Hello,

we received this inquiry via our support system in parallel.

Here is the answer we provided via mail so if someone stumbles across this inquiry they can read the answer as well:

Embedded Studio itself does not have extensive support for multi-core debugging.
It is user responsibility to set up the target system to a working state, such as before the debug session is started or in a J-Link script file.
The basic setup would be to load the code for all cores, e.g. program the memory with J-Link Commander or through ES if accessible,
get the cores into running state, and then connect to the core to be debugged.
If a reset or all cores is required or the other cores need to be
restarted after debug start, this could be done in a J-Link script.

To make sure no information is lost between the different channels that we have been contacted through this thread will be closed now.

Best regards,
Nino
