How to using LiveWatch function in XpressoIDE

[为何梁]

Just like this, when I run the program , it show me ''Target not available''(like pic1).Only when I pause the program can it show me the value(like pic2).And the play button is always unable to click(like pic3).What I use is FRDM-K64f ,but it doesn't work in both JLINK and P&E.

Thanks for answers

Best Regard

According to the IDE user guide, Live Variables are only supported with LinkServer debug - Link2 and CMSIS-DAP.
