High-performance Ashling JTAG debug probe

Opella-XD is Ashling’s high-performance JTAG debug probe for embedded development on devices based on the RISC-V open Instruction Set Architecture.

The Opella-XD hardware debug probe is part of a range of tools provided by Ashling for development on RISC-V including IDE, compiler, simulator and debugger. It integrates with Ashling’s RiscFree IDE and Debugger under Windows and Linux.

Opella-XD Highlights

  • 3MB/s download speeds making it suitable for large, complex, software-intensive projects
  • Fine-grained adjustment of JTAG clock frequency from 1kHz to 100MHz
  • Auto-conditioning ensures maximum possible download speed with fastest JTAG clock frequencies
  • Hot-plug support – allows connection to a running target without resetting or halting
  • Opella-XD supports Multi-core debug for devices containing multiple RISC-V cores

Opella-XD Features

  • Supports 32-bit and 64-bit RISC-V devices
