Good day,
I've recently updated firmware of my J-link Pro to ver 6.88 from J-link Configurator V6.88, upgrade process passed without any problem but CCS rejected to connect to MCU and I got message (please see pic1).
I updated CC Studio from download.segger.com/J-Link/JLink_TI_CCS_plugin_unified with latest driver for JLINK, and could not connect to the target mcu as as well, with error message showed on pic. 3. I though that problem was in Segger Link settings (pic. 6), but all looks OK, I check all paths and files, all looks good, and made one more test and found that J-Link could connect to target mcu by J-Link Commander ( pics 5 and 6), so all hw is in working condition.

My question is : what else I can check or test for resolve such kind of problem ? Because do not want return back ti xds100 after work with j-link.

small update, I tried to use software package 6.88a with JLink, and got same story as above. I suppose that problem somewhere in around JLinksctipt file, because randomly got couple success connections with mcu, but what was reason, I can't explain, may be because MCU was in some spacial state after manipulation from JLink Commander
.
May be someone can advice how to make log of JLink activity when it busy with CCS debugging, because logging from from CCS does not work? It should give us idea what to do next.

I did not have such kind of problem before, all project setup process was quite simple and user friendly, but I could not "roll back" to some working stage , because on download.segger.com/J-Link/JLink_TI_CCS_plugin_unified is version 6.88.0 only.

Good day Alex,
I'm appreciate for prompt response.
Probably, my initial explanation was not clear enough and pictures made you confused.

But our story is quite simple :
1. We have been using JLink & CCS since for last 8 months , since got it from Element14.
2. Everything worked well for CCS with version below 10.0.x
3. The CCS was updated to latest version approx. 5-6 days before. The JLink drivers for CCS was updated to ver.6.88.0 as well.
4. After we had found unpleasant thing : JLink stop to recognize of MCU(TMS570LSxxxx) of our project. (as showed on pic.1).
5.Segger software pack 6.x (I do not remember exactly version ) was removed by Segger Remove.
6.Latest software pack from Segger (ver6.88) was installed.
7.The device JLINK FW was upgraded to 6.88 by JLink Commander and after mcu flashing & debugging of our project n CCS stop to work.(pic. segger_problem_3)
8.Our device hardware : mcu ,connections, cable was tested from JLink Commander, all worked correct ( pic 4, pic 5).
9.I tried Segger V6.88a software pack(drivers,FW for JLink), without any success.
10. Pic.6 shows new interface of target connection,was found fault with CCS JLink Log creating, therefore we could not trace what was wrong during programming the mcu.

Please feel free to ask any additional questions.

Hi Alex,
Thank you for prompt response.

Just small clarification:

>> So the fact that the message box shows a version != V6.88 indicates that your CCS installation is *not* using a V6.88 version of the J-Link software
Yes, pic. 1 I got when I made upgrade of CSS ver. 10.0.0.xxx to 10.1.1.0004.
And as soon as found that Segger stop support Mcu what I had using last 6 months I made decision to upgrade Segger J-link support for CSS as well.
and used CCS Install New Software option.Pls. see pic 6. it's point 3 of my story.

3a. The CSS suggested to upgrade firmware of JLInk, but I downloaded Segger link Software Pack and made upgrade by Commander or Configurator ( I don't remember).

>>Moreover, since you are using V6.44b in CCS (according to the screenshot in pic1) the error message makes sense
yes, it was in begin my way.

>>because if you look up the release notes, the ones for V6.44e (3 versions later) indicate that there was a bug that made CCS device names to not be recognized.
Actually, I did not know about any bugs it. before was ok.

>>Your CCS installation is *not* using V6.88, otherwise it would just work because the V6.44e fix would have been applied.
Ok, how I can check what is rev segger's plug in installed in my current CCS ?

Hi Alex,
Thank you for update, we'll wait.

Thank you, Matthias.
