Hello.

In main.c I try to use some functions from stm32f4xx_hal_tim.c library file, but have the following errors:
...
./src/main.o: In function main': /home/hoverjet/Dropbox/Work/Robotics/Tod/Software/ARM/workspace/tim_2/Debug/../src/main.c:135: undefined reference toHAL_TIM_Base_Init'
/home/hoverjet/Dropbox/Work/Robotics/Tod/Software/ARM/workspace/tim_2/Debug/../src/main.c:143: undefined reference to `HAL_TIM_Base_Start_IT'
collect2: error: ld returned 1 exit status
make: *** [tim_2.elf] Error 1

When you created the project you asked to exclude unused source files. This means that only a small number of library functions were compiled.

Go to the system/src/stm32f4-hal, identify the timer source file and disable the Resource Configuration -> Exclude from Build.

It works. Thank you!
