the only mention of emmc i see in the log is for a [probably] scripted regulator check at 1.8v
[ 2.159549] vcc18_emmc: 1800 mV
[ 2.159851] rk808 1-0018: Looking up vcc6-supply from device tree
[ 2.159995] LDO_REG3: supplied by vcc_sys
[ 2.167316] vcc_sys: could not add device link regulator.10 err -2
so my take is the emmc was not installed, or if it was installed it is not recognized by the system for some reason. not sure, but it seems to not be powered? in any event, if it was installed and powered then it should have been recognized as a storage device and since it was not i'd say it's dead and you need to return it as faulty.
however an additional test would be to have a serial console running at the boot of the rock64 with emmc boot and have a console that has the ability to log the output of the console and then post that log.
as with any other issue it's best to wait for others to reply to see if they see anything else to troubleshoot with this issue so give it a couple days.
