Raspberry Pi 5/4B not boot To update BootLoader EEPROM Tutorial

Introduction

The Raspberry Pi's EEPROM can store the firmware of the bootloader, ensuring that the correct firmware version can be loaded every time it starts.
All other models of Raspberry Pi computers use files located in the boot file system. bootcode.bin
The Raspberry Pi 4B's EEPROM can define functions, including manually updating the EEPROM configuration, modifying the bootloader, modifying the firmware release information, write protection, etc.

Steps

Use the Raspberry Pi Imager tool to update the EEPROM

You need to prepare a blank SD card

Select CHOOSE DEVICE to be burned

Here is an example of Raspberry Pi 5

Select the operating system, pull down and select Misc utility images

Select Bootloader (Pi 5 family)

.Select SD Card Boot or USB Boot or Network Boot

Click Next to burn the firmware

Phenomenon

Insert the Raspberry Pi, then start it and wait for at least 10 seconds.

The green LED light will flash in a steady pattern;

If you have connected a display, the HDMI display will be green when successful.

At this point, the BootLoader EEPROM has been successfully updated. Finally, turn off the power of the Raspberry Pi and remove the SD card. After inserting the SD card with the Raspbian system, the Raspberry Pi can correctly boot into the operating system
