STM32H745 Disco, Simple Hello World and LED Blink

[DDilw.1]

I have worked with several STM32 Nucleo and Discovery Boards. My typical starting point is to print "Hello World" and blink an LED with from a HAL project. The HAL/IOC part is working as expected. I am thinking I am missing some dual-core hardware permission setting?

The code looks right, single steps, but I am seeing neither UART or LED activity. I was able to get one of the (converted) demos to access the UART and LED, so the board is working.

How do I get simple Hello World and Blink LED working, for example:

> A simple example that minimizes extra(neous) features

> Documentation (or clues) to related development techniques

Thanks,

Hi @DDilw.1​ ,

I advise you to follow the GPIO_EXTI example. This may help you to print "Hello world" and blink an LED.
