Hi,
I installed the latest Marshmallow beta for the wetek hub. Dual booting from sd-card is supported (boot screen shows message and power button on remote can be used to switch boot device from "nand" to "sdcard") but does not work with booting kszaq's builds from sdcard. I tested both Jarvis and Krypton releases, and get
"error in mount_flash: mount_common: could not mount /dev/mmcblk0p1"
The wetek hub release from raybuntu boots fine, on the other hand.
