error importing ARM64 BSP using script

[dvescovi1]

I generated an ARM64 workspace using this IoT ADK add on kit.
like:

This looks like it created my ARM64 workspace correctly.
I then imported all packages using the "importpkg *"
This also seems to have worked fine.
I then tried to import my "built for ARM64" BSP and got the failure "Incorrect BSP arch. Found arm, expected arm64"
I am not sure this is an ADK import problem or the fact I used the "binexport.ps1" script from the github
https://github.com/raspberrypi/windows-drivers

That script seems to have a hard coded path at line 30:

$bindir = $RootDir + "build\bcm2836\ARM\$buildconfig\"

I changed the "ARM" to "ARM64" and was able to generate to RPi_BSP_Release.zip but it has problems importing

XHCI USB doesn't work on 17763 on Pi4, so I don't think that would be that useful.
If you are working on Pi3, I do have a semi-working script on my local machine...
