You need at least Segger J-Link driver version 8.10f or newer to get built-in support for nRF54L15. See www.segger.com/.../ReleaseNotes_JLink.html.

Hi Warren

Glad to hear you were able to figure it out. If it's any consolation, VS Code has grown on me since we moved from SES 🙂

Best regards,

Simon

I believe I had a complete install but had no luck in programming the nrf54l15.

I completely removed VC and all nrf tool chains and SDKs

then used Chocolatey to insure I had the support packages and up to date environments

then reinstalled VC and then the tool chain and SDK through VC and this has cleared the issue.

I can now program the DK with applications compiled in VC.

Jlink support is still to be added for the nRF54 chips so that their memory can be read and the RTT can be found automatically for debug support in VC.

Thanks, I miss Segger Embedded Studio

Then I assume you have the nRF Connect SDK and all its prerequisites installed on your computer as well. If so, can you try running an nrfutil device recover command from your command line tools to see if you can recover the nRF54L15 DK, since if the Programmer app doesn't work for programming the device either. It must be either that or that the correct versions of NCS prerequisites not being installed on your computer.

Best regards,

Simon

We are using the nRF Connect SDK with Zephyr.

The error is occuring while trying to program and debug an nRF54L15 chip through VSCode. Also worth noting that using the Nordic Programming application I am unable to read the memory of a nRF54L15.

Are you using SEGGER Embedded studios here or the just a J-Link viewer of some kind? SEGGER Embedded Studios does not support the nRF54 series, as we have moved to the nRF Connect SDK which is a Zephyr RTOS based SDK. Development is recommended to be done in VS Code with the nRF Connect extension, and building/flashing is done with west.
