CubeMx Generates Garbage Init Code??

Using CubeMX V4.7.1 I get garbage initialization code for RTC.c when I request initialization be generated as .c.h file pairs.

Simple demo case:

Start CubeMX

New Project

Select STMf103C8Tx as target

Under Pins Select RTC-> Activate Clock Source.

Under Project settings:

   Project Name: Test

   Location: C:\Temp\

   Under Code Generator Tab:

         Check Generate peripheral initialization as pair of .c/.h files

Leave everything else at defaults.

Generate the code and look at rtc.c. It's not C source code. Eg.

/* RTC init function */

void MX_RTC_Init(void){#n#t#t/**Initialize RTC Only #n#t#t*/#thrtc.Instance = RTC;#thrtc.Init.AsynchPrediv = RTC_AUTO_1_SECOND;#thrtc.Init.OutPut = RTC_OUTPUTSOURCE_ALARM;#tif (HAL_RTC_Init(&hrtc) != HAL_OK)#t{#t#t_Error_Handler(__FILE__, __LINE__);#t}

Followed by what looks like a lot of Java error messages.

Looks like a CubeMX bug to me. If I leave the init stuff in main, it works OK.

Thanks for the quick response. V 4.25.0 fixes the above issues, but there are still problems. Using the above test case and generating code for TrueStudio (Compile under root unchecked), the code will not build without errors. E.g. :

..\..\..\Src\rtc.c:73:5: warning: implicit declaration of function 'LL_PWR_EnableBkUpAccess' [-Wimplicit-function-declaration] LL_PWR_EnableBkUpAccess();

..\..\..\Src\rtc.c:75:5: warning: implicit declaration of function 'LL_APB1_GRP1_EnableClock' [-Wimplicit-function-declaration]  LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_BKP);..\..\..\Src\rtc.c:75:30: error: 'LL_APB1_GRP1_PERIPH_BKP' undeclared (first use in this function)     LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_BKP);                            

If I generate code for the test project with the peripheral inits in main(), the project will then build without error.
