Ubuntu 18.04.4 on RaspberryPI4 8GB boot issue

[malik.badereddine]

I'm running Ubuntu 18.04.4 on a RaspberryPI 4GB and it is a great experience, I get the new Raspbery PI4 8GB and naturally I tried to boot it from the same SD card that was on the 4 GB model, unfortunately I'm getting the following issue on the boot screen ( screenshot on the url )

can you please help me?

You'll need to update the firmware files and possibly the Kernel on Ubuntu 18.04.04 in order for this to boot on a Pi 4 8GB. The new power supply requires new firmware drivers and old firmware would simply crash which is why the bootloader checks for this will refuse to load incompatible firmware.

If rpi-update is supported on Ubuntu then that might be the easiest method

This advice from an employee of Canonical seems directly relevant to getting advice about Ubuntu:

First of all, introductions: I'm Dave Jones. Some of you will know me from things like picamera, piwheels, pisense, gpio-zero and so forth (he says, sounding like Troy McClure). Nowadays, I'm also on the Canonical Foundations team, with responsibility for Ubuntu on the Pi which means:
You can blame me for a lot of the things mentioned on this thread!
This is probably the wrong place to discuss a lot of this; there's absolutely no point complaining to the fine folks at the Pi Foundation about Ubuntu. Bug me instead (see below for more information on how to bug Dave)!
As already mentioned by others, https://ubuntuforums.org/ and https://askubuntu.com/ are good places to ask about things like this. In particular, I trawl the "raspberrypi" tag on the latter in spare moments (which are few and far between in the run-up to a release, but will be a bit more plentiful now).

For me, the same SD card from rPi4-4 worked without any modification on the new 8GB ("Raspberry Pi 4 Model B Rev 1.4" ), https://linux-hardware.org/?probe=c47edd2fad

Don't know if,in my case , trying the Raspbian SD card first was the reason for no error while using the Ubuntu (20.04) card ...
Why not try a Raspbian first, and check if the Ubuntu 18.04 card ( that was working on the 4GB model) boots up without throwing errors on the 8GB model?

what is 'The new power supply'? which model?

There is no new power supply, there is a change to the power regulators on the 8GB Pi4B, that change plus some others required a firmware update, which the old OS doesn't have, hence won't boot.

Updates:
Thank you all for your replies and this is a list of the steps that I've done trying to fix this issue but unfortunately none of them worked for me :
a fresh install of Ubuntu 18.04.4 , and then use the following command to update all package and firmware:

• sudo apt update

• sudo apt upgrade

• sudo rpi-update

the commands was successfully executed no error reported.
insert again the ubuntu 18.04.4 SDCard into the RPI4-8gb and i got the same issue.

Conclusion
the RPI4-8gb, is unable to boot ubuntu 18.04.4, and referring the the reply of timg236 the only way to make it boot is to wait for canonical to release a kernel update that support the new power circuitry,

PS: the issue is only related to ubuntu 18.04.4. Ubuntu 20.04 and Raspberry PI OS work fine

Has there been any progress on this? I'm having the same issue.

I've gone with a Ubuntu 20 install for the time being, but it's for ROS. ROS noetic won't install as it's not been released for ARM64 versions yet (I think, because it wont let me install it) and compiling from source is a lot of effort.

Also, my entire ecosystem is based on ROS Melodic, as yet i don't know if the messages are compatible between the two systems like they are between Kinetic and Melodic.

In short, a working Ubuntu 18 for the pi4 8Gb would be very handy right now.

A workaround -

James Chambers did some fine work before Ubuntu 18 was officially supported on the pi 4, his version, last updated 25th of February boots fine. Looking at the github page - https://github.com/TheRemote/Ubuntu-Ser ... l/releases He seems to have ironed out the vast majority of all the bugs.
