Xilinx SP605 manual 8System ACE CF Connections U1 Fpga Pin Schematic Net Name1, U17 XCCACETQ144I

Detailed Description

System ACE CF error and status LEDs indicate the operational state of the System ACE CF controller:

•A blinking red error LED indicates that no CompactFlash card is present

•A solid red error LED indicates an error condition during configuration

•A blinking green status LED indicates a configuration operation is ongoing

•A solid green status LED indicates a successful download

The mode SW1 setting is important because the System ACE CF can fail to configure the FPGA when the mode pins are set to the master modes (Table 1-30, page 55). A configuration failure from the master mode can drive INIT_B low, which blocks the System ACE CF from downloading a configuration ACE file. The FPGA mode pins must be set as specified in Table 1-30for the System ACE CF configuration solution.

With the mode switch SW1 set to 10 (Slave SelectMAP, Table 1-30), if a Compact Flash (CF) card is installed in the CF socket U37, the System ACE CF will attempt to load a bitstream from the CF card image address pointed to by the image select switch S1.

Every time a CompactFlash card is inserted into the System ACE CF socket, a configuration operation is initiated. Pressing the System ACE CF reset button reprograms the FPGA.

Note: System ACE CF configuration is enabled by way of DIP switch S1. See “17. Switches,” page 46 for more details.

The System ACE CF MPU port (Table 1-8) is connected to the FPGA. This connection allows the FPGA to use the System ACE CF controller to reconfigure the system or access the CompactFlash card as a generic FAT file system.
