This tutorial
assumes you've already set up a Raspberry Pi with
Raspberry Pi OS with desktop
(Release date: July 4th 2024
System: 64-bit, bookworm). For help installing the Debian-based
OS on your Pi, check out the docs on
Raspberrypi.org.

1.0
To check
the kernel version, execute
the following command: |
| |
| pi@raspberrypi ~
$
uname -a |
|
|
| |
 |
| |
|
| |
1.1 Enabling
PCIe interface |
| |
First, enable the external PCIe port on the Raspberry Pi 5.
Edit /boot/firmware/config.txt and add the following at the bottom:
|
| |
| pi@raspberrypi ~
$
sudo nano /boot/firmware/config.txt
|
|
|
| |
# Enable the PCIe external connector
dtparam=pciex1
# Optionally, You can force it to Gen 3.0 (8GT/sec)
dtparam=pciex1_gen=3
WARNING
The Raspberry Pi 5 is not
certified for Gen 3.0 speeds, and connections to PCIe
devices at these speeds may be unstable. |
| |
Save and exit. In nano, you do that by hitting CTRL + X,
answering Y and hitting Enter when prompted. |
| |
|
| |
1.2 If powering via the on-board DC
jack, edit the EEPROM
configuration |
| |
| pi@raspberrypi ~
$
sudo rpi-eeprom-config -e
|
|
|
| |
|
| |
Add
PSU_MAX_CURRENT=5000 at the
end of the file that reads like this:
|
| |
 |
| |
|
| |
1.3 Reboot the
Raspberry Pi |
| |
| pi@raspberrypi ~
$
sudo reboot |
|
|
| |
|
| |
1.4 Use the lspci
command to display your PCIe devices |
| |
| pi@raspberrypi ~
$
sudo lspci |
|
|
| |
|
| |
|
| |
2.0 Build
the kernel and Apply patch |
| |
2.1 To get the kernel source, you
need Git. Begin by installing Git on your device, if you
don’t already have it: |
| |
| pi@raspberrypi ~
$
sudo apt install git |
|
|
| |
|
| |
2.2 Download the source code for the
latest Raspberry Pi kernel: |
| |
| pi@raspberrypi ~
$
git clone --depth=1 https://github.com/raspberrypi/linux |
|
|
| |
This can take
several minutes. |
| |
|
| |
2.3 Install the
build dependencies: |
| |
| pi@raspberrypi ~
$
sudo apt install bc bison flex libssl-dev make |
|
|
| |
|
| |
2.4
Download the patch |
| |
| pi@raspberrypi ~
$
wget https://suptronics.com/downloads/x1016.patch |
|
|
| |
|
| |
2.5 Move to the linux folder by entering: |
| |
| pi@raspberrypi ~
$
cd linux |
|
|
| |
|
| |
2.6
Apply the patch |
| |
| pi@raspberrypi ~
/linux $
git apply /home/pi/x1016.patch |
|
|
| |
If the x1016.patch is not download to /home/pi,
change the directory. |
| |
|
| |
2.7
Build configuration |
| |
pi@raspberrypi ~
$
KERNEL=kernel_2712
pi@raspberrypi ~
$
make bcm2712_defconfig |
|
|
| |
|
| |
2.8 Build the
kernel (64-bit). This step can take a long time, depending on your
Raspberry Pi model. |
| |
| pi@raspberrypi ~
/linux $
make -j6 Image.gz modules dtbs |
|
|
| |
|
| |
2.9 Install the kernel modules onto the boot media: |
| |
| pi@raspberrypi ~
/linux $
sudo make -j6 modules_install |
|
|
| |
|
| |
2.10 Run the
following commands to create a backup image of the current
kernel, install the fresh kernel image, overlays, README,
and unmount the partitions: |
| |
pi@raspberrypi ~
/linux $
sudo cp /boot/firmware/$KERNEL.img
/boot/firmware/$KERNEL-backup.img
pi@raspberrypi ~
/linux $ sudo cp
arch/arm64/boot/Image.gz /boot/firmware/$KERNEL.img
pi@raspberrypi ~
/linux $ sudo cp
arch/arm64/boot/dts/broadcom/*.dtb /boot/firmware/
pi@raspberrypi ~
/linux $ sudo cp
arch/arm64/boot/dts/overlays/*.dtb*
/boot/firmware/overlays/
pi@raspberrypi ~
/linux $ sudo cp
arch/arm64/boot/dts/overlays/README
/boot/firmware/overlays/ |
|
|
| |
|
| |
2.11 Finally, run
the following command to reboot your Raspberry Pi and run
your freshly-compiled kernel: |
| |
| pi@raspberrypi ~
/linux $
sudo reboot |
|
|
