5.2. Burn to SRAM#
Normally this mode is used to verify biststream.<\/p>\n\n\n\n
Because of its fast burning characteristics so the use of more, but of course the power will lose data, so if you want to power on the running program you can’t choose this mode.<\/p>\n\n\n\n
Click the function box below Operation to open the device configuration interface, then select the SRAM Mode option in Access Mode to set to download to SRAM, and finally click the three dots box below to select our generated .fs bitstream file . Generally speaking, bitstream firmware file is in the impl -> pnr directory.
