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 →
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 →
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..

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 →
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.. ……….

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 →
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 →
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 →
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 →
Thanks to Tomas Pruzina, there is a patch for NVIDIA driver 375.26 with 4.10-rc kernels. Details, and the link, are here: https://devtalk.nvidia.com/default/topic/981993/linux/-patches-included-4-10-kernel-staging-/ Easiest way to get the patch is to select ‘Raw’ and just cut/paste the text.. I have tested this on kernel 4.10-rc2, and it compiles successfully (with a few warnings): ………………………….. /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-375.26.patched/kernel/nvidia-uvm/uvm8.c: In function ‘uvm_vm_fault_sigbus’: … Continue reading →
