Debugger halts in dummy function :-(

saibhargavi — Wed, 09 Dec 2009 15:01:11 GMT

Hi,

I have written a piece of code using MQX where i scan the analog input samples every 125ms. I take total of ten samples and every one second i convert the sample monitored. When i run this code the debugger halts in some dummy function as shown the screen and it stays there for ever

Best Regards

It sounds like you have a spurious interrupt occuring. Usually, for debugging purposes most interrupt routines in the default vector table catch an unexpected interrupt and trap the thread of execution in a spin forever loop so that you can realize the bogus interrupt happened and you can look for it.

i've seen this too running the debugger, but in my case this happens because there aren't a ready task, for example: i was using two tasks but each one has a "big" delay and while the delay is happening MQX send the ProgrmaCounter to some DummyFunction written in asm. After the delay is happened returns to the first ready task.
