Green Hills Software Delivers World's Most Powerful Embedded Linux C/C++ Debugger

Build Next-Generation IoT Designs Faster and Cheaper
MULTI for Linux

SANTA BARBARA, CA — December 11, 2014 — Green Hills Software, the largest independent software vendor for the Internet of Things (IoT), today announced a new MULTI® software development environment for embedded Linux developers. MULTI for Linux leapfrogs all other solutions in the market.

Until now, the state of the art for debugging Linux was a sad combination of print statements, command-line tools, and rudimentary graphical debuggers that are difficult to learn, setup, and use and lack the powerful control and visibility that modern electronic systems demand. This lack of high quality development tools presents a tremendous time-to-market and product robustness barrier to IoT designers, both seasoned and new.

Green Hills Software's MULTI enables developers to seamlessly control and debug all aspects of an embedded Linux system, including the Linux kernel, kernel threads, user mode threads and processes, and interrupt service routines (ISRs), all from a single tool. Developers can simultaneously interact with these entities in a single window or in separate windows per instance. MULTI enables developers to quickly master the most difficult device development challenges, including kernel panics, execution and data flows between user processes and the kernel, early hardware bring-up, device drivers, and performance analysis and tuning.

"The Internet of Things presents challenges and opportunities that demand powerful, flexible, scalable, cost-effective development platforms," commented Nathan Field, MULTI manager, Green Hills Software. "Linux developers will be amazed at how MULTI makes their everyday software development tasks easier, faster, and even fun."

Key capabilities of Green Hills Software's Linux debugging and development suite include:

  • Support for all modern embedded Linux versions, regardless of download source or Linux support vendor, and including Android distributions
  • Leverages the Green Hills Probe JTAG device for "stop-mode" debugging of kernel, ISRs, and user mode applications
  • Leverages I/O peripheral connections for "run-mode" debugging of applications, where the CPU is never halted
  • Fully multicore/SMP aware
  • Advanced visualization and manipulation of Linux kernel data structures, including shared memory regions, semaphores, and message queues
  • Advanced run control features available in stop-mode and run-mode enable seamless debugging of newly created threads and processes, zero-overhead breakpoints to enable visibility without intrusiveness, and the ability to debug system calls based on specific calling threads
  • Full visibility into application adjuncts, including shared objects and libraries, loadable kernel modules, and other intercommunicating applications
  • Powerful software browsing, editing, and exploration capabilities
  • Support for GNU GCC C/C++ compilers with optional support for Green Hills C/C++ compilers

MULTI for Linux is available today for ARM and Power Architecture, with other CPU architectures available upon request.
