Green Hills Software's Multi debugger adds support for thread group breakpoints, along with a number of other new features. This comes in handy when dealing with multithreaded applications that interact with each other. The new run-mode JTAG debug support works with the ThreadX real-time operating system running on ARM7, ARM9, and ARM10 processors. The JTAG support works with the Green Hills Probe and Slingshot. These allow debugging while the processor continues to run.
