GRMON4
Status:
Development
The most recent version of our GRMON debug tool provides complete control over SPARC LEON and RISC-V NOEL processors with enhanced features like advanced breakpoints, GUI, and support for JTAG, Ethernet, and SpaceWire debug connections.
Overview
GRMON4 is a debug tool optimized for SPARC/LEON and RISC-V/NOEL-V systems, providing a non-intrusive debug environment. It enables embedded system developers to debug applications in a fast and efficient manner, improving productivity.
The target system can be monitored and controlled by the graphical user interface with scripting support. A large number of debug link interfaces are supported, and the debugger can be user-adapted for several system configurations
