Radxa Cubie A7A PCIe Connector NVME Not working

Cubie Series A7A
14

Ok… after trying again and waiting for about 40 mins, it booted up. Nvme is detected.

radxa@radxa-cubie-a7a:~$ lsblk

But I try mounting it, it does not mount it. The mount command just gets stuck.

I checked the lscpi output, it does show the nvme, but the Lnksta gen1 speeds with one lane.

I rebooted it, and it again stuck at the same point as earlier. So I guess have to wait for another 40 mins. :neutral_face:
