Why only the cpu0 ete has been added ?
And why are the other components (TPDA, TPDM, STM, CTI...) missing ?
Neil
At present, only ete0 is used, and other components can be added later if need.
Hmm, ok so I added the other CPUs and I was able to trace on all cpus, so I was wondering why
at least those were not added because having only ete0 declared is quite useless.
