ccsv3.3 abnormality

Marada Naveen Kumar

Hi,

    I am working with ccsv3.3 and dumped a code into the flash of F28335 containing some peripheral interrupts.Actually I disabled the ADC interrupt and dumped the code,but when i run it and kept a software breakpoint iam getting the break in the ADC Interrupt service routine.I disconnected the debugger and checked with a gpio toggling in the ISR,then i am not getting the interrupt.Can anyone explain this situation.

Regards,

Naveen.

    Naveen,

    I am not sure if I understand the issue correctly, but are you are saying that when you load the program using CCS 3.3 (on-chip flash programmer) the ADC interrupt is being getting hit even though it has been disabled. Whereas if you disconnect the debugger and check with gpio toggling you see the interrupt not being hit? Are you sure the correct program was rebuilt and reloaded to Flash while performing the debugging using CCS?

    Hi Aarti,

                  what you've conceived is exactly what i meant. I am sure that the program was rebuilt and i observed this phenomenon when i redumped several times.But the funny

    thing is it is working fine the other day.

    So is it working fine now, or it was working fine earlier but is no longer working? Issues such as this (where things work for a while and then stop working) are very difficult to answer or debug in a precise manner especially without having all the specifics and details as to all the variable and what all could have changed. The only thing I can recommend is for you to try to debug the code further to see why the ADC interrupt is not being disabled when it is expected to (check interrupt flags/registers etc when stepping through code).
