Is it possible to use HW tracing from software?
Means enable trace and read the contents of the ETB from the code running on the same core.
Cheers
It is acutally on a Cortex-A9 (i.MX6Quad). I could read the trace registers with the debugger but currently have problems to activate the trace from software.I'll some more reading.
Thank you so far.
The trick was the OS_Lock Register.
