i created the u-boot by

make odroid-c2_defconfig
make -j4

and generated a flashable file according to : doc/board/amlogic/odroid-c2.rst.
this is a little bit different as for the libreelec-cc board. The process doesn't
genarate a u-boot.bin.sd.bin file only a u-boot.gxbb file. This file i flashed according
to the instructions of odroid-c2.rst.

You mention "last emmc changes" what does that mean?

best regards
