Hi there,

I have a LPC55S69 EVK board and wanted to use the Jtrace to get the instruction trace. Since no trace pin is available on the board, I thought setting trace source to be "trace buffer" should work. Unfortunately, it is not allowed in OZone. I wonder if this is a hardware issue or software issue. More specifically, Is it because the hardware lacks the ETM/ETB support or the JLINK software hasn't supported it yet?

Thank you very much!

Currently, Ozone reported the following coresight components:

I suppose there at least should be an ETM module available, because the ETM module is advertised in the product manual.

Thank you Nino. You are really helpful.
