According to https://wiki.freebsd.org/FreeBSD/arm/Raspberry Pi

A FreeBSD bootable image for Raspberry Pi has both FAT and UFS partitions containing the following files:

  • FAT Partition
    • bootcode.bin - First stage boot
    • start.elf - Second stage boot
    • config.txt - configuration for start.elf
    • rpi.dtb - FDT file loaded via config.txt
    • uboot.bin - Third stage: U-Boot loader
    • uEnv.txt - configuration file for U-Boot
    • ubldr - Fourth stage: FreeBSD bootloader
  • UFS Partition
    • /boot/kernel - dynamic kernel
    • ... rest of FreeBSD ...
I'm running FreeBSD 12.0 and my FAT partition contains:-

There seems to be some discrepancy here. Does anyone know what's going on?

I'm particulary interested in what should be in uEnv.txt which I don't have.
 
Maybe for you... but what is supposed to be in it? It is used by other u-Boot environments such as the one I'm using.
