GRMON4

• Read/write access to all LEON and NOEL-V registers and memory
• Execution control with support for multiple CPUs and OS threads
• Built-in disassembler and trace buffer management
• Breakpoint and watchpoint management
• Command-line mode
• Remote connection to GNU debugger (GDB)
• IDE support via the GDB connection, see Software IDE
• Auto-probing and initialization of LEON or NOEL-V peripherals  and memory settings
• Error injection for fault-tolerant LEON processors
• Supported debug interfaces: USB, Ethernet, JTAG, UART and  SpaceWire
• Common Flash Interface (CFI) compatible Flash PROM  programming
• Tcl scripting support- All GRMON commands are Tcl commands
• Custom commands and device drivers can be implemented by the user
• Hooks for installing custom handlers executed on certain events
• Peripheral device register bits available as Tcl variables
• TAB-completion on Tcl variables, procedures, file names etc.
• In-application help for all commands
• Context-based virtual memory handling
• Translates virtual addresses for GDB, e.g. it's possible to debug  the VxWorks/Linux kernel
