j-ling debuging in MCUXpresso IDE v10.1.1_606

Hello,

I tried do run the j-link debugger with our customer board and the MCUXpresso IDE v10.1.1_606. Unfortunately I get always an error.
I use an j-link Ultra+ connect to the board with an J-Link 10-pin Needle Adapter (8.06.04).

The attached picture “J-Link, GDB Server error.PNG”, “J-Link, Launching error.PNG” and “J-Link, GDB Server error screenshot.PNG” are screen shoots of the error.
The attached file “detail J-Link, GDB Server error.txt” is the error log of j-link.

Do you have a hint for my?

best regards
Dominik Fallmann

Hello Dominik,

Thank you for your inquiry.
Are you trying to debug eval or custom hardware?
If eval which one?
Can you connect to the chip using the J-Link commander?

Hello,

From the screenshots the target voltage VTref is suspicously low.
Are you running the target device in some low power mode?
For this particular device 3.3 V are usually expected.
If you run it in low power mode keep in mind that some modes disable debug interfaces so J-Link can't access the device anymore.
We recommend driving the device at 3.3 V for debugging.

Best regards,
Nino

Hello Nino,

thank you for your effort.
I have found the fault, Pin3 have to connect to GND and at our customer hardware was the Pin3 not connected.
At the attachment “customer_hardware_Pin3.png” you can find a cut-out of tag-connect datasheet (http://www.tag-connect.com/Materials/TC2050-ARM2010.pdf) vs a cut-out from JTAG connector of our hardware.
best regards
Dominik
