The live mode is supported.
Can you try to use the Celadon P, not O-MR1? Some patchs will only exist in P, not in O-MR1?
I've compiled the celadon image using the omr1 manifest. I trying to boot a device using N2930 CPU, in live mode, but the screen turns black right after selecting the boot entry and the device freeze. I understand this is not part of the officially tested platforms, but I'm willing to debug it (I used to compile Android-IA 7 and 8 and they were running fine on the same platform).
Is the live mode still supported and what can I try to at least get the device to start booting?
