Amlogic-no Discussion

I installed no-nightly on an SD card for a s905X2 box (g12a_s905x2_2g).
Coreelec works perfectly, but I can no longer boot with Android
The entry in the menu (Reboot from eMMC/NAND) is missing
I tried it with a second box (g12a_s905x2_4g_1gbit) and had the same problem
This works perfectly with X3, X4, 922 boxes
There is no problem with ng-nightly

When I try ceemmc -x I get the error message:

eMMC size: 0x00039d000000 [16GB]
Partition ‘/dev/reserved’ does not exist!
Failed to read original partition table!
