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 1-30
for 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.
