5.3.2. Setting Core Configuration

To set the core configuration, follow these steps:

  1. Right click project directory (either HPS or Nios® V application) and select Debug > Debug Configurations.
  2. Select Ashling Heterogenous Multicore Debugging > cortex-a53-sum.elf.
  3. Under the Device tab, set these settings:
    • Debug probe: Agilex SI/SoC Dev Kit
    • JTAG/SWD frequency: 16 MHz
    • Transport type: JTAG
  4. Click the Auto-detect Scan Chain to list out all the available cores.
  5. Under Core Configuration, select Cortex-A53 and Nios V/m.

  6. Set the core specific configuration for each core under the Debugger tab.
  7. Specify the .elf file for each core under the Target Application tab. In this example, the target applications are added as nios-v-sum.elf for Nios V/m core and cortex-a53-sum.elf for Cortex-A53 core.
    Note: You can specify multiple .elf file for a single core.

  8. Set the breakpoint at a specific function under the Startup tab. This debug example uses the default settings.

  9. Based on the OS you use, configure the OS Awareness settings as follows:
    • Intel® HAL: No OS Awareness configuration is required.
    • Other OS: Under the OS Awareness tab, turn on Enable OS Aware Debugging, and select the OS as listed below:
      • µC/OS and Version: II
      • FreeRTOS and Version: 10.4.1
      • Zephyr and Version: 3.1.0

  10. Click Debug when all configuration is complete. All cores selected for debug are launched.

  12. In the Heterogenous Multicore Debug View pane, select Thread #1 [TAP 3 Core 0 (Cortex-A53)]. Pin one copy of the debug view to Arm processor using the Pin to Debug Context icon.

  13. In the Heterogenous Multicore Debug View pane, select Thread #1 [TAP 2 (Nios V/m Hart 0)]. Pin second copy of the debug view to Nios V processor using the Pin to Debug Context icon.
