I have been struggling with attempting debug with the Arduino Nano 33 BLE Sense with nRF5280 microcontroller via SWD with the use of the latest Arduino IDE 2.3.2. I have paid attention to the interconnection between the nano and an out-of-the-box Segger EDU mini debugger. While the debugger Commander and J-Link GDB Servers finds the nRF5240, the IDE fails to connect to the gdb server (The IDE cannot find "Arm -CMSIS-DAP). Have I missed something? Comments would be helpful. Thanks.
Hi @smacha. I'm going to ask you to post the full contents of the text shown in the IDE's "gdb-server" panel.
This procedure is not intended to solve the problem. The purpose is to gather more information.
Please do this:
- Attempt to start the debugger, just as you did before when you encountered the problem.
- Wait for the process to fail.
- Select the "gdb-server" tab in the panel at the bottom of the Arduino IDE window if it is not already selected.
- Right click on the panel at the bottom of the Arduino IDE window.
A context menu will open. - Select "Select All" from the context menu.
All the text in the panel will be selected. - Right click on the panel at the bottom of the Arduino IDE window.
- Select "Copy" from the context menu.
This will copy the selected text to the clipboard. - Open a forum reply here by clicking the "Reply" button.
- Click the
<CODE/>icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the debugger output is correctly formatted.
- Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the copied text into the code block. - Move the cursor outside of the code block markup before you add any additional text to your reply.
- Click the "Reply" button to post the output.

Please try this:

- Click the button on the toolbar near the top of the Arduino IDE window that looks like a play button with a bug on it ("Start Debugging").
Hopefully this time the debugger will start up and work as expected.
These are Debug and GDB console results switching programming device from ARM CMSIS-DAP to JLINK. Still no communication.

I experienced this error when I had the J-Link drivers provided by SEGGER installed. I was able to fix it by replacing those drivers with the WinUSB driver.
The only problem with doing this is that, if you are also using the J-Link software provided by SEGGER (e.g., "SEGGER J-Link GDB Server"), it only recognizes the J-Link when the SEGGER driver is installed. If that is a problem for you, let me know and I'll provide instructions for an alternative solution. Since this alternative solution is more complicated and inconvenient, I would recommend using the WinUSB driver solution unless you are using the SEGGER software currently. If you later find that you need to use the SEGGER software then you can always install their driver again.
I'll provide instructions you can follow to install the WinUSB driver:
- Download the "Zadig" driver installation tool from this website:
http://zadig.akeo.ie/ - Plug your USBasp into your computer.
- Start "Zadig".
- From the dropdown menu in the "Zadig" window, select "J-Link".
If it doesn't show up on the menu, then select Options > List all devices from the Zadig menus and check again. - Click the up or down arrows next to the Driver selection box on the right side until you see "WinUSB".
- Click the "Replace Driver" button.
- Wait for the driver replacement process to finish.
- Close the "Zadig" window.
Now click the "Start Debugging" button on the Arduino IDE toolbar again. Hopefully this time it will start up and work as expected.
Thanks. With the install of the WinUSB for J-Link, there is now GDB communication. Debug and GDB server consoles are shown below, where a breakpoint has been met. I now have to get use to working with Arduino debugging. Where does this solution lead Arduino and/or Segger regarding a more seamless resolution to the problem experienced?
