    Which device are you using (MSP430, CortexM3/M4, C2000, ...)?

    If you are using MSP430, the definition of a timer interrupt is quite simple:

    #pragma vector=TIMERA1_VECTOR
    __interrupt void TimerA1_ISR (void)
    {
    // your code
    }

    You don't need to put a definition of the interrupt in an assembler startup file or similar. The compiler does this for you with the #pragma command (see above).

    The list of available vectors can be seen in the device specific include file.

    If this does not help, maybe you can post a code snippet explaining your problem?

    Best regards,

    Dear Govardhan,

    Is it possible to send me the startup_ccs.c/.s files?
    If you don't want to post it to the forum, you can email it to: K-Gossner@ti.com

    Is Timer1IntHandler declared as extern?

    Best regards,

    Kai
