Error while trying to flash NRF54L15-DK

[Adam W]

Hello,

Im trying to flash my dev board but im keep getting following error:

Error: One or more batch tasks failed:
 * 1057707318: [Probe] Emulator error: Failed executing JLink command string 'SuppressGUI': Info: No parameter or invalid parameter(s) for enabling/suppressing the GUI given. Using 1 (suppress GUI) as default.
    (Generic)

FATAL ERROR: command exited with status 1: nrfutil --json device x-execute-batch --batch-path /home/ketirange/ncs/v2.9.0/nrf/samples/bluetooth/peripheral_lbs/build/generated_nrfutil_batch.json --serial-number 1057707318

I have Nordic SDK running in VSCode. OS is latest Ubuntu 24 LTS.

Thanks for help.

Hi,

Did you always get this error, or did it start after some point? Can you let us know which version you have of nrfutil and J-Link drivers by sharing the output of these two commands?

• nrfutil --version

• nrfutil device --version

Also, how exactly do you attempt to flash your dev board (which command if using the command line, or via which GUI tool and how)?

I have always got this error, im flashing using VScode plugin from NRF connect sdk.

Hi,

I see. I reproduce the same when using the same version of J-Link as you have installed, but it works again when I down-grade to 8.10f. I suggest you do the same, as the latest J-Link version is not yet supported

I have installed jlink 8.10f and now im able to flash without problems. Thank you for help!
