Hi, I compile my blink led program code (attached) for the msp430f5529 using mspgcc4 with option mmcu=msp430x5418. The result is that the led is blinking too fast. I thought it was that the delay was too short so I tried to change the delays in "for" loops, but it's still blinking too fast.
When removing the main loop ( while(1) ), the led is just flashing one time very shortly independently from the delay duration. Then a friend using mspgcc3 with the patch for msp430f5529 tried to compile my code and it works just fine. He also tried to use mmcu=msp430x5418 and the same problem appeared. Maybe using msp430x5418 instead of msp430f5529 makes some incompatible initialization ? For now I will use mspgcc3 with the 5529 patch.
