Sysview tracing both cores
Posted: Thu Dec 13, 2018 2:32 pm
Hello. I have problem with tracing both cores using sysview tracing tool. I can't even trace both cores with sysview_tracing example. Tracing only one core works fine. I had tried using both gdb and telnet with various parameters for start and stop commands, but unfortunately the result was the same.
That's what error says:
Versions of tools that I use:
esp-idf v3.3
openocd 2018-11-05
That's what error says:
Code: Select all
