Macraigor Systems Provides On-Chip Debug Solutions

Macraigor Systems LLC has ported their proprietary On-Chip Debug Technology (OCDemon) to the ARM Cortex-M3 processors and is now offering GNU toolsets to be used with these processors and Macraigor Systems interfaces.



Engineers developing applications for these processors can control and debug their hardware designs and application software without the use of other system resources such as UARTs, Ethernet channels, or parallel ports. Processors are becoming more sophisticated with higher bus speeds and integrated peripherals. Debugging via classic methods, such as In-Circuit Emulators and ROM monitors, does not hold up to the rigors of real-time system test and debug on these next-generation processors. As processors become more complex, on-chip debug resources have been added to aid hardware and software designers. The interface to these on-chip resources is where Macraigor Systems excels. Via a choice of communication channels, a host debugger communicates with a Macraigor Systems’ device and then to the target processor. Since there is no need for any resident code, this debug method is available for hardware initialization and debug as well as Flash EEPROM programming, kernel, driver, and application software debug. Macraigor Systems offers a host based application that allows programming of Flash EEPROM via the JTAG connection.
