Lacks of informations and settings

I’m looking for informations on how to set various jumpers (M.2 slot power, NAND-NOR, etc.), how to enable RTC (I have inserted a CR1220 battery, but RTC does not appear), which disk type can I insert on the M.2 slot or on the mPCIe slot. I’m using the latest OpenWRT SNAPSHOT. Except those problems, all is working as espected…

Thank you.
