unable to recognise LinkerScript symbols in the existing example code.

[saiteja]

how to add the linkerSript memory restrictions to our existing code:-

MEMORY { FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 0x40000 RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x6000 }

and different other symbols present in nrf51_common.ld
