From this commit in u-boot upstream, it sounds like Revision K cannot reliably boot from eMMC, and recent versions of the board have an SPI flash added for booting: https://git.denx.de/?p=u-boot.git;a=commit;h=58e9502e6d98976e2df8ee7d9d8e61ce9250ad7b If your board has SPI flash, you could install u-boot from experimental (currently 2019.07~rc1) and install to flash. It might also be possible to backport the changes to 2019.01, if they're not too invasive. But it sounds like the vendor worked around the issue by changing the hardware; there may be no workaround in software. live well, vagrant
