Abstract: PURPOSE: A method for sharing an FRIA(Frame Relay Interface Assembly) and a BSP(Board Support Package) capable of sharing the BSP in a BSS(Base Station Subsystem) of a mobile communication system is provided to prevent the waste of a memory by copying the BSP to a memory region shared between an MP(Main Processor) and a PC(Protocol Conversion) when initializing a hardware and performing the hardware initialization in the FRIA without composing a specific flash ROM in a PC unit. CONSTITUTION: A BSM(Base Station Management) starts a pSOS(302), and initializes an MP unit and PC units(304). The MP unit and the PC units check a port size of a flash ROM(306). If the port size of the flash ROM is 8 bits(308), the MP unit runs a BSP code corresponding to the MP unit among BSP codes stored in an MP unit flash ROM and initializes hardware devices connected to the MP unit(310). If the port size of the flash ROM is 16 bits(312), the PC units run a BSP code corresponding to the PC units among BSP codes copied in the DPRAMs and initialize hardware devices connected to the PC units(314).
