The same7 is a reference example which can be used as a reference board board for tracing an Atmel SAME7.
We have attached the segger jtrace to the board and the example is running fine. Now we want change the example to our board which is an SAMD51. The problem is that the script file in which the function "OnTraceStart" is, is a compiled "pex" file. Look in the directory for the file "ATMEL_ATSAME70_TraceExample.pex"

This is not helpful because the project is intended to show the use and handling with a segger jtrace probe.
Please send us the decompiled version of this file that we can adapt the code to our board.

The reference you given to me reference the example:
wiki.segger.com/Tracing_on_Atmel_ATSAME54
This example shows ETB tracing. Nice but not that what I want. Read above I want ETM tracing with SAMD51 Cortex-M4. chip: atsamd51n20

I download this project too and in this project the jdebug calls the function BeforeTargetConnect and here it s also a pex file.

void BeforeTargetConnect (void) {
Project.SetJLinkScript("./ATMEL_ATSAME54_TraceETB.pex");
}

I think I know what I must do in the function BeforeTargetConnect. The function configures the trace clock and pins for ETM tracing. This must be done before the program starts.
As I said above it would be very helpful, if we have the code from this pex files as a pattern for apdaptation.

Tnx, but it doesn't work and it seems it is our special Main clk configuration. The trace probe brings the message Trace clock not provided.
I will create a ticket.
