MDK & HAL & __attribute

I'm using the STM32CUBEMX which generates HAL code and keeps my code within defined comments. BUT, I need to define an __attribute statement BEFORE a HAL generated function header, but there is no /* USER CODE .. */ place to hold these statements so they get wiped with every STM32CUBEMX project update. Any solutions??

Many Thanks, Glenn

Its a bit of a sledgehammer approach, but it works in some cases;

And i apologized in advance to all those it really offends! LOL

Suppose you have something like this, and you want to change or add something in the 3 init calls;

 /* USER CODE BEGIN SysInit */
 /* USER CODE END SysInit */
 /* Initialize all configured peripherals */
 MX_GPIO_Init();
 MX_TIM2_Init();
 MX_TIM1_Init();
 /* USER CODE BEGIN 2 */
 /* USER CODE END 2 */

you can undefine a section of Cube Code between user code sections;

regenerating with Cube will leave your tweaks in place.

 /* USER CODE BEGIN SysInit */
 MX_GPIO_Init();
 MX_TIM2_Init();
 //add new thing here or add attribute to something
 MX_TIM1_Init();
#ifdef nothing
 /* USER CODE END SysInit */
 /* Initialize all configured peripherals */
 MX_GPIO_Init();
 MX_TIM2_Init();
 MX_TIM1_Init();
 /* USER CODE BEGIN 2 */
#endif
 /* USER CODE END 2 */

Where you have important work build from a sandbox and merge back in changes from a CubeMX build iteration. Or automate patching with a script as appropriate.
