   Downloading and execution of LEON applications

   Built-in disassembler and trace buffer management

   Breakpoint and watchpoint management

  Command-line mode

   Remote connection to GNU debugger (GDB)

   Single word or burst access to AMBA on-chip bus

Advanced features

   Tcl interactive interpreter support

       All commands have been rewritten to support Tcl syntax

       TAB-completion on Tcl variables, procedures, namespaces etc.

       Tcl scripting:

           GRMON2 commands leave return values for scripting

           Variables are exported that let the user access DSU and debug drivers without using commands

           Start-up scripts

       Extend GRMON2:

           custom AMBA cores using new Tcl-driver interface

           easy custom command implementation using Tcl

           install custom handlers (hooks) on certain events

   In-application help system with full command reference

   Multi-core system support

   GDB does not consume the console, i.e. it's possible to inspect registers etc. while GDB is connected

   GDB watchpoint support

   Translates virtual addresses for GDB, e.g. it's possible to debug the Linux kernel

   Expanded register information listing
