[Solved] RP4 eeprom update not working

[aus9]

Hi

I attempted to follow Juanito's excellent post at my own risk.

SNIP out some stuff

flashrom v1.2 on Linux 4.19.81-piCore-v7l (armv7l)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

# hmmm maybe it has to be flashed and rebooted sequentially?
sudo flashrom -p "linux_spi:dev=/dev/spidev0.0,spispeed=16000" -w "pieeprom-2020-06-15.bin"
same error
Any clues?

To be honest, the easiest way would be up just use a RasPiOS image, then run a full update.  it automatically does the updates.   I have a procedure that uses the normal RasPiOS methods, but I need to update my git repo to include the latest firmwares.

Your question about the bluetooth overlay, yes, that still works.  When the pi4 came out they dropped the pi3 from the overlay names, but kept them as aliases for backwards compatability.

dtoverlay=pi3-disable-bt  is the same as

dtoverlay=disable-bt

Thanks for the heads up. I will look at that soonish and will update when I know more. I have been watching some youtubers so was aware of Rasparian/RasPiOS and mention had been made noobs is supposed to automate the eeprom stuff.

Allegedly updates will allow usb booting and claims of a temp drop too.

Congrats on Admin promotion, well deserved.

I followed a tutorial for noobs/rasp*
It needed a file on the Debian system root edit to change setting from critical to stable.

Code: [Select]

tce-load -i rpi-vc
rpi-vc is already installed!
tc@rpi:~$ sudo vcgencmd bootloader_version
Jul 31 2020 14:43:39
version f8d1dc69144b10b4bd78b4b6d08658ac3005726d (release)
timestamp 1596203019
tc@rpi:~$ sudo rpi-eeprom/firmware/vl805
VL805 FW version: 000138a1
This step appears to be missing from the tutorial. And I can no longer tell if that was all that was stopping me.
There appear to be 2 text files that could rename critical but I am leaning towards just one.

I am so new at RPI I do not know if I am Arthur or Martha so I will let you decide if there is any merit in checking this allegation
And this suggestion is TIME BASED. At some point in time, updates that might be useful might reside in a diff  dir
rpi-eeprom-update-default

FIRMWARE_RELEASE_STATUS="stable"

Anyhow please mark as solved thanks
