Detailed Features

As it is fully compatible with the Black Magic Probe, features are idebtical:
(following is a copy of Black Magic Probe's webpage)

• Targets ARM Cortex based microcontrollers.
• Connects to the target processor using the JTAG interface. Alternatively, the ARM Serial Wire Debug protocol may be used.
• Provides full debugging functionality, including: watchpoints, flash memory breakpoints, memory and register examination, flash memory programming, etc.
• Supports multiple targets on a single JTAG scan chain.
• Interface to the host computer is a standard USB CDC ACM device (virtual serial port), which does not require special drivers on Linux.
• Implements the GDB extended remote debugging protocol for seamless integration with the GNU debugger and other GNU development tools.
• Implements USB DFU class for easy firmware upgrade as updates become available.
• Works with Windows, Linux and Mac environments.

Allows you to:

• Load your application into the target Flash memory or RAM.
• Single step through your program.
• Run your program in real-time and halt on demand.
• Examine and modify CPU registers and memory.
• Obtain a call stack backtrace.
• Set up to 6 hardware assisted breakpoints.
• Set up to 4 hardware assisted read, write or access watchpoints.
• Set unlimited software breakpoints when executing your application from RAM.
