  • Forum Post: Re: MSP430F5438 false breakpoint hits while debugging

    Mark Kranz
    The single step problem has been around since the x grade release. The single stepping problem occurs when you have a timer system running and giving recurring interrupts. What you see is that when a breakpoint is hit you try to step from that point forward and it constantly jumps to various points in...

    Peter Johansen
    We have build our own C# programming software, but based on the TI scripts. We are using RxD and TxD as you normally do in RS232. It is important to start every new try by switching off power supply, otherwise the mass erase will fail in the second try. Are you waiting for the acknowledge from...

    emreboy
    After I insert breakpoints and reset the code and then run the code again the software does not hit the breakpoints. As a workaround I found out that if I remove and insert the breakpoints back this time the code stops at the breakpoints. But it's rather annoying. Has anyone of u ever faced such...

    Hari
    Thanks for the replay and I will get back to you when I do this. But I have another question, is this only for emulation or is it can be used for the end device too? In IAR can it be done by modifying the lnk430F5418.xcl file? This is the linker configuration file for 5418. I found another file name...

    Hari
    Thank you for your answer. So you are saying that the code size can be a maximum of 128KB, since the size of flash is 128KB. Suppose if I add a memory chip of 2MB, can the size be that much?? Although self programming is a good functionality. It can't happen unless we don't issued the...

  • Forum Post: TIMER_A PWM generation, changing TACCR (duty cycle) without synchronization

    Panu Tuominen
    An old design is using TIMER_A PWM (OUTMOD_7) to generate low-bandwidth analog signal. However, TACCR registers are not double-buffered, so because we are generating a variable-duty-cycle PWM signal, care must be taken when changing the duty cycle (TACCR value). The most suggestions to avoid occasional...
