Hi All,
I've been using J-Link gdb server and commander with eclipse in windows for sometime, and decided to move in to Ubuntu 12.04 LTS. I have followed the exact instructions specified in read-me file, enclosed with the Linux software package. My problem is that the JLinkExe only works with sudo rights.
In other words,
If I execute it as a regular user,
samr@simpson:~/Downloads/JLink_Linux_V441g$ ./JLinkExe
SEGGER J-Link Commander V4.41g ('?' for help)
Compiled Jan 27 2012 19:11:22
Can not connect to J-Link via USB.

If I execute as sudo,

I'm a member in plugdev group as instructesamrd in readme, and "45-jlink.rules" provided with this J-Link software package
is in /etc/udev/rules.d/
Just wanted to know the point which I missed, to execute it as a regular user..
Any help would be kindly appreciated.
Kindly,
