Before proceeding please check which Linux (32 or 64 bits) you are using ($ uname -m) and install the according SEGGER J-Link package:

• x86 (release) or later (latest release)(Latest beta)
• x86_64 (release) or later (latest release)(Latest beta)

Once you have the latest J-Link installation open a terminal/console and check that your J-Link installation can be found under /opt/SEGGER/

$ anybody@ubuntu:/$ ls -l /opt/SEGGER/
total 4
lrwxrwxrwx 1 root root   23 Mar 27 09:39 JLink -> /opt/SEGGER/JLink_V645c
drwxr-xr-x 8 root root 4096 Mar 29 00:56 JLink_V645c

Assuming that you installed KDS under the default directory. Create a backup from the provided J-link tools from the IDE (in case you which to restore it later).

$ sudo mv /opt/Freescale/KDS_v3/segger /opt/Freescale/KDS_v3/segger_backup
$ sudo mkdir /opt/Freescale/KDS_v3/segger

Create a soft symlink to the latest SEGGER J-Link installation under KDS installation directory.

$ sudo ln -s /opt/SEGGER/JLink/* /opt/Freescale/KDS_v3/segger

Change/Create link for compatibility with new J-Link installation

$ sudo ln -s /opt/Freescale/KDS_v3/segger/JLinkGDBServerCLExe /opt/Freescale/KDS_v3/segger/JLinkGDBServerCL
