You probably figured it out by now, but the discrepancy is likely due to differing
block sizes. barebox documentation has `dd bs=1024`, while the default is 512.
boot firmware is a single chunk with barebox, so no separate second stage bootloader

You can check out the commit adding the EVB or the Pine64 Quartz64:
8d14f8e898b4 ("arm: rockchip: add support for the quartz64 board")

Feel free to send patches for your board along the same lines. :)
