Boot from NVME

VF2 Lite (EN）
1

The fastboot option makes it possible to create a bootable emmc, but is there also an option to boot from NVME? Or can I just copy the filesystem from SD-card to the NVME, remove te SD-card and then restart?

VisionFive 2 Lite / VisionFive support booting from NVMe, provided that your QSPI bootloader needs to support NVMe. Not required to remove SD card if your U-Boot bootcmd points to NVMe.

you can use this command to set the bootup sequence under the uboot.

setenv boot_devs “nvme mmc” 

saveenv

After you have connected once using a serial cable and saved the default environment to /dev/mtd1 using saveenv then you can update the variables stored in the QSPI flash from an OS:

$ cat /proc/mtd
dev:    size   erasesize  name
mtd0: 000f0000 00001000 "spl"
mtd1: 00010000 00001000 "uboot-env"
mtd2: 00f00000 00001000 "uboot"
$ sudo apt install libubootenv-tool
$ sudo cat > /etc/fw_env.config
# MTD device name       Device offset   Env. size       Flash sector size       Number of sectors
/dev/mtd1               0x0             0x10000         0x1000
^D
$

$ sudo fw_printenv bootcmd
$ sudo fw_printenv boot_targets
$ sudo fw_printenv boot_devs
$ sudo fw_printenv

But of course if you make a bad enough typo using fw_setenv you will need to use a USB to 3.3v TTL serial cable to fix up the variables in your Das U-Boot environment.

I have installed the nvme in the M.2 M key, but I see nothing in lsblk.

Is this the problem of the wrong QSPI bootloader? And how do I install the right one (in a visionfive 2 lite board)?

Make sure your USB power supply is providing enough power. I have two different power supplies, with the one, I can see (lspci) and use (hdparm/dd) the NVMe, with the other, I can see the drive (lspci) but can’t access it with some strange error (can’t remember, something about drive not having any actual storage capacity).

1、The power adapter is greater than 5V3A.
2、Replace the NVME with a different brand and model.
