j-link issue if used with Nordic EK j-link OB

[cocoa]

I wish to inform Nordic about this issue with jlink OB used on EK boards when used in OS X environment.

J-link OB returns " Can not connect to J-Link via USB." and a CDC disabling is due to establish a connection.

But, if I use j-link Lite Cortex M there are no problems, the connection is ready without disabling CDC.

All firmwares are updated.

Not fatal but annoying .

Tried with 3 EK boards, 2 EK version V1.0, one version V2.2 and a Jlink LITE Cortex-M Rev. 8.1

Connect EK to USB, then launch, in terminal, jlinkexe command. It results in a message from J-Link Commander :

SEGGER J-Link Commander V4.80h ('?' for help)

Can not connect to J-Link via USB.

To connect properly CDC disable is needed (use Seggere CDCDisable.term)

Launch it.

Then reconnect EK board.

Run jlinkexe command.

Now connection is ok, found swd-dp, found Cortex-M0.

Enable CDC to return in previous situation.

Connect EK, ...no device found.

Connect J-LINK LITE, all OK.
