Multiple cores are hardware-wise not synchronized by default after reset.
Synchronization can be enabled by the winIDEA option Synchronize selected cores (stop/run) when possible in Hardware / CPU Options / Debugging. Additionally, the Synchronize this core option in Hardware / CPU Options / Cores / <core> must be checked for each core you want to synchronize.
All options mentioned above are enabled by default.
If synchronization of cores is either not needed or unwanted, you can disable it by unchecking the checkbox Synchronize selected cores (stop/run) when possible in Hardware / CPU Options / Debugging.
It is possible to exclude individual cores from synchronization by unchecking Synchronize this core option in Hardware / CPU Options / Cores / <core> .
Suspending of peripherals (e.g., timers) is by default disabled. It can be configured with an initialization script <MCU>_CommonInit.ini, which is distributed with winIDEA in the Examples directory.
