Part Number: MSP430G2553
Other Parts Discussed in Thread: MSP430G2231

Hello everyone,

I am trying assembly language programming in msp430g2553. The code is given below:-

.cdecls C,LIST,"msp430g2231.h"
RESET mov.w #0280h,SP
StopWDT mov.w #WDTPW+WDTHOLD,&WDTCTL

SetupP1 mov.b #001h,&P1DIR
mov.b #000h,&P1OUT
bis.b #008h,&P1REN
bis.b #008h,&P1IE
bis.b #008h,&P1IES
bis.b #008h,&P1IFG

Mainloop bis.w #GIE,SR
nop

P1_ISR;
xor.b #001h,&P1OUT

bic.b #008h,&P1IFG
reti


.sect ".reset"
.short RESET
.sect ".int02"
.short P1_ISR
.end

But I am getting a problem always in the Console Window which is as under:-

**** Build of configuration Debug for project weropisf ****

    I had no issues with the following, CCS v6.2 and TI v16.9.2.LTS.  Make sure that you are using eabi (ELF) output format under Project Properties -> General.

    ;-------------------------------------------------------------------------------
            .cdecls C,LIST,"msp430g2553.h"       ; Include device header file

;-------------------------------------------------------------------------------
            .def    RESET                   ; Export program entry-point to
                                            ; make it known to linker.
;-------------------------------------------------------------------------------
            .text                           ; Assemble into program memory.
            .retain                         ; Override ELF conditional linking
                                            ; and retain current section.
            .retainrefs                     ; And retain any sections that have
                                            ; references to current section.

;-------------------------------------------------------------------------------
RESET       mov.w   #__STACK_END,SP         ; Initialize stackpointer
StopWDT     mov.w   #WDTPW|WDTHOLD,&WDTCTL  ; Stop watchdog timer


;-------------------------------------------------------------------------------
; Main loop here

			mov.b #000h,&P1OUT
			bis.b #008h,&P1REN
			bis.b #008h,&P1IE
			bis.b #008h,&P1IES
			bis.b #008h,&P1IFG

Mainloop 	bis.w #GIE,SR
			nop

P1_ISR;
			xor.b #001h,&P1OUT

			bic.b #008h,&P1IFG
			reti


;-------------------------------------------------------------------------------
; Stack Pointer definition
;-------------------------------------------------------------------------------
            .global __STACK_END
            .sect   .stack

;-------------------------------------------------------------------------------
; Interrupt Vectors
;-------------------------------------------------------------------------------
            .sect   ".reset"                ; MSP430 RESET Vector
            .short  RESET

            .sect ".int02"
			.short P1_ISR
			.end
