MCUXpresso J-Link encountered a problem for LPC865

uzza9 — Tue, 12 Dec 2023 18:08:14 GMT

Hello NXP Community,

I have a problem to run MCUXpresso with J-Link for my target board with LPC865.
Error message tells that "JLink Debug has encountered a problem".
As I looked into J-Link Debug Settings, it does not seem that JLink Debugger Settings of MCUXpresso has appropriate device.
I have set "Cortex-M0+" as device type in my JLink Debug SettingsFile.jlink because target device settings list of SEGGER J-Link V7.88 has it , but no LPC865 (or representative), however that does not work.

For your better understanding my case;
1. MCUXpresso version: v11.8.0
2. J-Link version: v7.88m (2023-07-19)
3. MCU: LPC865M201
4. attached you will see screen capture of;
a. JLink Debugger settings
b. target device settings list of SEGGER J-Link V7.88
c. JLink Debug SettingsFile.jlink

Please let me know how to get the appropriate device of LPC865 for MCUXpresso with J-Link.

Thank you in advance.

Hi,

I suppose that you use LPCXpresso860-Max board and MCUXPresso tools.

In the case, you can connect the J4 usb connector to PC,then delete the *Debug.launch file, which can be generated automatically.

Then click "Debug", the MCUXPresso tools can detect the correct probe you connected, and download.

If you use your own board and true J-Link device from Segger, I am sorry.

If you use LPCXpresso860-Max board and J-Link device from Segger, you have to close JP1, connect the J-Link device to J7.

Hope it can help you

Hello XiangJun Rong,

Thank you for your clarification.

It sounds like I CAN NOT use the Segger J-link probe (I am trying to use J-Link Base) for my custom board with LPC865. My team developed the custom board by referring to LPCXpresso860-Max board.

For your information, I have been using P&E Multilink Universal probe for my custom board debugging without problem. However I am trying to use Segger J-Link probe so that I can do "attach to running target" option that does not seem to work with P&E Multilink probe.

My new question, is there a way to "attach to running target" (or similar) for the P&E probe?

By the way, I attached pop up error message of "Unable to find device LPC865" that I ran into while connecting the Segger probe to my custom board.

It will be appreciated if you provide me any technical tip to resolve this issue.

Thank you.

Hi,

Because the LPC86x is a newly released sub-family, it is possible that the J-Link device from Segger does not support it.

Pls ask Segger support

Hi XiangJun Rong,

I got clear and thank you for your clarification that saves my effort to struggle the J-Link to my target with LPC865.
