nRF5340 simultaneously debugging on application and network cores

[kpreiss]

Hi-

I am trying to debug the network and application cores simultaneously using the beacon sample application configured for RPC HOST on the nrf5340DK board.  My configuration is as follows:

- Windows 10

- VSCode with nrf Connect and Cortex-Debug Extensions installed

I have tried opening two instances of VSCode. In the first instance, I flash the app and network cores and debug the app core.  I stop app execution at the top of main().  Here's an image of the first app debug session....

In the second instance, I make the rpc_host build active and attempt to Debug but get some sort of trap error and the debug session aborts....

What do I have to do in order to debug both cores at the same time using the beacon-rpc_host sample?

Thanks!

Kurt

Hi,

Yes, I opened two VS Code windows and used one for the Beacon sample on the application core, and the other for the RPC Host sample on the network core.

Best regards,

can you try disconnecting from both debug sessions, then reconnecting?  I got it to work ONCE after starting vscode, erase and flashing, then debugging.  However, once I stop the debug sessions then try to restart, it doesn't work.....

I cannot even connect to the application core again.  I get the following error message when attempting to debug the app core after erasing and flashing....

Hi,

After my initial testing I see the same as you. It works once in a while, but most of the time I get error.

Debugging multi-core applications is not a feature of the VS Code extension yet, but I will add this as a feature request to the VS Code team.

In the meantime, debugging both cores can be achieved using a compound debug configuration as discussed here: https://github.com/Marus/cortex-debug/issues/404#issuecomment-888594384.

Best regards,
