CubeMX Sys Timebase Source does not generate htim3 or xxx_timebase_tim.c

[MRobe.1]

Hi

I have found that I have to "mess with" the Sys -> Timebase setting to get Generate Code to create the file stmf4xx_hal_timebase_tim.c.  I have no other timers enabled, just the Sys -> Timebase setting which is set to TIM3.

When I say "mess with" I mean this:

• Generate Code does not generate the htim3 code nor the _timebase_tim.c file when Sys -> Timebase is, first, set to TIM3
• I need to switch between timebase timers and generate code repeatedly, probably with multiple CubeMX restarts and even a PC restart
• Somehow, I do not know why, it eventually works but I get the C file with htim3 declared

Once it has worked I find that regenerating code works every time.  It is just that getting it to generate code correctly the first time is a problem.

It should work first time.  It does not.  I am generating code for MDK V5.

Hello @MRobe.1, 

Could you please specify the exact steps that led you to this issue? 

I generated a project from scratch using STM32CubeMX and only enabled system wakeup and chose TIM3 as the timebase source, and I didn't need to change anything as stm32f4xx_hal_timebase_tim.c is generated.

Hi Sarra

I did not enable System Wakeup (I am, only, using TIM3 for RTX2).  Let me clean out the project and attach the IOC once confirming it repeats with me.

Hi Sarra

I have tried to repeat and have failed!  Given it was a simple project (none of my code) and it was the generated code that was complaining about htim3 being missing I cannot see that I dreamt it!  I suspect there was a clash with another setting which I have since, unknowingly, resolved.  Anyway, thanks for quick response.
