NVME - on orange pi 3b

[Kishor Pise]

I have orange pi 3b, that has one NVME ssd. This boots hybrid from SD card and system is on NVME. I tried to make boot it without SSD but no luck as of now. my nvme is fast and supports 5GBS speed.

 

/dev/nvme0n1          /dev/ng0n1            AA250310076          FIKWOT FN955 2TB                         0x1          2.00  TB /   2.00  TB    512   B +  0 B   X0430P00

 

Its avg benchmark speed is 415mbps which is very slower than avg. 

 

 sudo lspci -vv | grep -i "LnkSta"

                LnkSta: Speed 5GT/s, Width x1
                LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete- EqualizationPhase1-
                LnkSta: Speed 5GT/s (downgraded), Width x1 (downgraded)
                LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete- EqualizationPhase1-

 

 

Not sure, if this is due to power management, or due to hybrid approach while booting or some problem with board itself. can some one help me ?

Are you trying to boot from spi with system on nvme? or trying to boot another system on a sd card?

direct boot from nvme isn't possible. Boot loader (u-boot to say) must be present on SPI, eMMC or microSD.
