Ashling's Opella-XD EJTAG Debug Probe is the fastest available debug probe for embedded development on MIPSTM RISC cores.

Benefits of Opella-XD to the embedded hardware developer:

  • Accelerates the entire embedded-hardware debug process: ultra-fast installation, code download and flash programming saves time at every code rebuild
  • Instantly autoconfigures to target system
  • Long-term investment: works with all popular target architectures and compilers
  • Helps with the most difficult debugging tasks: hardware bring-up, operating-system booting, post-mortem debugging
  • Future-proof: works with latest hardware-debug protocols, all popular host operating-systems
  • Compact, easy-to-install target probe cables support all popular debug interfaces

Opella-XD Probe Specification:

  • High-speed USB2.0 (480Mb/s) interface to host PC or Linux workstation
  • Target EJTAG clock rates up to 100MHz
  • Auto-conditioning for fast EJTAG clock frequencies
  • Sustained code download to target at over 3MB/s (using 100MHz EJTAG clock)
  • Supports all MIPSTM hardware-debug standards: EJTAG 4.10, 3.10, 2.6x, 2.5x, 2.0x and 1.5x
  • 14-way or 20-way IDC target EJTAG connectors
  • Configurable Target-Reset and Test-Port-Reset, under full user control
  • Fine-grained adjustment of JTAG clock frequency from 1KHz to 100MHz
  • Supports target operating voltages from 0.9V to 3.6V. Opella-XD detects and automatically configures for the appropriate target voltage
  • Supports RTCK adaptive clocking of debug data from target (EJTAG 4.10)
  • "Hot-plug" support; allows connection to a running target without resetting or halting
  • Fully powered by USB interface; no external power-supply needed
  • Support for all on-chip hardware breakpoints; unlimited number of software breakpoints
  • Big-endian and little-endian target architectures supported
  • Full support for MIPS16TM/MIPS16eTM code compression

 

Compiler Support:

All popular MIPSTM C/C++ compilers are supported including GNU GCC, Green Hills Software and WRS/Diab Data and all other ELF/DWARF compliant compilers. See the separate PF-MIPS-XD datasheet.

GDB-Server-MIPS:

Ashling's GDB-Server-MIPS software package allows Ashling's Target Debug Probes to be used with the GNU GDB open-source debugger. The Ashling GNU GDB Server is available for Windows and Linux (x86 based) hosts and supports GNU GDB and all Eclipse CDT based debuggers (e.g. MontaVista Devrocket).
