CoreCommander routines take control of key processor core (e.g. ARM, PPC, X-scale, Cortex etc.) functions using the built-in emulation/debug functions found in today’s RISC and DSP cores. They have been developed to speed-up board testing and debug by enabling kernel-centric testing.

CoreCommander offer two modes of operation:

Interactive – offering direct control of the core via a GUI or;

Python embedded* – where controls can be scripted into a complete program.

* requires JTAGLIve Script or JFT in ProVision

Benefits

• Overcomes deficiencies in boundary-scan registers
• Works with devices not compliant to IEEE std 1149.x
• Most popular processor cores supported (ARM PPC etc.)
• Code compatible with Python for test scripting
• Low-cost compared to other solutions.

Applications

• Supported by JTAG Technologies, JTAG Live and FTDI based controllers/interfaces
• Simple to use interactive GUI to perform core writes/reads
• Functions include ‘EnterDebug’, ‘ExitDebug’, ‘LoadMemory’, ‘SaveMemory’, ‘WritePC’, ‘ReadPC’
• Compatible with Python open-source scripting language.
• Works in tandem with JTAG Live Script – boundary-scan routines.

Specifications

• CoreCommander routines can be used to boost test coverage in applications that have only a small amount or even no IEEE std 1149.1 (conventional boundary-scan) test access options. By taking hold directly of the target processor’s core the user can write to or read from configuration registers and internal or external memory spaces.
