using stm32cubeide to debug stm32f767,it can use swv to trace a variable?
this is the swv setting. but I click resume button,the swv data trace timeline graph don`t respone.
Here is my SWV usage on a F7 board. Sounds working like a charm.
Common pitfall is bad core clock frequency setting.
Then maybe you're trying to track an event which is too fast ? Please note SWO clock is not running same speed than core clock ...
