Synchronize Multiple cores
Multiple cores are hardware-wise not synchronized by default after reset. Synchronization can be optionally enabled by winIDEA. The option is ON by default.
Open Hardware | CPU Options | Debugging. |
Make sure option Synchronize selected cores (stop/run) when possible is checked. |
Enable synchronization in Hardware | CPU Options | Cores | <Core> | Synchronize this core option. |
Make sure this option is configured for all cores you want to be a part of synchronization.
For suspending peripheral devices refer to this how-to guide.
