Hello,
I’m learning embedded development with a J-Trace Pro and an STM32L552E-EV board. After downloading the trace demo project from the segger wiki, I try to debug it with Segger Embedded Studio and Ozone.
Here is the board information.
https://www.st.com/en/evaluation-tools/stm32l552e-ev.html
Here is the demo trace project wiki.
https://wiki.segger.com/Tracing_on_ST_STM32L552
The attach is how I connect J-Trace Pro with the board.
However, when click the debug button, the panel shows the error information:
Disabled output of control charactersJ-Link software found at:

Could you please help to figure out the problem?
Besides, when I try to config and use Jtrace pro with STM32CubeIDE, it also doesn't work. Could you please share a tutorial to config to use J-Trace/J-Link inside the STM32CubeIDE?
Thanks.
