Using expression for changing and monitoring variables causes ISR to halt

Hi, I'm using ZYNQ zc702 (Zedboard) with Vivado SDK and now I'm designing a controller for the control of the power converter.

When I tried to control the converter, I found a problem that ISR doesn't work while changing and updating the variable on the expression window.

This problem is seriously critical to the system... It could make the converter destroying.

I think the same problem with these links,

Unfortunately, there is no clear solution.

is this problem an inherent problem of this processor? I don't agree with this.

Because, I didn't find and see this kind of problem when I used CCS, which is based on SDK and Eclipse, for DSP.

I think the watch expression window is a very useful tool, but it is very frustrating and disappointing that this tool is not available here.

 Please give us some solution
