Raspberry mounted PCIE

Hardware connection PCIE

1. Use the cable to connect the cable interface of the Raspberry Pi, as shown in the figure below
2. Connect the solid state drive to the PCIE and fix it on the board. After confirming that it is correct, power the Raspberry Pi 5, as shown in the figure Tips: Remember to connect the SD card that can boot into the system to the Raspberry Pi.

System mount (used as expansion space)

1. The PCIE interface is not enabled by default on Raspberry Pi 5. Select one of the statements in /boot/firmware/config.txt and add it to the last file:

​x
sudo nano /boot/firmware/config.txt
​
#Gen2 low speed mode
dtparam=pciex1
​
#Gen3 high speed mode
dtparam=pciex1_gen=3
​

As shown in the figure:

2. Then restart the Raspberry Pi

xxxxxxxxxx
sudo reboot

3. Enter the following command to detect PCIE

xxxxxxxxxx
lspci

As shown below, SM2263 is my SSD solid state, and the other PI5 is the RPI chip

4. Start mounting

xxxxxxxxxx
#Create a mount directory
sudo mkdir yahboomba
#Mount device
sudo mount /dev/nvme0n1p1 ./yahboomba
#Check disk status
df -h

Before mounting

Successfully mounted

Difference between Gen2 and Gen3 modes

• Gen2 mode:

SD card read speed:

nvme read speed:

• Gen3 mode:

SD card read speed:

nvme read speed:

Conclusion: The SD card slot is not affected by the mode, but the PCIE board is affected by the mode. The Gen3 mode is much faster than the Gen2 mode.

Use nvme solid state drive as system boot disk

1. Modify boot information, enter the following command

xxxxxxxxxx
sudo rpi-eeprom-config --edit

Modify BOOT_ORDER to: BOOT_ORDER=0xf416 Enable PCIE_PROBE: PCIE_PROBE=1 Then save, exit and reboot. As shown in the figure:

Note: If you find that you cannot modify after multiple modifications, please connect to the network before modifying (wait for the network to self-synchronize), or set the correct time before modifying the file.

The following figure is a screenshot of the successful modification:

2. Method of downloading the system from nvme Method 1: Enter the following command

xxxxxxxxxx
sudo apt update
sudo apt install rpi-imager

Then, by clicking on the image installation on the desktop, you can download the system to nvme

Specific operation method:

Method 2: Or use a solid-state box to burn a Raspberry Pi system to nvme.

3. Remove the SD card from the Raspberry Pi card slot, install PCIE on the Raspberry Pi 5, and then boot it.

As shown in the figure:

You can see that the boot disk of the Raspberry Pi 5 is nvme.

4. If you want to change back to SD card boot, you can directly remove PCIE and it will return to SD card boot.
