Скачать или смотреть How to change the BOOT_ORDER on a Raspberry Pi with a RPI HAT+ to boot from the NVMe SSD.

To change the BOOT order you can use either the "raspi-config" tool accessed from the command line. Additionally from the command line, you can make changes directly in the /boot/frimware/config.txt file. Or, you can use the friendly "Raspberry PI Imager" tool. (see below)

Remember to always update & upgrade first: ~$ sudo apt update && sudo apt full-upgrade

The Raspberry PI-5 is built with an exposed PCIe Gen. 2.0 (5GT/s) x1 ( with one lane for the user) FPC connector for users who want to add additional components such as the Raspberry PI AI HAT+ (hardware attached on top) or a third-party HAT or other similar add-ons. The PI HAT+ is available with a 13 TOPS or 26 TOPS Hailo-8 accelerator. The Hailo-8L (Entry-level) accelerator is integrated into the system using a M.2 connector (M.2 2242 form factor) with a M-Key format. On the other hand, the 26 TOPS is soldered directly onto the PI HAT+.

There are a few house-keeping chores (see below) you must make in order to use the PI HAT+ (and non-HAT's) via the PCIe connector.


By default the PCIe is not enabled unless connected to a HAT+ device.
To enable the PCIe add the following line:
dtparam=pciex1
( You can also use "dtparam=nvme" (nvme is an alias))
in the /boot/firmware/config.txt

To accomplish this task you want to use "sudo" and the "nano" editor as follows:

~$ sudo nano /boot/firmware/config.txt

To force Gen 3.0 speeds (8 to 10 GT/s) you can use the "raspi-config" GUI tool
or the command line. You only need to make changes with either one.

If you use the CLI (command line interface) do the following:
~$ sudo nano /boot/firmware/config.txt
Add this line: dtparam=pciex1_gen=3

If you use the "raspi-config":
Enter $ sudo raspi-config on the command line which opens a GUI: then select the following path:
Advanced Options
then, select "PCIe Speed"
then, "Yes"
then, "Finish" (to exit)
You must "reboot" for changes to take affect. ( ~$ sudo reboot)

To change the boot order from the PCIe: Use the "Raspberry Pi Imager" tool or the CLI.

Using the command line:
~$ sudo rpi-eeprom-config —edit

Replace the BOOT_ORDER line with: BOOT_ORDER=0xf416
(NOTE: To boot from a non-HAT+ device add the following line: PCIE_PROBE=1)

(Use a hash-sign (#) to comment out any line : will not execute the line.)

Using the Raspberry Pi Imager:
Within the "Operating System" window, click on the "OS" tab and scroll
down and open the "misc utility images" and
select and change your BOOT order.
