Hi,

In the documentation page for installing nRF command line tools, you can read that before you install nrf command line tools on Linux, it is expected for Segger software to be installed in the default location, whiich is  /opt/SEGGER/JLink. Could you please confirm that Segger software is properly installed on your system and that it is located on the proper path?

Apart from zip file that you downloaded and used, in the command line tools downloads page you can also find 3 more files that you can use for downloading nrf command line tools on Linux.
Could you please try using .deb and .tar.gz files for the installation and share the results here?

Best regards,
Dejan

Thanks  for your answer!

I have check the Jlink has been installed,and I set the env path like:

export PATH=/opt/SEGGER/JLink_V750a:"$PATH"

Actually I have tried the deb file to install the problem is the same,it shows that the libc6 on my unbuntu is two low .

After I search the resources,I found the libc6 can't be upgraded.

So I downloaded the lower version 10_13_0,and successfully get the file structure the official doc gives.

But when I use the nrfjprog ,It throws another problem:

ERROR: nrfjprog DLL load failed. Try again. If it keeps failing, please
ERROR: reinstall nrfjprog.

I have searched the doc ,nrfjprog return codes 21 is the problem.

So could you please help me solve the problem?

Hi,

Which version of the Ubuntu Linux operating system do you use?

Which file with the version 10_13_0 have you downloaded? Have you also installed it?

Best regards,

Thanks for your answer!!

The version of my Ubuntu Linux operating system is 16.04.

Of course I install the the version 10_13_0.There is only one choice to download.

The link is below:

https://www.nordicsemi.com/-/media/Software-and-other-downloads/Desktop-software/nRF-command-line-tools/sw/Versions-10-x-x/10-13-0/nRF-Command-Line-Tools_10_13_0_Linux64.zip

When I use nrfjprog --version in the command line to see the version.I meet the problem mentioned.

ERROR: nrfjprog DLL load failed. Try again. If it keeps failing, please
ERROR: reinstall nrfjprog.

So could you tell me why the DLL load failed?

I am sure I have install the JLink and set path variable.

Hi,

There is an unresolved dependency on your system which prevents libc6 to load and this causes the failure.

The version of Ubuntu that you are using is rather old. The nRF Command Line Tools v10.15.4 is tested on Ubuntu Linux 20.04.
I would suggest that you upgrade your Ubuntu Linux OS to v20.04 and do clean installation of the nRF Command Line Tools.
