Opella-LD software debug support is provided via the open-source OpenOCD (http://openocd.org/doc/html/About.html) standard and provides fast code download to the target system with control and interrogation support for all core-processor and system resources including registers and memory. OpenOCD allows debugging via Ashling’s RiscFree™ Eclipsed based IDE and Debugger and the GNU GCC GDB debugger.
