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 – 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 – 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 →

ARM64 – Pine64 – Not Exactly ‘Compact’..

Adventures With Linux ™ Posted on June 7, 2016 by RGJune 7, 2016

I recently obtained one of the newly-released (- to the ‘public’..) Pine64 ARM64 systems…    My first reaction, was that it is a bit on the large side..  The board is over twice the size of the Odroid C2.. As usual, the ‘standard’ U-Boot was a heavily-customised old version, that only mounted Android-format Kernel ‘blob’s, but a hacked … Continue reading →

ARM64 – Odroid C2 U-Boot – More Progress..

Adventures With Linux ™ Posted on May 23, 2016 by RGMay 23, 2016

Thanks to an additional U-Boot patch from Carlo Caione, it is now possible to (partially) boot the mainline Kernel from U-Boot on an eMMC module, as well as from SDcard..    Patch details here:  https://www.mail-archive.com/u-boot@lists.denx.de/msg213468.html => mmc info Device: <NULL> Manufacturer ID: 15 OEM: 100 Name: BGND3 Tran Speed: 52000000 Rd Block Len: 512 MMC version 5.0 High … Continue reading →

ARM64 – Odroid C2 – U-Boot MMC Support..

Adventures With Linux ™ Posted on May 16, 2016 by RGMay 16, 2016

After the initial patches to provide basic U-Boot support for the C2, as mentioned in a previous article – there is now a further patch, to enable MMC support.    Details at https://www.mail-archive.com/u-boot@lists.denx.de/msg212503.html I have applied this additional patch, and for SDcard-based systems, it works: U-Boot 2016.05-rc3 (May 14 2016 – 21:06:28 -0700) odroid-c2 aarch64-linux-gnu-gcc (GCC) 5.3.1 20160212 … Continue reading →

ARM64 – Odroid C2 U-Boot – Latest..

Adventures With Linux ™ Posted on May 7, 2016 by RGMay 7, 2016

I discovered there was a later version (6) of the U-boot patch for the Odroid C2, and also – after more research – found the reason for the compile error… It turns out that the GIT version (May 5, 2016) of U-boot currently needs two patches.. The first one is to provide psci_system_reset for armv8, and details … Continue reading →

ARM64 – Pi3 64-Bit Tribulations.. Too Soon for Stability..

Adventures With Linux ™ Posted on April 15, 2016 by RGApril 15, 2016

I had ordered a Raspberry Pi 3 back in March in the hope that it would be a useful exercise in 64-bit on a different chipset..    I was (somewhat) disappointed to find that there was no initial 64-bit support, and indeed that I had been a bit of a pioneer in even running armv7 code on my … Continue reading →

ARM – Kernel 4.4-rc4 on the BananaPro..

Adventures With Linux ™ Posted on December 14, 2015 by RGDecember 14, 2015

Just got a ‘BananaPro‘ ARMv7 board, and updated it to Kernel 4.4-rc4 (from kernel.org) and Fedora 23. More details are here:  http://linux-sunxi.org/LeMaker_Banana_Pro I compiled U-Boot from the latest (2015.10) released version, from ftp.denx.de/pub/u-boot/ : # cd u-boot # make Bananapro_defconfig # make ARCH=arm CROSS_COMPILE=arm-linux-gnu- (or whatever cross-compiler you are using) Then as root, copy to the SDCard … Continue reading →

ARM64 – Dragonboard 410c – Now with U-Boot..

Adventures With Linux ™ Posted on November 10, 2015 by RGNovember 12, 2015

One of the shortcomings of the DragonBoard 410c was that it relied on the Android-phone-centric fastboot for any Kernel updates, but now there is a version of U-Boot available, thanks to Mateusz Kulikowski.. This is very much a work-in-progress, but I thought I would give it a try… I started with the version at https://github.com/hallor/u-boot/tree/dragonboard-2015.11.01, and made … Continue reading →
