The MSP430 gcc toolchain

Assuming an ubuntu machine install following packages and test them by building a simple led blinking program as listed below.

• Install gcc-msp430, the GNU compiler collection for msp430 https://launchpad.net/ubuntu/+source/gcc-msp430 or https://www.ti.com/tool/MSP430-GCC-OPENSOURCE
  • sudo apt-get install gcc-msp430
• Install msp430mcu, which ships specs files, headers and linker scripts for msp430 targets https://launchpad.net/ubuntu/+source/msp430mcu
  • sudo apt-get install msp430mcu
• Install msp430-libc, which is a C library for msp430 devices https://launchpad.net/ubuntu/+source/msp430-libc
  • sudo apt-get install msp430-libc

• Test tool-chain by compiling a simple program, which blinks two Leds
  • msp430-gcc -mmcu=msp430g2553 blinkled.c -o blinkled.elf

• Blinkled.c:

#include <msp430g2553.h>
volatile unsigned int i=0
void main(void)
{
        WDTCTL = WDTPW + WDTHOLD;
        P1OUT |= BIT0;
        P1OUT &= ~BIT6;
        P1DIR |= BIT0 | BIT6;
        while(1)
        {
                for(i=0;i<10000;i++);
                P1OUT ^= BIT0 | BIT6;
        }
}

If the build succeeds your tool-chain is ready. Next step is to flash the .elf to a device to see if it works.
