Hello,
I am doing bringup to touchGFX based costum LCD controller using STM32H735 MCU connected to the LCD with Parrallel RGB using LTDC.
Currently the application not returning from the tick() function called from backPorchExited().
The stuck occers from the backPorchExited() first call.
What could be the reason for such problem?
Explanations regards the expected behaviur of tick() call from backPorchExited() will be highly appreciated.
Thank you!

Solved!
The problem caused due to flash memory mapping problem.
The DMA2D tried to read from non existing address therefor the transaction never ended.
After fixing the flash memory mapped mode the GUI start working.
