[ABANDONED] JLink on Debian Jessie: Connecting to J-Link via USB...FAILED: Cannot connect to J-Link via USB

Hi all,

I have purchased a JLink / JTAG Emulator USB for flashing to embedded devices.
Unitl now, everything works fine on Windows 7.
But as we're mostly working on Linux, I planned to port my scripts to Linux.

The Host Linux is a Debian Jessie 8 (x64), and so I've downloaded the latest versions of JLink (6.16 and today 6.22).
But as I launch JLinkExe, I desperately get the message Connecting to J-Link via USB...FAILED: Cannot connect to J-Link via USB
I tried to install the i386 version and then the x86_64, I tried to change the USB ports, I checked the cables, I tried under "root" user and my own user...same error. ;(

So. I have no more idea.
Any help / suggestion would be highly appreciated.


Best Regards,

Hello Karim,

Thank you for your inquiry.
The described issue is not known to us.
How did you proceed when installing the J-Link software package on your Linux machine?
Did you follow the instructions in the ReadMe if you installed the software from the .tgz archive?
Are you running Linux in a VM or natively?

Best regards,
