USB Flash drive booting from June 22,2023 RPI Snapshot FreeBSD 14.0

Hello and Happy 4th of July Holiday

I downloaded this June 22, 2023 version of the  RPI snapshot and burned 
to a USB flash drive to test on my Raspberry Pi 4B with 8 GB

Is there a recipe that some machine follow to build this image? Can I 
have that recipe to verify the build process?  What should I do about

the

It try to TFTP  boot an image,  I was not setup for yet.  I will google 
and find some docs and webpages to help me out.

EFI boot manager: Cannot load any image

Yes, I can take a working  bootaa64.efi file and replace this one 
version  Then see if I can boot my raspberry pi 4B.

What else do you suggest to do to check or verify.  My system was 
booting the older version of FreeBSD 14.0 from my

500GB SSD.  See my blogpost for details.  Yes, snapshots of 14.0-CURRENT 
can have problems, so I just wish to share my experience.

I am afraid I over looked some small simple detail that I did not change 
or setup.  My apology in advance.

I am interested to learn how to use this nice 2023.01 U-BOOT and learn 
to debug by PXE booting the Raspberry Pi.

Is there a  website tutorial about using U-BOOT>  to test and learn 
about your ARM64 Hardware?  RTFM manual

Anyone else encountering this particular issue from a snapshot image?
