Design files available from the

To upload a design over the network into the user portion of flash memory on your
board, perform the following steps:

“Connecting to the Board Update Portal Web Page”
to access
the Board Update Portal web page.
2. In the Hardware File Name field specify the .flash file that you either downloaded

3. Click Upload.
4. To configure the FPGA with the new design after the flash memory upload process
is complete, press PGM_SEL (S10) until the POF 1 LED illuminates, and then press
LOAD (S11) to configure the user hardware portion of flash memory.
