Intel® IXP42X Product Line of Network Processors and IXC1100 Control Plane Processor: Using CompactFlash Application Note
This application note describes the hardware interface to a CompactFlash (CF) card connected in "True IDE" mode to the Expansion Bus of Intel® IXP42X Product Line of Network Processors and IXC1100 Control Plane Processor, and presents a Linux* device driver with basic functions to access the CF card. The device driver initializes the Expansion Bus timing and control registers to set up the interface that allows reading/writing the CF card. A simple Linux application program is provided to test the device driver. This application note also briefly reviews the CF architecture, Expansion Bus architecture, and the platform used to test the device driver.
