Hello ST members
I've been having a problem with my STM32H745I-DISCO Board after my co-worker was trying to learn how to use and create projects with it.
It was a simple project of using a digital button conected to the board via jumper and a potentiometer. it used sampling from gui to make the conection between the information that came from the model to the view.
He used the option of solve clock issues in cubeMX to configure the analog ports.
After that, the screen was blank, I tried to upload my previously working projects to the board but nothing changed. I tried erasing the flash and external memory via cube programmer, nothing changed.
There were no build problems, and when flashing the project via touchgfx, no problems were announced in the monitor too.
Then, I tried uploading the exemple project from ST called LTDC_Display_2Layers, and it worked perfectly.
After that, I tried uploading the full demo for my board STM32Cube_Demo-STM32H745I-DISCO-V1.0.0_FULL.hex, it also worked perfectly.
After that, I tried flashing again my old projects, but they still wouldnt work.
I am a begginer, so I am not very knowledgeable about this boards. What could the error be?
From what I read, it could be a clock issue or a sdram issue of some kind.
Is there any way I can reset my board to its previous state, so it can work again?
