Hi,

[quote user=""]I searched the error online and people hints at running J-Link Commander but theres no version compatible for linux[/quote]

Try "JLinkExe" from the terminal.

[quote user=""]I get this error code from Segger Embedded Studio :[/quote]

It tries to read the ID-code of the CPU, but cannot connect to the device. I assume ST Link requires a set voltage of 3V? Are you powering your board with this voltage?

Kind regards,
