Performance/Execution Profiling Will Not Display Time Information

Hello all, I am using J-Trace for ETM tracing in Keil 5.24. The SoC I use is nrf52840 from Nordic semiconductor.

However, while instruction tracing and other functions are able to work, execution profiling and performance analyzer does not have timing information available, not even call counts are displaied.

I have enabled ETM tracing option in the debugger setting and set the core clock correctly for 64 MHz.

I have search through the Nordic help centre and found that a person having the same issue even for ULINKpro.

Anyone have any idea of what could be the cause?

As much as I would like to post a picture here but the forum doesn't seem to allow it.
