The Xilinx Dynamic Function eXchange (DFX)
feature can change some blocks of PL function while keeping other areas of PL working,
allowing you to configure PL kernels on the fly. To use the DFX feature, when the
xclbin file is generated, configure it with your
host application. The new kernels in the xclbin take effect immediately without
requiring a reboot.
For platforms without DFX features, PL kernel must be packed into boot.bin. Copy it to the FAT32 partition on your SD card
and reboot the system. Then, configure the
with your host application.
xclbin file contains both bit files for PL kernel and metadata to
describe these kernel features and connections. Programming the
file on DFX platforms loads the bit file and metadata; programming on non-DFX platforms
only loads the metadata.
