INIT LED
The dual-color INIT LED DS25 (callout 17,
status. During FPGA initialization the INIT LED illuminates RED. When FPGA
initialization has completed the LED illuminates GREEN.
System ACE SD Controller
The onboard System ACE SD controller U32 allows storage of multiple configuration files
on a Secure Digital (SD) card. These configuration files can be used to program the FPGA.
The SD card connects to the SD card connector J30 (callout 11,
below the System ACE SD controller on the back side of the board.
System ACE SD Controller Reset
Pressing the SASD RESET pushbutton SW7 (callout 13,
