Hello @CLi.14​  and welcome to the Community :),

I advise you to get inspired from the available TIM_TimeBase examples in the STM32CubeF1 MCU package. This example may help you in the configuration by following the instructions in the readme file.

Also, try to set the optimization level at none in the settings.

I hope this help you.

Thank you.
