“The Internet of Things presents challenges and opportunities that demand powerful, flexible, scalable, cost-effective development platforms,” said Nathan Field, MULTI manager, Green Hills Software. “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.
He said with the new version of MULTI for Linux, developers can now 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.”
In addition to support for all modern embedded Linux versions, regardless of download source or Linux support vendor, and including Android distributions, key capabilities of Green Hills Software's Linux debugging and development suite include:
1) Probe JTAG device for “stop-mode” debugging of kernel, ISRs, and user mode applications
2) I/O peripheral connections for “run-mode” debugging of applications, where the CPU is never halted
3) full multicore/SMP aware operation
4) Advanced visualization and manipulation of Linux kernel data structures, including shared memory regions, semaphores, and message queues
5) 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
6) Full visibility into application adjuncts, including shared objects and libraries, loadable kernel modules, and other intercommunicating applications
7) 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.
