Code Composer studio Debug functionality

Sonal Tanksale

We are using Code Composer Studio (Version: 5.1.0.09000) with bios versio 5.41.11.38.Compiler version - 6.02

In the debug mode we are able to set only one break point at once. When we try to set more, it throws an error saying that it is possible to set up more break points using currently availbale resources.Do we need to change any settings to be able to set one or more breakpoints?

Also in one of the PWM isr's we are facing the following problem -

The code stops at a breakpoint in ISR but never comes to the ISR routine again.

But if we do following procedure we are able to make it to come more times-

1. When the break point comes remove the breakpoint.

2.Set the break point again at same location.

This helped us to make it come to the ISR routine more than once.

Can you please help us understand this behaviour of hte debugger?

Hi Sonal,

.Do we need to change any settings to be able to set one or more breakpoints?

The setting (unchecking "Enable CIO function use") should allow you to set 2 hardware breakpoints.

for this error: C28xx: Breakpoint Manager: Error programming AET Job: This task cannot be accomplished with the existing AET resources.

Gautam

Thanks for the immediate help.

How do we tackel the other problme of interrrupts not coming again.

We have to remove and set the breakpoints manually everytime.

Hi,

The code stops at a breakpoint in ISR but never comes to the ISR routine again.

While debugging, please check the flag status in global registers. I guess, those are the ones who are stopping.

HI,

Is there any setting which would enable me to set more than 2 breakpoints.

It is tedious at times to live with only 2 breakpoints.

reagrds,

Sonal.

Hi Sonal,

The 28x devices have only 2 hardware breakpoints. By default, Code Composer Studio automatically sets two breakpoints for end of program and C I/O preventing you from having any breakpoints for debugging.
