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 →

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 →

ARM64 – 4.14-rc1 Problems..?

Adventures With Linux ™ Posted on September 18, 2017 by RGSeptember 18, 2017

Kernel 4.14-rc1 has been stable on the x86_64 test system, but when I tried updating the Odroid C2 (ARM64) I saw a lot of mmc and other errors reported.. ………. [ OK ] Started File System Check on Root Device. Starting Remount Root and Kernel File Systems… mmcblk0: response CRC error sending r/w cmd command, card status … Continue reading →

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 →

Kernel – 4.10-rc2 Out – OK With aarch64, now..

Adventures With Linux ™ Posted on January 2, 2017 by RGJanuary 2, 2017

Kernel 4.10-rc2 has been released, and it has a very small number of changes from -rc1:  http://lkml.iu.edu/hypermail/linux/kernel/1701.0/00069.html I suspect that the major reason for this release is to fix the embarrassing compile fail with ARM64/aarch64, and it does compile OK now (tested on the Odroid C2).. Robert Gadsdon.   January 2, 2017. … Continue reading →
