I am using the EDBG chip on the SAME70 Explained development kit, and using latest Atmel studio.
The first thing of annoyance is that the EDBG firmware in the latest Studio, 3.1f, wasn't working for me. When I attempted to debug it would crash with an error saying something like it couldn't get the program counter.
So I downgraded to 3.19, which got me working again.
Now my real problem is that I cannot get Program Trace Counter working. The play button is not enabled. Does this feature work with EDBG? Does EDBG or the SAME70 not support MTB?
