How can I fix this problem?

Answer

The Keil RTX51 Tiny Real-Time kernel is included in the PK51 Professional Developer's Kit.

 

Using the LX51 linker, add the RTX51TINY directive to specify that the project being linked is a real-time application that uses the RTX51 Tiny Real-Time Operating System. This can be done in the Properties of the current project in Simplicity IDE: Settings > Keil 8051 Linker > Miscellaneous > Additional Flags. Finally re-build the project again.
