<span class="tb_redtb_red_bold">WARNING:</span> <span class="tb_red">The Raspberry Pi 5 is not certified for Gen 3.0 speeds, and connections to PCIe devices at these speeds may be unstable.</span>
Then DON'T forgot to reboot
You also can refer to official documentatio:[https://www.raspberrypi.com/documentation/computers/raspberry-pi-5.html#enabling-pcie Enabling PCIe]
Use After reboot,use the lspci command to display your PCIe devices
sudo lspci
The output is as follows, note that the content of the third line depends on the NVME control you are using.
If a firmware update is available you will be prompted to install it and your Raspberry Pi will reboot. More information about updating the firmware on your Raspberry Pi is available in the [https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#bootloader_update_stable official documentation].
After updating the firmware and your SSD is still recognized, Please consider switching check [[#FAQ]] to a different brand or model know more detail and try again.
Then run the following command to check the BOOTLOADER version:
<pre>
pi@raspberrypi:~ $ vcgencmd bootloader_version
2024/0204/16 1518 09:2845:4100version 4c845bd37c8a7c7ff79173cdc50dd3facf63996f 86ccc427f35fdc604edc511881cdf579df945fb4 (release)timestamp 17080973211713429900update-time 17090851881713493735

'2024/0204/1618' is the firmware version;
==Flash OS onto NVME SSD==
The PCIe connection should work after a reboot, but your Pi won't try booting off an NVMe SSD yet. For that, you need to change the '''BOOT_ORDER''' in the Raspberry Pi's bootloader configuration:
* Use tool '''raspi-config''' to set boot order sudo raspi-configThen select '''6 Advanced Opitions''' => '''A4 Boot Order''' => '''B2 NVMe/USB Boot''' answer '''Yes''', then <code>sudo reboot</code>* Run the following command to edit the EEPROM on the Raspberry Pi 5set boot order.
sudo rpi-eeprom-config --edit
Then change the BOOT_ORDER line to the following:
