Detailed Description

System ACE CF CompactFlash Image Select DIP Switch S1

System ACE CF CompactFlash (CF) image select DIP switch S1, switches 1–3, select which CF resident bitstream image is downloaded to the FPGA (Figure 1-26). S1 switches 1–3 offer eight binary addresses. When ON (High), the S1 switch 4 enables the System ACE CF controller to configure the FPGA from the CF card when a card is inserted or when the SYSACE RESET button is pressed. See “5. System ACE CF and CompactFlash Connector,” page 24 for more details about the System ACE controller.

Note: S1 switch 4 is the System ACE controller enable switch. When ON, this switch allows the System ACE to boot at power-on if it finds a CF card present. In order to boot from BPI Flash U4 or Xilinx Platform Flash (U27) without System ACE contention, S1 switch 4 must be OFF.
