Hi, I have an MSP430 and set the watchdog timer, however, when I cut power off and return power, sometimes it'll reset, and sometimes it won't. If I check with my debugger where it's getting stuck, it's just between two lines that say something like e30 BITB.B #4, 0X0028 e34 jnz 0Xe30 and it will loop forever there, however this will only happen part of the time, other times it'll work perfectly well, is there anyway to debug the watchdog timer, or is there something I'm doing wrong? I'd appreciate any help, Thanks

Just one more thing the problem seems to be exactly when I'm enabling my other interruptions, there is an instruction POP.W R11 however this will make it jump to a random instruction, however if I follow it step by step, it will jump to the interrupt instruction and then it'll work fine. However if I don't debug it it will never reset back to normal. ddshore@gmail.com wrote:> ddshore@gmail.com wrote: > > Hi, > > > > I have an MSP430 and set the watchdog timer, however, when I cut power > > off and return power, sometimes it'll reset, and sometimes it won't. > > If I check with my debugger where it's getting stuck, it's just between > > two lines that say something like > > e30 BITB.B #4, 0X0028 > > e34 jnz 0Xe30 > > and it will loop forever there, > > > > however this will only happen part of the time, other times it'll work > > perfectly well, is there anyway to debug the watchdog timer, or is > > there something I'm doing wrong? > > > > I'd appreciate any help, > > > > Thanks > > I've checked my interrupt flag for the watchdog and it's turned off > whenever this happens, however I've scanned through my whole code and > there's not one line in which I turn off the watchdog timer

No, I'm using the 149, there's no BOR in it.
