Basically, the board does not seem to detect the RTC.
Pin 1 (as marked on the board itself) on the rock64 is the same as pin 1 on the raspberry pi...
No, there is no config.txt because it isn't configured the same as the RPi, so a RPi guide will only get you so far. /boot/efi/extlinux/extlinux.conf will let you set any kernel boot time arguments that you need though. I believe you also need to actually enable I2C now via the dts overlays? Since as of 0.6.27 all devices (except SPDIF) exposed via the GPIO pins are disabled by default.
