Implementation Keil RTOS-RTX in CubeMX project

Create CubeMX project with STM32F429 Discovery

In NVIC set prioryti of System tick timer and Generate Code in MDK v5

Open project in Keil (ver 5.18)

In Manage Run-Time Environment set Keil RTX

When checked Keil RTX and do not mention on yellow and Validation Output
