• Connections are only allowed to single-core simulations, not to multiprocessor or multicluster simulations.
• No tracepoint support.
• No parameter support.
• Memory view only shows the current memory space.
• Disassembly only uses the current instruction set.
• Breakpoints can only be set on the current memory space.

Issues

You cannot use GDB when debugging software that uses semihosting. When a program tries to use semihosting with the GDB plug-in, the GDB debugger wrongly reports having hit a breakpoint:

Program received signal SIGTRAP, Trace/breakpoint trap.

When using the GDBRemoteConnection plug-in, start the simulation with the -D (or -S) flag. You cannot attach the GDBRemoteConnection plug-in to running simulations. It can cause segmentation faults on the simulation and the GDB client.
