RiscFree is Ashling’s Integrated Development Environment (IDE) and Debugger for Arm based development. Features include:

  • IDE based on Eclipse with full source and project creation, editing, build and debug support.
  • Integrated GCC and/or LLVM compiler toolchains.
  • Project wizards, templates and examples.
  • Single-shot installer that installs and automatically configures all the component tools to work “out-of-the-box”.
  • Automatic source-code formatting, syntax colouring and function folding.
  • Works with Windows and Linux Hosts.
  • Ashling Hardware Debug and Trace Probe support is fully integrated into the Debugger allowing hardware-based debug and easy setup, capture and display of Trace and Profiling data.

  • Integrated Code Coverage support:

  • Hardware and software breakpoints and watchpoints.
  • ROM or RAM based debugging support (e.g. hardware breakpoints for flash-based support).
  • Fast in-target Flash programming.
  • QEMU ISA simulator debug support including support for debugging of custom instructions. QEMU is installed and integrated into RiscFree ready-to-run.
  • High-level Register Viewer (e.g. based on SoC CMSIS-SVD or IP-XACT databases).
  • Integrated RTOS (e.g. FreeRTOS) and OS (e.g. Linux) Debug support.
  • Heterogeneous and homogeneous debug support for multi-core SoCs sharing a single hardware (e.g. JTAG/cJTAG/Coresight SWD) debug interface.

  • Creation of customisable RiscFree user-interface “Views” (Windows) using Python scripts.
  • Fully scriptable debug interface using Python or GDB syntax.
  • Support for SoC wide breakpoints i.e., a single breakpoint can halt all cores in active debug launches.
  • Core dump debugging allows post-crash debugging and analysis using a core dump file.

  • RiscFree supports core-specific software breakpoints in shared code i.e., only halt if a specified core is running for common code shared between multiple cores.

  • RiscFree has a dedicated Global Variables view to browse and show global variables in the application (ELF).
