Hey everyone! I was using touch GFX Designer to create a project for the STM32F769I-DISCOVERY and after generating the code and testing both simulator and target, I proceeded to open the IAR project but this errors show up when debugging:

When debugging on GFX Designer , the display in the start shows up with some errors but when I press the display button it stars working as shown on the simulator.0690X00000AryfKQAR.jpg

after generating the code and moving to IAR, the following warnings were displayed:

The controller shows an inconstant behavior:

0x90000000 is the start of QSPI. You need to program the QSPI using ST-Link or STCubeProgrammer.

The warning you're getting is from IAR not having a solution to program that range 0x90000000 ->

How did you create this project? If you have ST-Link installed and use the STM32F769-DISCO Application template from the TouchGFX designer then "run target" should build with arm-gcc and program both internal and external flash using ST-Link and appropriate flash loader.

I have exactly the same thing with touchGFX "Run target"

Why first screen is corrupted and works after a screen update ?
