Problems when I connect the power supply to the electronic board, with touchgfx.

[fernandogamax]

Good morning community. I have developed a project with touchgfx on a custom electronic board. I am using STM32H735IGT6. The problem I'm having is when I turn the power supply off and on. Sometimes some streaks appear, which can only be fixed by restarting the board. Attached photo and video of the screen. As I said, it happens very rarely. What could be the problem?

Hello @fernandogamax ,

Many possible reasons for that. Could be memory contention for example if you have the LTDC and DMA2D accessing memory at the same time. Have you checked your framebuffer if your values are good?
Also are you able to reproduce your issue while debugging?

Already solved. LTDC configuration problem. Thank you.
