| ==How to enable PCIe function on Raspberry Pi 5?==
| |
| * To enable PCIe functionality on the Raspberry Pi 5, follow these steps:
| |
|
| |
| ===1. Enable the PCIe External Connector:===
| |
| By default, the PCIe connector on the Raspberry Pi 5 is not enabled. To enable it, you need to add a configuration parameter to the `config.txt` file located in the `/boot/firmware` directory. You can use either of these lines:
| |
| <pre>
| |
| dtparam=pciex1
| |
| </pre>
| |
| After adding the line, reboot your Raspberry Pi for the changes to take effect.
| |
|
| |
| ===2.Enable PCIe Gen 3.0 (Optional):===
| |
| The Raspberry Pi 5's PCIe connection is certified for Gen 2.0 speeds. However, if you want to attempt using Gen 3.0 speeds, add the following line to the `config.txt` file as well:
| |
| <pre>
| |
| dtparam=pciex1_gen=3
| |
| </pre>
| |
| Be aware that the Raspberry Pi 5 is not certified for Gen 3.0 speeds, and using this setting may result in instability .
| |
|
| |
| ===3.Booting from PCIe:===
| |
| If you intend to boot from a device connected via PCIe, such as an NVMe SSD, you will need to modify the boot order in the EEPROM. Use the following command to edit the EEPROM configuration:
| |
| <pre>
| |
| sudo apt update
| |
| sudo apt upgrade -y
| |
| sudo rpi-eeprom-config --edit
| |
| </pre>
| |
| Then, change the `BOOT_ORDER` line to include NVMe in the boot order:
| |
| <pre>
| |
| BOOT_ORDER=0xf416
| |
| </pre>
| |
| This setting will make the Raspberry Pi attempt to boot from an NVMe device connected to the PCIe port .
| |
| ===4. Kernel Compilation (Advanced):===
| |
| If you need to compile the kernel to add support for specific PCIe devices, you can follow the steps outlined in the Raspberry Pi documentation. This involves cloning the Raspberry Pi kernel repository, configuring the kernel with `make menuconfig`, and enabling the necessary modules for your devices .
| |
| Remember to always check the compatibility of the devices you intend to use with the Raspberry Pi 5's PCIe interface, as not all devices may be supported out of the box.

| ==How to light up identical LED? ==
| |
| To light up UID LED indicator on a Raspberry Pi 4B or 5, you'll make sure the GPIO Pin of the UID LED connected to.
| |
| <pre>
| |
| GPIO (General Purpose Input/Output) pins on the Raspberry Pi.
| |
| </pre>
| |
|
| |
| ===Steps===
| |
| * 1. Identify GPIO Pins: <font color=red>GPIO4</font><br>
| |
|
| |
| * 2. Power On:
| |
| Make sure your Raspberry Pi is powered off before connecting the LED. Once everything is connected, you can power on your Raspberry Pi.
| |
|
| |
| * 3. Software Setup:
| |
| You'll need to write a small program to turn the GPIO pin on and off to control the LED. You can use Python with the `gpiozero` library or `RPi.GPIO` library to control the GPIO pins.
| |
|
| |
| ===Example Python Code with gpiozero:===
| |
| <pre>
| |
| from gpiozero import LED
| |
| from time import sleep
| |
|
| |
|
| |
| led = LED('GPIO4')
| |
|
| |
| while True:
| |
| led.on()
| |
| sleep(1)
| |
| led.off()
| |
| sleep(1)
| |
| </pre>
| |
|
| |
| ===Example Python Code with RPi.GPIO:===
| |
| <pre>
| |
| import RPi.GPIO as GPIO
| |
| import time
| |
|
| |
| # Set the GPIO mode
| |
| GPIO.setmode(GPIO.BCM)
| |
|
| |
|
| |
| GPIO_PIN = 4
| |
|
| |
| # Set up the GPIO pin as an output channel
| |
| GPIO.setup(GPIO_PIN, GPIO.OUT)
| |
|
| |
| while True:
| |
| GPIO.output(GPIO_PIN, GPIO.HIGH) # Turn on the LED
| |
| time.sleep(1)
| |
| GPIO.output(GPIO_PIN, GPIO.LOW) # Turn off the LED
| |
| time.sleep(1)
| |
|
| |
| # Clean up the GPIO pins before exiting the program
| |
| GPIO.cleanup()
| |
| </pre>
| |
|
| |
| ===Safety Tips:===
| |
| * Be careful not to short any pins on the Raspberry Pi.
