[SOLVED] JLinkGDBSserver -device options list

v01d1 · Aug 8th 2017, 6:12am

Is there a flag for this app (running on Linux) to dump the list of all known devices to it?

The manual refers to the page : segger.com/downloads/supported-devices.php

but this doesn't mention which versions support which devices. I'm not necessarily using latest Segger tools

Hi,

you can use the command "expdevlist <path to output file>" in J-Link Commander (JLinkEXE on Linux) in order to create a text file of supported devices.

I'm not necessarily using latest Segger tools

May I ask why?
If there is any regression, we would be happy to know about it in order to be able to fix it.

Best regards,
Niklas

Thanks Niklas,
I tried now:
/opt/SEGGER/JLink/JLinkExe expdevlist /tmp/devlist.txt
OR
/opt/SEGGER/JLink/JLinkExe -expdevlist /tmp/devlist.txt

Both give

SEGGER J-Link Commander V6.12d (Compiled Dec 21 2016 17:01:58)
DLL version V6.12d, compiled Dec 21 2016 17:01:52

Unknown command line option expdevlist.

May I ask why? If there is any regression, we would be happy to know about it in order to be able to fix it.

I'm afraid things will break if I upgrade, since current seems working well.

Btw, I have tried upgrading to latest yesterday, and I immediately ran into problems: after installation (Linux , 64bit) each time I try to start Segger GDBServer, the JLink USB device gets kicked-out , disconnected by kernel. I see device disconnect in the kernel log.
No issues like that with my current version.

Ah ok,, figured that out: you have to start JLinkExe, and inside it's shell do ExpDevList command.

Thanks

Hi,

after installation (Linux , 64bit) each time I try to start Segger GDBServer, the JLink USB device gets kicked-out , disconnected by kernel. I see device disconnect in the kernel log.

Sorry to hear that.
Could you please provide us with further information regarding your setup?:

Which version of the J-Link software? V6.18?
Which Linux distribution?
Which J-Link package was used? x86 or x64? DEB, rpm or tar?

I see device disconnect in the kernel log.

Would it be possible for you to provide us with the kernel log?

Best regards,
Niklas

Hi Niklas,

I cannot reproduce this anymore, after I have ran first Segger command successfully with root's privileges.

I've noticed that the Firmware in my J-Link got upgraded, after I have installed & ran the new Segger package - Firmware: J-Link V10 compiled Jul 28 2017 08:59:01.
That must have happened with the new Segger tools install, as my J-Link is older than that.

It could be that after running as root segger command, the firmware got updated, and the issue went away.
