ARM64 – Pi4 – Finally, a fix for the USB Issues..

Adventures With Linux ™ Posted on September 3, 2021 by RGSeptember 3, 2021

I had spent far too much time trying to solve the Pi4 USB conundrum ( see https://rglinuxtech.com/?p=2922 ) but did recently find that the 5.14-rc kernels enabled the USB3 hub, although USB2 still failed to function.    I then updated u-boot to the ‘latest’ version, and now everything (finally..) works as it should, again..: Updated u-boot to latest … Continue reading →

ARM64 – Pi 4 USB Problems – And a Messy Fix..

Adventures With Linux ™ Posted on May 11, 2021 by RGMay 11, 2021

After some delay, I finally had a ‘good’ cooling solution for my 8GB Pi4, and resumed testing.. The last Kernel version I had running on it was 5.9-rc4, and everything seemed to be working OK (including 8GB of memory recognised). I then updated to 5.11.18, and found that none of the USB ports worked: # dmesg |grep … Continue reading →

ARM – Vim3-Pro – with EFI and Fedora 33..

Adventures With Linux ™ Posted on January 5, 2021 by RGJanuary 5, 2021

Recently acquired one of the Khadas VIM3-Pro arm64 SoCs, and was impressed with the level of documentation available.. Unfortunately – as is so often the case – this was all relentlessly Ubuntu-focussed, with a semi-proprietary kernel based on the 4.X kernel tree.. At least the U-Boot version was fairly recent, and appeared to support EFI etc.. The … Continue reading →

ARM64 – Fedora 33 Pre-release Kernel Boot Problem – and Workaround..

Adventures With Linux ™ Posted on August 26, 2020 by RGAugust 26, 2020

I have been testing Fedora 33 pre-release, and on x86_64 it seems relatively stable (usual caveats…) but on arm64 systems (Odroid N2 and Pi4) I found that after compiling a new kernel (5.8.3), the system booted, but login was impossible, and screen output was missing  (uart/console was OK). Kernels compiled with Fedora 32 all booted OK, and … Continue reading →

ARM64 – 8GB Pi4 – Fun with Fedora..

Adventures With Linux ™ Posted on July 18, 2020 by RGJuly 18, 2020

My 8GB Raspbery Pi 4 finally arrived, and I was looking forward to trying Fedora 32 and KDE/Plasma on it, and comparing it to the Odroid N2 from a few months back.. ( http://rglinuxtech.com/?p=2689 ) The Fedora 32 aarch64 install is supposed to support the Pi 4 now, but the resulting sdcard image failed to boot, with … Continue reading →

ARM64 – Odroid N2 – Latest U-Boot, Kernel 5.6-rc2, EFI, Fedora 31, Plasma/Wayland

Adventures With Linux ™ Posted on February 17, 2020 by RGFebruary 17, 2020

I have recently acquired an Odroid N2 (4GB) and managed – with some difficulty – to get it to run a ‘modern’ U-Boot, Kernel 5.6-rc2, with EFI support, and Fedora 31. This time, there were no clues from OpenSuse, and all the examples I found still used the ancient/custom Hardkernel u-boot and a kernel.img ‘blob. Fortunately, the … Continue reading →

ARM – Original Hikey Updated and Fixed – with Gotchas..

Adventures With Linux ™ Posted on September 9, 2019 by RGSeptember 9, 2019

After successfully updating and re-configuring the Odroid C2 to use Fedora uefi/grub2 to boot, I decided to try to do the same to the even-older Hikey SOC. This already booted using fastboot with an older version of grub, with manual configuration, but I wanted to use the standard (Fedora) boot process. I had read that there was … Continue reading →

ARM – Odroid C2 – Updated..

Adventures With Linux ™ Posted on August 19, 2019 by RGAugust 19, 2019

When the Odroid C2 was first released way back in 2016, I spent ages trying to get it to function correctly with a mainstream kernel, and tested innumerable development versions of U-Boot, including functionality that was working OK at that time, but that – for some reason – then failed to be included in the ‘mainstream’ U-Boot.. … Continue reading →

Fedora – F28 Upgrade on ARM64 – Fix for GPG Errors..

Adventures With Linux ™ Posted on July 6, 2018 by RGJuly 6, 2018

When doing a # dnf system-upgrade reboot on an ARM64 system you may encounter a stream of GPG errors, followed by reboot, without upgrade. To fix this, simply import the F28 GPG key in advance, as done for Rawhide: # rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-28-primary After this, the system-upgrade should proceed correctly..

ARM64 – Fedora 27, UEFI and Pi3..

Adventures With Linux ™ Posted on December 12, 2017 by RGDecember 12, 2017

I decided – after some time – to do some more with the Raspberry Pi 3, and set it up as a small network print server.. As there was now an ‘official’ version of Fedora 27 for the Pi3, I decided to use this..   Details are here, and links to aarch64 images are near the bottom of … Continue reading →
