Error: JLinkARM.dll not found

[rwyung]

Hi,

Tried to use nrfjprog to erase / program the nRF 51 DK, when running nrfjprog --version, it yields the error of "JLinkARM.dll not found. Please reinstall latest JLinkARM.dll"

Tried a few solutions on the forum on related topics, like editing the install path in the windows registry (HKEY_CURRENT_USER\Software\SEGGER\J-Link), uninstall and reinstall JLink, then followed by Keil MDK and Nordic SDK, but no help

How can I resolve this problem? I am using v498C, and the installed path is C:\Program Files (x86)\SEGGER\JLink_V498c

Thanks

Hi Rwyung,

You can try to reinstall the nRF commandline Tools.

If you try to flash the chip using KEIL, do you have any issue ? Same with nRFGo Studio ?

Also please download and install the latest Segger Jlink driver.

Keil always works, and it's using V.498C

Here's the update:

I uninstalled nRF go studio, and subsequently nRFtools, then did a reinstall, but did not install again the Jlink v.498 that came along as part of the installation

Instead, I downloaded and installed the latest JLink driver (V.510f) from the link above, and then it works! (windows registry) also reflected the correct install path.

Thanks for helping.

I think the link to the command line tools has changed.

The page with the tools on now seems to be
