How to enable PCIe on Raspberry Pi 5

  • We assume that you are using Raspberry Pi OS (bookworm) 2024-03-15

Step 1

  • Enable PCIe function

Edit /boot/firmware/config.txt file and adding following parameter in to the file.

Config.txt file.png

Save it and then do remember reboot your Raspberry Pi to take effect.

Step 2

  • Check if the SSD drive has been recognized
sudo lspci 
sudo lsblk

Step 3

  • Partitioning

Please divide the partition according to actual needs. Here I simply divided a partition and formatted it into ext4. Please refer to the configuration method related to the fdisk command to operate.

sudo fdisk /dev/nvme0n1
> Enter > Enter 
> w
sudo partprobe /dev/nvme0n1
  • Formating
sudo mkfs.ext4 /dev/nvme0n1p1
  • Create mounting point and mount the partition to directory.
mkdir mynvme01
sudo mount -t ext4 /dev/nvme0n1p1 /home/pi/mynvme01 -v 
  • Grant access permission
sudo chown -R pi:pi /home/pi/mynvme01 
sudo chmod -R 775 /home/pi/mynvme01
  • Modify the /etc/fstab to enable automount function.
sudo nano /etc/fstab 


/dev/nvme0n1p1   /home/pi/mynvme01  ext4   defaults,noatime  0 0 

save it and execute:

sudo umount /dev/nvme0n1p1 
sudo mount -a
sudo systemctl daemon-reload
df -Th
