Hi all,
I have been attempting to get the nRF Connect VS Code extension setup to try out some samples on the nRF9161-DK board.
I'm currently having a problem with a version mismatch between what the extension wants for nrfutil-device.exe and what the latest version of nrfutil installs.
Specifically the generated_nrfutil_batch.json file gets generated as follows:
{
"nrfutil_device_version": "2.15.2",
"family": "NRF91_FAMILY",
"operations": [
{
"core": "NRFDL_DEVICE_CORE_APPLICATION",
"operation": {
"chip_erase_mode": "ERASE_RANGES_TOUCHED_BY_FIRMWARE",
"firmware": {
"file": "C:\\nordic\\blinky_tutorial\\build\\merged.hex"
},
"type": "program",
"verify": "VERIFY_READ"
}
}
]
}
However when I run nrfutil install device using version 8.1.1 of nrfutil, it installs version 2.15.7:
nrfutil --version nrfutil 8.1.1 (b6089d0 2025-08-21) commit-hash: b6089d08a9cfdb292f8ab8d21e0908ded814cd11 commit-date: 2025-08-21 host: x86_64-pc-windows-msvc build-timestamp: 2025-08-21T14:12:43.593658000Z classification: nrf-external nrfutil search Command Installed Latest Status 91 0.5.0 Not installed ble-sniffer 0.17.1 Not installed completion 1.5.0 Not installed core 8.1.1 8.1.1 Installed device 2.15.7 2.15.7 Installed mcu-manager 0.8.0 Not installed npm 0.3.1 Not installed nrf5sdk-tools 1.1.0 1.1.0 Installed sdk-manager 1.9.4 Not installed suit 0.9.0 Not installed toolchain-manager 0.15.0 0.15.0 Installed trace
The effect of this is the Flash command fails within VS Code (toochain v3.2.1, SDK v3.2.1):
FATAL ERROR: command exited with status 1: nrfutil --json device x-execute-batch --batch-path 'C:\nordic\blinky_tutorial\build\blinky_tutorial\zephyr\generated_nrfutil_batch.json' --serial-number 1050 955061
If I run the same command from Windows Powershell I get more information stating that it is due to the version mismatch in the generated json file:
nrfutil --json device x-execute-batch --batch-path 'C:\nordic\blinky_tutorial\build\blinky_tutorial\zephyr\generated_nrfutil_batch.json' --serial-number 1050955061 Error: Unsupported batch file nrfutil device version: 2.15.2 - please regenerate your batch file with this version of nrfutil-device
I was able to temporarily work around this issue by manually editing the generated_nrfutil_batch.json file to be "nrfutil_device_version": "2.15.7".
Unfortunately this only works for flashing, when attempting to "Debug" the json file is autogenerated again and this gets reset to "2.15.2".
Another thing that was attempted was forcing nrfutil to install this older version, however this seemingly breaks nrfutil 8.1.1.
Also attempted to install nrfutil 7.7.0 as a co-worker had more success with that version, however it seems the Nordic URL paths have changed so I am unable to run the nrfutil install device command successfully.
Thanks any help would be appreciated with this issue.
