Reterminal DM how to SSD boot?

[donserdal]

Describe the bug The documentation on the hardware guide is missing the instructions needed to boot from the NVMe Expansion. I have followed both:

https://hagensieker.com/2022/04/17/booting-a-raspberry-pi-cm4-from-an-nvme/ https://www.jeffgeerling.com/blog/2021/raspberry-pi-can-boot-nvme-ssds-now

But the reterminal keeps booting from the eMMC.

Hardware used:

• Reterminal DM
• SSD expansion board with Dual NIC (https://www.seeedstudio.com/reTerminal-DM-Dual-LAN-and-SSD-extension-p-5766.html?)
• Patriot 256GB NVMe M.2 SSD (P300P256GM28)

To Reproduce Steps to reproduce the behavior: Go to https://wiki.seeedstudio.com/reterminal-dm-hardware-guide/#install-ssd

Expected behavior Booting from NVME

Additional context Current bootloader settings:

user@reterminal:~ $ rpi-eeprom-config
[all]
BOOT_UART=0
WAKE_ON_GPIO=1
POWER_OFF_ON_HALT=0

# Boot Order Codes, from https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#BOOT_ORDER
BOOT_ORDER=0xf516

# Set to 0 to prevent bootloader updates from USB/Network boot
# For remote units EEPROM hardware write protection should be used.
ENABLE_SELF_UPDATE=1

user@reterminal:~ $ lsblk

Have you check the version of your bootloader? Here is the detail information.

Or you can have a try to format the emmc, and try to boot from ssd again~

Hi, I have tried to reproduce your eeprom boot order setup with the reTerminal DM and external NVMe M.2 SSD with the SSD expansion board with Dual NIC. I could boot into with SSD without any issue.

So I guess what you need to do is making sure the "root=PARTUUID=" in the /boot/cmdline.txt file is aligned with the UUID from the NVMe like shown below:

Please let us know how it goes.
