System Navigator™ Probe
for AMD Geode™ GX and LX Processors
The System NavigatorTM probe is designed to support the special features and integrated peripherals of the AMD GeodeTM GX and Geode LX processors. To learn more about the Geode GX and Geode LX processors, go to this link: AMD Geode Solutions.
On-Chip Instrumentation (OCI®) extensions for software debug and system testing have been jointly developed with AMD and are integrated into the processor. These OCI features provide a powerful debug tool with advanced features at a competitive price.
The System Navigator probe is used for hardware testing and integration, BIOS development, and other firmware/software testing. In addition to hardware and software breakpoints, processor run control, and access to all CPU registers and coprocessor registers, the System Navigator has on-chip trace features. Trace information is decoded and displayed as executed instructions. Trace is captured in on-chip memory (128 x 64-bit frames). The trace window displays disassembled instructions interspersed with system messages such as interrupts and exceptions.
The System Navigator probe connects to the target system using a 14-pin debug connector and optional off-chip trace connector. The System Navigator runs on a Windows® 2000/XP PC or Linux PC over a USB 2.0 port or optional 10/100 Ethernet connection. The GNU-based source debugger program GDB is included, and provides the user with an easy-to-use source level interface in addition to the assembly level debug user interface.
