The LPC bus is emulated with an ARM -Cortex-M microcontroller, and does not run at the standard 33MHz clock. Although -the clock contains significant jitter, the connected chips respond and -communicate as expected. - -Details: -http://en.wikipedia.org/wiki/Low_Pin_Count -http://www.intel.com/design/chipsets/industry/25128901.pdf - - -Hardware Setup --------------- - -A VultureProg daughterboard was attached to a TI Stellaris Launcphad board. A -SST49LF080A flash chip was installed in the PLCC socket. The core clock of the -CPU was reduced from 80MHz to 16MHz to permit the logic analyzer to capture all -details of the waveform. - -Hardware: http://github.com/mrnuke/vultureprog-hardware -Firmware + SW: http://git.qiprog.org/ - -The logic analyzer used was a MCU123 USBee AX Pro clone. It was connected to the -"LPC probe" header of the VultureProg daughterboard.
