You can change the Raspberry PI Bootloader firmware release version.
#raspberrypi5 #raspberrypi4 #raspberrypiprojects
NOTE: Only the Raspberry Pi bootloader versions from 30de0ba5 ( released on 2024/01/5 and later are compatible with the PCIe NVMe HAT.
[ Look at the bottom of this description for a more Advanced approach using the terminal to select a different firmware version. Simple too. It's explained well for beginners too. ]
You should make sure that your Raspberry Pi firmware is up to date. It ensures that your device has the latest security fixes, bug fixes, and new features. It keeps your Raspberry Pi stable.
In this introductory video, I show you how the Bootloader EEPROM "update" tool - named the "rpi-eeprom" selects the firmware release .
The Raspberry PI 4 and Raspberry PI 5, by "default" , use the FIRMWARE_RELEASE of "default" that is automatically updated every time you perform a:
~$ sudo apt update && sudo apt full-upgrade
However, to flash the firmware update's to the EEPROM bootloader ROM, you must perform a reboot:
~$ sudo reboot.
There are 3 Release firmware streams that I will show you in the video. They are beta, latest and default. For the most part, many users will use the "default" bootloader version that is updated, if needed, every time you perform a update/upgrade with a reboot. If you wish to change the version I suggest using the "Rasp-Config" utility. In the toll drop down to (6) Advanced Options and select the version you would like. I go with the "latest" as it is stable and the maturity is good. Choices we have to make as makers.

ADVANCED APPROACH:
*************************
Another approach, a little more advanced for beginners (but you can do it), is to open the following (rpi-eeprom-update) file by writing this to the terminal:
$ sudo nano /etc/default/rpi-eeprom-update
You need to use "sudo" for advanced privileges and a lightweight text editor - nano - to open the file. ( Use your UP/DOWN and LEFT/RIGHT arrow keys to move the cursor where you want it. )
If you want to replace the Raspberry PI's "default" bootloader firmware with the "latest" firmware
release version, delete what is [ INSIDE THE DOUBLE QUOTES ] , then type the word - latest- ( without the double quotes ) - inside the double quotes.
It should look exactly like this: FIRMWARE_RELEASE_STATUS="latest"
Now, to write your changes to the file: (The commands are at the bottom of the editor)
Use a combination of keyboard keys: tap the Control- key AND the small letter "O" key.
The editor wil ask if you want to write the current filename: YES you do!
Tap your "Return" key. This will write your changes to the file.
To exit the editor: Use a combination keys again: tap the Control-key AND the "X" key.
Then check your work by entering the following in your terminal :
~$ sudo rpi-eeprom-update
