I'm trying to use a Segger J-Link with Eclipse and GDB to debug my userspace application on a SAM9G25. I'm having issues getting the initial connection to my board.
I have installed the JLink GDB package from Segger on my host machine under /opt/JLink. I start up /opt/JLink/JLinkGDBServer under a terminal and it finds my JTAG emulator. I launch a "Remote C/C++ Application" debug session for my application under Eclipse. When it tries to make the initial connection, I get the following error under the "Remote Shell" log:
Code:
sh: line 2: gdbserver: command not found
And then under the "gdb" log I get these errors:
Code:
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.
warning: RMT ERROR : failed to get remote thread list.
warning: RMT ERROR : failed to get remote thread list.
I've searched around for like cases and I'm at a loss. Anyone have success getting GDB running in this manner?
If it helps, here's also the output from the gdb traces log:
