Raspberry Pi 4 EEPROM bootloader rescue image
|
|
*********************************************
|
|
|
|
The Raspberry Pi4 has a small EEPROM used to store the bootloader.
|
|
|
|
This rescue image reverts the bootloader EEPROM to factory default settings.
|
|
|
|
This rescue image also updates the USB 3.0 (VL805) firmware to the latest
|
|
version (138a1) with better full-speed Isochronous endpoint support.
|
|
|
|
To re-flash the EEPROM(s)
|
|
|
|
1. Unzip the contents of this zip file to a blank FAT formatted SD-SDCARD.
|
|
2. Power off the Raspberry Pi
|
|
3. Insert the sd-card.
|
|
4. Power on Raspberry Pi
|
|
5. Wait at least 10 seconds.
|
|
|
|
This easiest method for creating and formatting the SD-CARD is to use the
|
|
Raspberry Pi Imager from https://raspberrypi.org/downloads
|
|
|
|
If successful, the green LED light will blink rapidly (forever), otherwise
|
|
an error pattern will be displayed.
|
|
|
|
If a HDMI display is attached then screen will display green for success
|
|
or red if failure a failure occurs.
|
|
|
|
N.B. This image is not a bootloader it simply replaces the on-board bootloader.
