Firmware Sectors

The NI motion controllers have the following firmware sectors:

68331 firmware sector—contains the software, including the real-time OS, required by the 68331 microprocessor
DSP firmware sector—contains the software needed by the DSP chip on the motion controller
FPGA1 firmware sector—contains the code needed to boot the FPGA that implements the encoder functionality on the motion controller
FPGA2 firmware sector—boots the FPGA that implements the digital I/O and RTSI functionality
