I just tried on my own Orange Pi PC with current master (which will
become the final 2016.07 real soon now) and everything works fine.

wrt the flash process, nothing has changed simply dd
u-boot-sunxi-with-spl.bin to an offset of 8192 bytes on the sdcard.

Sometimes this happens if writing to the sdcard went wrong somehow,
sometimes the data can be unreadable or worse not readable reliably
for the board even though the PC reports everything as ok
(often when this happens the write takes longer then usual, indicating
  the PC has to retry it under the hood).

Often just repeating the dd fixes this (sad but true), I'm not aware
of any bug in rc3 wich would trigger this, and looking at the
commits in master since rc3 nothing stands out.

To double check I've just taken u-boot-sunxi-with-spl.bin for the
opi pc from:
http://koji.fedoraproject.org/koji/buildinfo?buildID=778437

And then did:

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8

And after that tested it, and it works fine for me, so it seems
that you indeed got unlucky by hitting a bad / weak flash sector
on the sdcard.

Regards,

Hans
