Another question: If I would like to debug several cards in parallel, do I need to change the port numbers (red numbers 2 to 4), to be unique?

Segger will normally prompt you to choose the device through the 'emulator selection' popup when starting a debug session (same as RTT). I wonder if it could be related to the '-nogui' option listed under 'other options' in your screenshot above?

Hi,

I found an answer to that problem myself, from studying SEGGERs documentation and comparing to the Debug Configration screen.

You can overcome this by problem adding the USB serial number of the device to the Debug Configuration screen. (Look at the red "1".)

I guess there is a way to find out the USB serial number of the device in a better way than mine: I started the JLink RTT Viewer with two devices connected and got the following popp where i was asked to choose between devices:

Hi, Vidar,

[Vidar]: Do you have several GDB server instances running in the background, ...

Ahem, ... I do not really know. I press the "Debug" button on Eclipse's top menu and choose one of the targets. When the Makefile has compiled and linked the program, I get this error message. I believe I only have one GDB server instance running, but I have not investigated what happens behind the scenes.

[Vidar]: and are you getting the Emulator selection dialog when starting the debug session?

I see no selection dialog.

regards, Elm
