[Discuss OpenCPI] ZynqMP ocpihdl load error

I am trying to load a ZynqMP FPGA image on a custom platform, and utilizing
the ocpihdl load command yields the following error:

  # ocpihdl load
~/opencpi/aarch64/artifacts/ocpi.assets.fsk_filerw_platform_base.hdl.0.platform.gz
  Exiting for problem: error loading device pl:0: Error loading fpga: No
such file or directory(2)
  # dmesg
  [ 289.802745] opencpi: open file(ffffffc074493c00) minor(0) initial
size(0)
  [ 293.361475] opencpi: fpga load request: addr: 0000007fa2341010 count:

  [ 293.369923] opencpi: load fpga node: ffffffc077fcd7f0, path: /pcap,

  [ 293.381403] opencpi: release file(ffffffc074493c00)
inode(ffffffc0744e1d00) minor(0)

I noticed the fpga manager is different from a previous Zynq platform, and
it seems to want to see a file in /lib/firmware to load instead of writing
the entire file into /dev/xdevcfg.

I also noticed that if I unzip the file, put it into /lib/firmware, and
echo the filename to /sys/class/fpga_manager/fpga0/firmware, it seems to
load just fine. At that point, the ocpihdl get command seems to hang the
platform.

At this point I am a little stuck. Anyone have current experience with
ZynqMP and the v1.7.0-beta.1 tag? Am I just too early on testing this?
Any insights would be appreciated.

Thanks,
Brian
