SDK Debugging Expressions update problem

I use system debugger for my application.

However, every time I press an Update button in the expressions column, the SDK stops operation for time to update the values.

 

I generate three 50Hz sinewaves with the PWM implemented in the PL. When I press the update button or change something in the expressions, I receive this kind of noise (shown in the figure) which lasts untill all of the variables are updated. Is there any way to deal with this issue?

Hi @slayer0112 ,

You mention that the PWM is implemented in the PL but is somehow controlled/driven by the PS side? I mean, I would expect the debugger to interfere somehow with the processors but not really with the PL.

Regards

I'm assuming yuiu are using the AXI timer to create the PMW?

In my case, the duty cycle for the PWM in calculated in PS.

The carrier wave of pwm is generated in PL using simple up-down counter. However, the reference is generated in the PS, and passed through AXI-Lite to PL part.
