My NanoPi R2S is never bootup.

I did following step.

*Using 64GB micro SD Card (Buffalo production)
*I installed disk images rk3328-sd-***,
but all of those images doesn't boot up.
*After inserting SD card, I connected type C USB power cable.
*small red sys light on NanoPi R2S turns 'ON' after connecting power,
but never blinking.
*I connected LAN cable to WAN port on nanopi r2s,
green and orange LED is blinking on WAN connector.
*Small WAN light on the same side of SD card never turns 'ON'.

I tried many time reading online instruction of nanopi r2s.
What can I do?

Thank you
