New with STM32H7

[victorsj]

Hello community! 

I'm trying to start a project to test a new board Nucleo-H755ZI-Q, but i don't now how dual nucleo works and if is a board problem, code problem or a debug config problem.

Follow some ST docs tutorial or Youtube tutorial give the same error: The CM7 and CM4 debug open, but if i click on run debug, the project debug close and cube IDE back to the code editor.

Here is the clock config print:

Clock config page 1

Clock config page 2

Here is the pinout config:

pinout config

 The code CM7 and CM4 is just LED blink on infinite loop:

/* CM7 code */ 
 while (1)
  {
	  HAL_GPIO_TogglePin(LD1_GPIO_Port, LD1_Pin);
	  HAL_Delay(250);
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */

/* CM4 code */ 
  while (1)
  {
	  HAL_GPIO_TogglePin(LD2_GPIO_Port, LD2_Pin);
	  HAL_Delay(500);
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */

 The Debugger CM7 config:

CM7 Debug page1

CM7 Debug page2

The Debugger CM4 config:

 CM4 Debugger page1

CM4 Debugger page2

 Startup config:

CM7 Startup

CM4 Startup

If someone has a complete exemple with IOC and code to blink leds on Nucleo-H755ZI it can help me so much.

Hello @victorsj and welcome to the Community :),

Which STM32CubeIDE are you using?

Are you following Getting started with projects based on dual-core STM32H7 microcontrollers
in STM32CubeIDE application note?

This application note describes how to get started with projects based on STM32H7 Series dual-core microcontrollers in the STMicroelectronics STM32CubeIDE integrated development environment. For that I recommend you to take a look at this application note and precisely section 3 Debugging.

May this post can help you.

Thank you.

Hello!

Thank you for your reply.

Yes, i followed this application note to debug with GDB server and to debug with open OCD too. The two ways don't work yet. I did exactly how this video tutorial show too. 

The Cube IDE is  STM32CubeIDE 1.14.1

Hello @victorsj ,

Could you please try to uncheck the ST-LINK S/N in the Debugger configuration: 

Debugger CM7 config:

Debugger CM4 config:

Please make sure in "CM7 startup" that the "Download" of "Debug\agora_vai_test_CM4.elf" is "true" as shown in the below figure.

Please make sure in "CM4 startup" that the "Download" of  "Debug\agora_vai_test_CM4.elf" is "false" as shown in the below figure.

I tested your project using Nucleo-H755ZI-Q and STM32CubeIDE1.14.1 based on this video Dual Core Debugging on STM32H7 with STM32CubeIDE and it works correctly.

I hope this help you!
