Debug solution for ARM processors
14 October 2008
Macraigor Systems provides on-chip debug solutions for ARM Cortex-M3 processors.
Macraigor Systems LLC has ported its proprietary on-chip debug technology (OCDemon) to the ARM Cortex-M3 processors and is now offering full GNU toolsets to be used with these processors and Macraigor Systems interfaces.
Engineers developing applications for these new 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. In addition to support from several debuggers, Macraigor is offering a free port of the GNU toolkit (gcc, gas and gdb) for these processors on its website, (www.macraigor.com) as well as full support for Eclipse Ganymede.
Macraigor’s JTAG interface devices are immediately available for use with the ARM Cortex-M3 based cores as well as other ARM family devices including ARM 7, ARM 9, ARM 11, Freescale’s iMX series, XScale, and others.
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 rigours 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 comes into its own. 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 initialisation 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.
“Macraigor Systems is committed to providing hardware/software JTAG debug interface solutions for all current and future ARM technology-based processors,” said managing partner James MacGregor.
