[ABANDONED] Error: Could not find core in Coresight setup - J-Link Lite/TMPM369FDXBG

I've got a Toshiba BMSKTOPASM369BT551 dev kit with an TMPM369FDXBG ARM Cortex M3 MCU + a JLink Lite.

Before, I've managed to compile a simple blink app and even debug it in Ozone (I also have J-Link Plus)
Now, and I'm not aware of any changes to my hardware, I get the error below.

What does it mean? What might be broken and or anything I can try to fix it?

Thanks!
Matthias

Hello,

Thank you for your inquiry.
Such an issue is not known to us.
For reproduction we used a J-Link Plus, J-Link software V6.30b and eval board BMSKTOPASM369 v1.
Attached is the successful connect with J-Link Commander.

So everything is working as expected. You write you also have a J-Link Plus, could you try that one instead.
Does that work?

Best regards,
Nino
