Hello,
I'm trying to debug Contiki OS on a CC2538DK using eclipse as IDE and J-Link GDB. I use JTAG and not the XDS100v3 debugger because later we will use our own CC2538 board. Therefore I created a new debug configuration of type GDB SEGGER J-Link Debugging. The problem is that the debugging doesn't work. The GDB server is started and the application downloaded but then the GDB server closes the connection.
See the output of the JLinkGDBServer here:

When I check the box "Connect to running target" in the debugger configuration I additionally get these gdb error information:

Does anyone know what the problem here is?
