Hardware – UART Gotcha for SOCs….

Adventures With Linux ™ Posted on July 14, 2023 by RGJuly 14, 2023

Not specifically Linux-related, but a frustration nonetheless.. This is documented elsewhere, but is often buried in other posts/articles/opinions.. Connecting a UART/USB cable/adapter to a SOC should be relatively simple, except that certain vendors now insist on a default speed of 1500000 instead of the traditional 115200.. I have been testing one of the ‘new’ RK3588-based systems, and … Continue reading →

ARM64 – Rock Pi N10 – Finally Booting From NVME..

Adventures With Linux ™ Posted on July 5, 2023 by RGJuly 5, 2023

I had managed to get Fedora running on my Rock Pi N10 some considerable time ago, but still was frustrated by the – apparent – lack of support for NVME, despite the slot for one in the chassis, and u-boot commands included..  I had posted this question to the RADXA Forum, but did not get a useful … 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 – 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 →

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 – Odroid C2 – Patches for USB..

Adventures With Linux ™ Posted on January 18, 2017 by RGJanuary 18, 2017

Thanks to Heiner Kallweit for info on two USB patches for the Odroid C2, and thanks to John Youn for the patches themselves..  They can be found at http://www.spinics.net/lists/linux-usb/msg151687.html and http://www.spinics.net/lists/linux-usb/msg151688.html . I have applied these to Kernel 4.10-rc4 (including the Ethernet TX patch) and now USB is working, and detects/connects devices – sort of.. Plug in … Continue reading →

ARM64 – Kernel 4.10-rc4 on Odroid C2 – Ethernet Still Needs DTS Patch..

Adventures With Linux ™ Posted on January 17, 2017 by RGJanuary 22, 2017

Just updated the Odroid C2 to Kernel 4.10-rc4, but the Ethernet hang problem still persists..   Applied the dts Ethernet TX patch (see http://rglinuxtech.com/?p=1872 ) , and it works OK now.. There seems to be a bit of a backlog of Meson/GXBB patches, and I read that the Ethernet TX fix was supposed to be merged with -rc4, … Continue reading →

ARM64 – Odroid C2 – Kernel 4.10-rc Config Example..

Adventures With Linux ™ Posted on January 15, 2017 by RGJanuary 15, 2017

As Odroid C2 support by the ‘mainline’ kernel is – hopefully – nearing completion, I have put a sample of my Kernel config at http://pastebin.com/XWfMEWHx . The C2 is used for ‘headless’ operation, at present, and USB still does not work..    The kernel is 4.10-rc3, with the ‘Ethernet-TX’ dts patch applied.. (see http://rglinuxtech.com/?p=1872 ). Robert Gadsdon.   January … Continue reading →

ARM64 – Odroid C2 – Working U-Boot..

Adventures With Linux ™ Posted on January 15, 2017 by RGJanuary 15, 2017

Thanks to Heiner Kallweit, there is now a functional version of U-Boot for the Odroid C2, at https://github.com/hkallweit/u-boot .. I have installed it on my C2 (eMMC) and it works fine..    Nice to have a functioning > saveenv command, at last.. U-Boot 2017.01-rc3 (Jan 14 2017 – 02:22:15 -0800) odroid-c2 DRAM: 2 GiB MMC: meson_mmc: 0, meson_mmc: … Continue reading →
