Download Bitstream
You can click the Programmer button to perform bitstream downloading.
1.
DE2 board uses USB-Blaster to download bitstream. We support both JTAG
mode and Active Serial Programming mode (AS mode). By default, the
switch is set to the position of RUN for JTAG mode so that the SOF bistream
file is downloaded directly to the FPGA chip. AS Mode, where POF
bitstream is downloaded directly to the Flash-based Serial Configuration
device, should be used only when the design is finalized or the design has
to be tested without a PC. Set the switch to PROG for AS mode. Note that
the switch position should be kept at RUN position for normal operation.
Perform the following steps:
