hi guy's, pay attention when looking for a emmc module for Renegade-cc, the socket is not the same as the one of Rock64 and OdroidXU4.
Here two links perhaps you haven't seen yet:

The ubuntu image provided by Libre/Firefly is crap, it misses a lot of kernel modules. I use Armbian now, they more-or-less support the ROK-RK3328-CC.
You can try the Armbian build I made, it's prepared for ipsec. https://www.dropbox.com/s/a2pqliuc2oyc7p3/Armbian_5.41_Roc-rk3328-cc_Ubuntu_xenial_default_4.4.120.img?dl=0
