Rpi 5 NVMe boots only if USB-MSD is there #629
Comments
|
My guess is that there's something weird with your boot partition on the NVME drive. Why is it 4G in size? Are the cmdline.txt files the same on the USB disk and the NVME disk? I boot my Pi 5 from NVME all the time, so you've probably done something wrong. |
|
well, if i just download the img.xz and unpack it and use dd to write it to NVMe disk, then i get this 4G boot partition. I discovered that dd used 512 and the nvme 4096 blocksize. So then i looked with fdisk into the img-file and see a partition of 512M, and that makes sense because the bs = x8, so 4GB. so i did all by hand using parted/fdisk and mounted and copied all files. Then still i doesnt work, and used the rpi-imager: there the 4GB boot partition was there , no succes. Then used sd card copier, and eventually no succes, until i also used the SUB-MSB stick. And yes the content on NVMe is exact the same as USB. so also cmdline.txt. |
|
We don't support 4096 byte block size in the bootloader. That's the problem. |
|
Aha, okay then I go change the sector size to 512 and try to dd the img to nvmen1. Thanks for the hint! I'll let you know the result! |
|
It works! Thanks , i learned a lot having tried 'everything' and taking all kinds of directions, but finally it works and i understand why. |
|
One day we might fix this. It would be interesting to know if performance is noticeably better when the linux partition uses a 4096 byte block size. |
|
Actually, reopen. We should probably throw a more obvious error to stop people wasting their time with this in future? |
|
Well, I think this struggle appearing to be sector size other than 512 is very common for NVMe's If I just Google on this you see discussion about turning to a different block size in general. The NVMe card i have was from an old windows machine. I think , me as an hobbyist as many others re-use stuff and try to make it work, i don't know if you buy a new NVMe the default is 512 of something else. I thing even the rpi-imager uses dd as underlying method and i know this turns into weird partition table and filesystem not being mount-able. |
|
The M.2 HAT+ has documentation explaining it all, but not this exception of 4096 sector size which is not able to boot. |
|
Yeah, even I missed "nvme: error 10" in your screen grab which means NMVE_ERROR_UNSUPPORTED_BLOCK_SIZE |
|
The feature is on the todo list (but on the back burner) - to make this useful it will also require updates to RPi Imager / RPi OS for provisioning images in this format. |
|
I'm just suggesting making the error more obvious for now. |
google on nvme: error 10 yesterday didn't show up something, also i tried to see if the source code is somewhere. But is this something that can be found by me for instance, or is it something in the code nobody except the developers can find? |
Describe the bug
I am struggling with booting from an NVMe disk (Toshiba KBG40ZNS256G) and after a couple of mistakes and spending fun but also confusing hours i think i discoverd a bug or a symptom caused by doing something wrong or missing something , or it is a bug for real. Who knows? I'll try to explain:
I found out that simply using dd an image to a NVMen0 (4096 sector size) with bs=515(default) gives a weird situation. But the SD card copier tool helped to overcome.
Some info about my setup:
Raspberry Pi 5 Model B Rev 1.0
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
picture:
I've cloned USB-MSD into NVMe disk using the "SD card Copier" tool.
I changed the boot order,
BOOT_UART=1
POWER_OFF_ON_HALT=0
BOOT_ORDER=0xf461
NET_INSTALL_AT_POWER_ON=1
During power up SD card is not present, USB thumbdrive neither.
I would expect to boot from NVMe, since i changed the boot order:
.
What i get is a pi that doesnt boot and in the diagnotic screen:
picture:
nvme: error 10
But now the suprise:
But powering up with a USB-MSD in one of thew usb ports..., it boots from NVMe, it's so fast you could even not see any 'bios' screen or diagnostic screen.
I am happy my goal has been reached, but only to trick the pi with a USB-MSD first. after start up it is not mounted and i can just remove it.

└─nvme0n1p2 259:2 0 234.4G 0 part /
It's not the case a config.txt or cmdline.txt is read from USB-MSD, because it requires then to do something with UUID or correct devices (eg sda / sdb)
The last thing i want now is to get rid of the USB-MSD to be injected as a prerequisit to boot the NVMe ... or its a bug may be?
Steps to reproduce the behaviour
NVMe disk partitioned and having OS installed.
power up without SD ; but with USB-MSD : it boot from NVMe disk
power up without SD ; and NO USB-MSD : nvme error 10, boot fails and others (SD, USB ) are try out.
