Hi @senthil​ ,

I am using the same example and I am able to compile it without issue using Keil.

I suggest you to make sure that:

• the whole package is extracted successfully without missing any file
• "Floating Point Hardware" is used (Single Precision) in IDE options
• following preprocessor defines are there: USE_HAL_DRIVER,STM32F429xx,USE_STM32F429I_DISCO,ARM_MATH_CM4
