H A Dsysfs-driver-misc-cp5005 Description: Version of the FPGA configuration bitstream as printable string.
14 bitstream on reset. Normal FPGA behavior and default is to keep
15 configuration bitstream and to only reset the configured logic.
18 configuration bitstream with a simple reboot. Otherwise it is
20 configuration bitstream.
23 1 = keep configuration bitstream on reset, default
24 0 = reload configuration bitstream on reset
