Detailed Features

Fully compatible with the Black Magic Probe, the features are identical:
(following is a copy of Black Magic Probe's webpage)

  • Aimed at ARM Cortex based microcontrollers.
  • Allows direct connection to the targeted processors JTAG interface. Alternatively, you may use the ARM Serial Wire Debug protocol as well.
  • Full debugging functionality is provided. This includes: watchpoints, flash memory breakpoints, memory and register examination, flash memory programming, etc.
  • Multiple targets on a single JTAG scan chain is supported.
  • Interface to the host computer is a standard USB CDC ACM device (a 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 upgrades (as updates become available).
  • Windows, Linux and Mac environments supported.

This board allows you to:

  • Load your application into the target processor Flash memory or RAM.
  • Single step through your program.
  • Run your program in real-time with 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.
