I think you need to load a flat device tree blob when using libbsd.

I am using this blob at the moment ...

https://ftp.rtems.org/pub/rtems/people/chrisj/uboot/bbb/am335x-boneblack.dtb

FYI I have created a tool to create SD card images. The 5th example in the
documentation here:

https://docs.rtems.org/branches/master/user/tools/boot-image.html#examples

shows how to create an image with an FDT blob ...

 rtems-boot-image -o sd-card.img -b u-boot-beaglebone -s 32m \
   -k dhcpcd01.exe -d am335x-boneblack.dtb MLO u-boot.img
