How to Blinky onboard LED on a NUCLEO-H755ZI-Q WITHOUT using BSP - only HAL?

[smallkitties3]

Have got the NUCLEO-H755ZI-Q board with the STM32H755ZI chip on it and able to use the BSP package and drive the three LEDs and also perform debugging.

However, whenever tried to build a new project and select STM32H755ZI (not NUCLEO-H755ZI-Q) and configure the project based on the settings in NUCLEO-H755ZI-Q the code does not run. Nor is debugging possible. Also, used the neat Compare Projects tool; but nothing that would impact it stood out.

Have already looked in this online ST-forum and the https://github.com/STMicroelectronics/STM32CubeH7/tree/master and cannot find a simple example of configuring a blinky for a this dual-core or any other - that does not rely on BSP.

All is needed are snapshots of the STM32CubeMX setup.

Thank you and peace to all.

What kind of help do you expect without providing any code nor CubeMX picture? All you need to do is to configure the LED port line as output in CubeMX, then add 4 lines of code to SysTick ISR.
