Can't program STM32H745-Disco

[Durga_Prasad]

Hi,

               I'm using STM32H745-Disco kit. facing some issues while testing, Initially able to configure in STM32Cube IDE software, STm32Cube programmer and STM32CubeMX software's tool without any issues. Now working on testing an hall effect sensor with STM32H745 board, here i'm able to write code in IDE and build the code without any errors, also .elf file is generated successfully. but when i connect STM32 board and try to flash the code, getting issues, not able to flash the code correctly, not understanding what i'm missing here.

Can you please help me, how to resolve my issues and reset my STM32H45 developer board into Default settings/Configurations.

Note: I verified connection in STM32cube programmer tool, i can connect via ST-link and tried Full Chip erase, able to erase but my STM32 board just turns on and shows White color Display with blank Screen. Please refer attached snapshot.

So what, exactly, happens when you try to flash the code?

Describe your process in detail, and any error messages that you see.

Were you able to program using CubeProgrammer?

Hello @Durga_Prasad ,

Checking the power configuration of your firmware and the board and ensure that the board is receiving adequate power. Maybe, insufficient power supply can cause issues with flashing the code.

The screen doesn't magically work, you have to have code to specifically initialize it and provide a frame buffer.

If you code only manages the HALL sensor, and doesn't nothing about the screen,it will stay in this white state.

Can you use a UART and the ST-LINK VCP to get diagnostic and telemetry data out?

Can you program the original demo back on the board, or an example that actually uses the screen?

There's not a button to get back to delivered condition, you need to re-apply a firmware
