GENERATE CODE error, unknown type name 'HAL_StatusTypeDef'

[Snowcone_engineer]

Eval board used: Nucleo-U385RG-Q 
Software tools:
STM32CubeIDE Version: 2.0.0 Build: 26820_20251114_1348 (UTC)
STM32CubeMX Version: 6.15.0

The provided project for the eval board builds without errors.
But when I modify the MCU to add a GPIO or I2C using STM32CubeMX,
multiple build errors are generated after using "GENERATE CODE" command.

These errors are:

unknown type name 'HAL_StatusTypeDef'
unknown type name 'HAL_LockTypeDef'

Although these definitions are defined in the following *.h file:
stm32u3xx_hal_def.h

/**
* @brief HAL Status structures definition
*/
typedef enum
{
 HAL_OK = 0x00,
 HAL_ERROR = 0x01,
 HAL_BUSY = 0x02,
 HAL_TIMEOUT = 0x03
} HAL_StatusTypeDef;

/**
* @brief HAL Lock structures definition
*/
typedef enum
{
 HAL_UNLOCKED = 0x00,
 HAL_LOCKED = 0x01
} HAL_LockTypeDef;

Apparently, the errors are created from define guards not allowing other files
to access and use the “typedef enum HAL_StatusTypeDef and HAL_LockTypeDef in stm32u3xx_hal_def.h.

To correct the problem:
I had to move HAL_StatusTypeDef and HAL_LockTypeDef defines To: stm32u3xx_hal_conf.h

Unfortunately, each to I modify the MCU pin definition or add a pin assignment with STM32CubeMX
and regenerate the code using "GENERATE CODE", the same errors are created after a build is started.

It seems there is a bug in the STM32CubeMX when using the "GENERATE CODE".

Please provide the IOC file and project code you used to generate the issue.

 

I'm able to add a I2C peripheral and GPIO pin and generate code without issue.

Thanks for trying to reproduce my issue.

Attached is the IOC file used in the project and build. I hope this will help alone.

Sorry about not including the whole project, it's a bit large and include some proprietary data.

If this isn't enough to solve the problem, I'll just use the work around for now. It may not be a problem when I change the project from the U385 eval board to my own PCB design.

Hi @Snowcone_engineer 

Would you mention which Cube firmware version are you using as well? Is it V1.2.1?

[Snowcone_engineer]

I'm not sure what you mean by "Cube firmware version". The following are the tool versions that I used.

STM32CubeIDE Version: 2.0.0 Build: 26820_20251114_1348 (UTC)
STM32CubeMX Version: 6.15.0

Thanks.

This IOC files generates code that compiles with no errors.

You're not on the latest versions, it's possible that could be an issue.

> Sorry about not including the whole project, it's a bit large and include some proprietary data.

The problem about not showing the project is that the error can't be reproduced. If you can generate a toy problem that gives the same error, try that. Otherwise it's difficult to debug code without seeing the code.

My crystal ball says your include files are wrong or out of order.

 

You should only ever include "stm32u3xx_hal.h"
