I was having the same problem with a pcDuino-3-Nano.
The problem was solved adding a configuration option to the menuconfig
of u-boot: make menuconfig
"ARM Architecture" -> "Enable workarounds for booting old kernels"
then:
$ make CROSS_COMPILE=arm-linux-gnueabihf-
and then adding again the new u-boot-sunxi-with-spl.bin to the miniroot.
$ dd if=./u-boot-sunxi-with-spl.bin of=/dev/sdc bs=1024 seek=8
Now the OpenBSD kernel boots, but it get stuck loading when handling usb stuff:
