Hello Praveen. Please confirm the tools you are using. If you are indeed using the Keil C51 toolchain then that is the issue. The LPC1768 is the ARM Cortex CPU architecture and NOT C51 (ie. 8051 series). The LPC can spin circles around most 8051 devices. You will need to download a different version of the toolchain from Keil to support your target CPU (Cortex CPUs). Respectively, the C51 toolchain will not have any knowledge of the LPC1768 architecture.
