simpler app to find solution to this problem - open project in GfxDesigner and F5.

Press key small 'L' and then 'r'.

Hi @ferro ,

I have tried gfx4260_rotate project that you shared. There is error when I rotate the screen. You can check it in video that I shared here!

[ferro]

Thanks for the video. For some reason I am not able to place images here at the moment.

"There is error when I rotate the screen."

Yes, the error that causes glitches in you app. I think. I wonder how it runs on a board. I think this is not expectedbehaviour. As if new display orientation is not properly treated when changing screen. Hm, not sure what is next.I've never worked with run time screen rotation.

@ferro you can examine how it makes a problem on hw.

[farukisiker]

Hi again @ferro I found another bigger problem with rotation. If I add a mjpeg (avi) format video and use rotation feature, it stucks at DMA2D_XferErrorCallback.

By the way in this project XSPI channels are swapped with same pin configuration.

[ferro]

Yes, I observed that behavior when I ran your app.

However, as I mentioned, I wanted to create a very simple application to observe this behavior in isolation. It is difficult to determine what is happening in your app because many things are going on.

[ferro]

Aha, no idea what this means.
I suspect some well-seasoned Gfx veteran is already observing this thread and will join the discussion soon.
Regrettably, I cannot devote more time this week. Sorry. I would start with my example - that should work as expected.

[farukisiker]

Thanks, I will be waiting solution from veterans then.
