MCUXpresso can't find JLink debugger

[jeffthompson]

I've just upgraded to MCUXpresso 11.1.1, and to Segger JLink 6.63e. Now, MCUXpresso can't find the JLink debugger. I get this message when I try to debug:

No compatible probes available. They may be disabled, disconnected, not powered, already in use or not compatible with this target.

I've tried uninstalling MCUXpresso (which, by the way, takes many hours to complete!) and re-installing, but I get the same result. I can run JLink from the command line with no problem, including connecting to my target hardware. Ican also use JFlash to erase flash and program program it. The program flashed this way does run correctly.

Here's what I get in the console window when I try to add a JLink debug configuration and then debug with it:

Hello,

Could you please let me know the J-Link debugger you are using on your side and the firmware used by the debugger? Is it really 6.63e? You mentioned this at first and I would like to confirm.

It's true that MCUXpresso 11.1.1 is compatible with version 6.62d.

Best regards,

Felipe

I’ve tried both 6.62d and 6.63e without success. I then went to the extreme of uninstalling both JLink and MCUXpresso, rebooting my PC, then re-installing MCUXpresso alone (which does, of course do its own installation of JLink 6.62d); again, this was unsuccessful.

Uninstalling MCUXpreso takes several hours; I have no idea why, but I don’t want to repeat this step if at all possible.

I’m now doing my debugging Segger Ozone 2.70e, which works just fine.

Hi Jeff,

Please check the below community document that explains how to Update SEGGER J-Link installation on MCUXpresso.

The description and screenshot are a little out-of-date, but I did find the setting, which pointed to the correct location. I’m still getting this error:

I also get this:

even though I select the server:

Which is why I’ve given up on the IDE for debugging and am now using Ozone. By the way, KDS 3.0.0 still works just fine.

The release notes for 11.1.1 say

• Upgraded to a later version of the SEGGER J-Link software (v6.62d)

so perhaps there is a compatibility issue with 6.63?

[jeffthompson]

Uninstalled both SEGGER JLink and MCUXpresso, then re-installed MCUXpresso. No difference. Here some additinoal debug information from the "Problem Ocurred" dialog box that opens when I try to debug:

Error in final launch sequence:

Error message from debugger back end:

I've also confirmed that SEGGER is installed in the correct folder. I think MCUXpresso actually finds and tries to run it, because I see the console window has this

If you look at the console log, it says it's 6.62d. nevertheless, I'll uninstall JLink and MCUXpresso, then reinstall MCUXpresso and try again.
