Does it show a heartbeat on the front LEDs? If not,try flashing the SD,again. First I wrote the image as downloaded on SD card (raw mode). That didn't work nor did Etcher give me a negative feedback.Using the windows tool Mini Tool@Partition Wizard you can see if there are several volumes on the sd card.If not,you're doing it wrong. Never had any issues with Allwinner,Broadcom,Rockchip... Also I noticed I have to connect the WAN port and not LAN. Else you won't get proper access via DHCP.
Which image did you use? On the Nanopi R5C wiki there's a downloadlink to a gdrive.
Waiting for a RPi4 since Dec'21. So I just ordered the Nanopi R5C (which arrived by today). But it looks like there is no ARMbian for it, right now. Might it be compatible with another ARMbian image? Maybe the one for Nanoopii R5S?
Bananarama got a reaction from gounthar in [CNX-Software] - NanoPi R5C mini router features two 2.5GbE ports, supports M.2 wireless modules
