Touchgfx 4.13 and Cubemx 5.5 project creation

Hi,

I use the .ioc file in STM32F746-DISCO v.3.0.0 project, import it to CUBE IDE and used the option to create a project form ioc file. But even i compiled and run in in stm32f746 board, nothing happens. Any reason for this, or whats the fix. My end goal is to make it compatible with a display of 800x480.

But did you actually program the flash with the contents of this region? You require an external flashloader configured from either ST-Link or STCubeProgrammer - Or through CubeIDE.

"Nothing happens" - Can you elaborate?

Nothing comes to display. I created a gui in touchgfx. Build it using new cubeide but when I run it, nothing comes to the display. ​there are no errors or hard faults comes when running.

I got the code to work after comparing both cubemx generated code and touchgfx generated code. There were some missing code areas where in the cubemx generated project. Now having another problem where background images dosent show properly. Can you provide me any guidance on it happens?

"missing" code areas are intentional - They're not the responsibility of CubeMX. At least i'm hoping that you're talking about USER CODE sections related to SDRAM and QSPI.

As for your canvas, there may be some issues with it:

* Anything that isn't covered by something (box, image, etc) is basically just garbage framebuffer memory.

* Are images referenced in QSPI? Did you program it?

Hi Martin. Thanks for getting back to me. I use the default images provided from touchgfx and it's in quadspi region. I used the linker modifications done in the example project generated from touchgfx for f746​

But did you actually program the flash with the contents of this region? You require an external flashloader configured from either ST-Link or STCubeProgrammer - Or through CubeIDE.

Thanks. That was the issue. It worked after i added the flash loader. :grinning_face:

Great! :)
