VSCode RTT connection to nRF54L15

[andrea@al2tech]

Hello,

I am developing a custom board based on the nRF54L15. 

Every time I do RTT connection from the extension i have been asked to prompt the target device (nRF54L15M33 in my case).

Is there a way to avoid it and set it as default into the workspace?

I have tried with the Command extension but it still asks the Target device. Here my command json:

"commands.commands": {

        "nrf-terminal.startTerminal": {

            "command": "nrf-terminal.startTerminal",

            "args": {

                "connectionType": "rtt",

                "device": "nRF54L15_M33",

                "memoryAddress": "auto"

            }

        }

    }

When I run it it prompts:

Any idea?

Thanks!

Hi Andrea, 

The J-Link prompt is likely coming from J-Link itself, not the nRF Connect extension. When J-Link doesn't recognize the device natively, it pops up its own dialog regardless of what the extension passes. The issue might be because the nRF54L15 is comparatively new to the JLink. If possible, I suggest using the URAT log to avoid prompts asking for the target.

Hi Amanda,

Thank you!

Unfortunately we do not have a UART port available for debug.

So you confirm this is not an issue only for us but all boards based on nRF54L15 will behave the same?

It seems strange to me because the nRF54L15_M3 is also listed on the JLink device list...like the nRF52 series...

Kind Regards,

Andrea

That's correct. Currently, J-Link cannot identify the device for nRF54L15, so you have to select the target manually.
