 I cannot reproduce this here. Either by creating an image on the
sdcard by hand (I usually only netboot my boards so the sdcard have
only u-boot and a fat partition so u-boot can save its env) or by
taking FreeBSD-13.0-RELEASE-arm-armv7-GENERICSD.img and adding
u-boot on it.
 This was tested on an orangepi-one board (so same SoC, Allwinner H3)
and on a BeagleBoneBlack.
 I suggest to try with a clean install from
FreeBSD-13.0-RELEASE-arm-armv7-GENERICSD.img just to be sure.

 This line doesn't looks good.
