Undefined reference to 'HAL_RTC_Init' problem

[지한.1]

Hi, I want to use the RTC. ( Use STM32F429ZI Discovery board )

​

So, I set

1. RCC-> High Speed Clock Cystal/Ceramic Resonator

RCC-> Low Speed Clock Cystal/Ceramic Resonator

2. Clock Configuration -> RTC Clock Mux -> LSE

3. Pinout & Configuration -> Timers -> RTC -> Active Clock Source

4. Generate Code and Build project but, failed

​

Can you help me to solve this problem?

Hello @지용 한​ ,

Thank you for reporting your issue, I will try to help you on it :) .

First on my side, I started a new project following the same steps as you and it works properly. You can try it on your side with my project attached. I am using STM32CubeIDE V1.7.0.

Now let's try to understand your issue, please provide me more details on your project.

• What's IDE do you use ? (STM32CubeIDE, EWARM ...)
• What's your version of STM32CubeMX ? Sometimes just by using the latest version can solve your issue.
• Are you using all the includes generated by STM32CubeMX ?

Thank you for your responses.

Hi,

1. I used STM32CubeIDE ( Version 1.8.0 )
2. Maybe STM32CubeMX version is 6.4.0.xxxxxx
3. I generate code, STM32CubeIDE.

​

I think, the problem is importing from TouchGFX to STM32CubeIDE.

​

TouchGFX Desinger version is 4.18.1

​

The order of execution is as follows.

​

1. In TouchGFX, Make project and generate code. ( ex. Project name is MyTemplate. )
2. In STM32CubeIDE, File -> Open Proejct File system.
3. In STM32CubeIDE, Import Project from File System or Archive -> Directory -> Find MyTemplate proejct and Finish
4. In STM32CubeIDE, Click STM32F249I-DISCO( in STM32CubeIDE ) and success build
5. In STM32CubeIDE, Click STM32F429I_DISCO_REV_E01.ioc and rename MyTemplate.ioc.
6. In STM32CubeIDE, Open MyTemplate.ioc file and RCC setting. ( HSE -> Crystal/Ceramic Resonator, LSE -> Crystal/Ceramic Resonator )
7. In STM32CubeIDE, RTC check Active Clock Source.
8. In STM32CubeIDE, Save the MyTemplate.ioc file and Click STM32F249I-DISCO( in STM32CubeIDE ) icon build project.
9. Undefined reference to 'HAL_RTC_Init'

I ran a few test( DAC, ADC, UART ..), but all failed with similar problem.

( Undefined reference to 'HAL_DAC_init' ...)

​

Can you help me, how to import from TouchGFX to STM32CubeIDE?

Hi @지용 한​ ,

Thank you for your detailed description.

By following your steps I had the same issue, but I find a workaround that can help you :) . Before that please have you followed those installation steps.

Please can you try that on your side :

1. In TouchGFX, Make project and generate code.  ( ex. Project name is MyTemplate. )
2. Do to the TouchGFXProject directory C:\TouchGFXProjects\MyTemplate\STM32CubeIDE
3. Open the project .project, that will open STM32CubeIDE and your IDE should look like that.
4. Go to C:\TouchGFXProjects\MyTemplate\ open the file STM32F429I_DISCO_REV_E01.ioc with STM32CubeMX. I am using the version 6.3.0.
5. In STM32CubeMX, Open MyTemplate.ioc file and RCC setting. ( HSE -> Crystal/Ceramic Resonator, LSE -> Crystal/Ceramic Resonator )
6. In STM32CubeMX, RTC check Active Clock Source.
7. In STM32CubeMX, generate code.
8. In STM32CubeIDE, your project should be updated, build it.

That should solve your issue for now.

I will check internally why we can't use STM32CubeIDE to update the project.

Best Regards

I understand what's problem. 

If you take look at the hierarchy under driver/stm32f4xx_HAL_Driver. 

You will notice hal file related to rtc not present. You have to link this file path so that this file will be available.

And after that compile code.
