Watchdog Handling

  • The device has a watchdog IWDT.
  • The watchdog is fed during flash programming.

Multi-Core Support

Before proceeding with this article, please check out the generic article regarding Multi-Core debugging here.
The THA6 family comes with a Cortex-R52 primary core and up to three Cortex-R52 secondary cores.

In below, the debug related multi-core behavior of the J-Link is described for each core:

Device Specific Handling

Connect

  • Secure Debug:
    • Authentication levels EL1 and EL2 are supported.
    • Only the default password (all bytes set to 0xFF) is supported. If you need to unlock the device using a custom password, please contact us through our support ticket system.

Reset

  • The device uses custom reset:
    • Sets reset catch so that CPU is halted immediately after reset
    • Performs reset via EDPRCR register
    • Ensures that debug power domain and system power domain are powered up
    • Powers core if necessary
    • Enables debug mode if necessary
    • Clears reset catch

Halt Timer Configuration

  • The device supports halt timer configuration.
  • The following timers are halted simultaneously with the R52 cores (STM, IWDT, SAFEWDT, CPUWDTn, BASETIMERn).
