I got it to work with U-Boot 2022.04 from pkgsrc.

You can update U-Boot by installing the sysutils/u-boot-beagleboneblack
package on NetBSD 10 and the running "installboot -m evbarm -o
board=ti,am335x-bone-black NetBSD-HEAD-earmv7hf-202404241210Z-bone-
black.img". Note that's the uncompressed image file.

You can build the sysutils/u-boot-beagleboneblack package yourself, but
it does take a while because it needs to build its own GCC cross
compiler. I recommend just installing a NetBSD 10 binary package from
pkgsrc.org.

You can also use dd to patch the MLO and u-boot.img files into the
image, but U-Boot is much bigger than it used to be and so the block
counts given in the linked stackoverflow posting are wildly wrong. The
offsets appear to be correct though.
