ARM – Another Source for Rootfs Images..

Adventures With Linux ™ Posted on April 26, 2016 by RGApril 26, 2016

If you need a particular rootfs for an ARM7 or ARM64 device, there is a source of these at http://libguestfs.org/download/builder/ As an example, for Fedora 23 aarch64, then download the http://libguestfs.org/download/builder/fedora-23-aarch64.xz file, and then expand it (I use ark..)   This will give you a file fedora-23-aarch64, and simply rename this to fedora-23-aarch64.img. As the Fedora aarch64 images … Continue reading →

ARM64 – Pi3 Success – Almost..

Adventures With Linux ™ Posted on April 26, 2016 by RGApril 26, 2016

After more ‘investigation’, I managed to find a working U-Boot for a 64-bit boot of the Raspberry Pi 3, by copying it from the boot directory of this: http://www.tom-yam.or.jp/rpi3/rpi3-arm64-debian-20160414.img.xz found towards the end of the latest 64-bit thread on the Pi Forum: https://www.raspberrypi.org/forums/viewtopic.php?f=72&t=137963&sid=cd15abd8d4dd2a2d5c517f47a3e4f5e4&start=125 .  Thanks to xyinao for putting it all together.. I copied the kernel Image … Continue reading →

x86_64 – UP Board – Intel 64-bit, Size of a Pi..

Adventures With Linux ™ Posted on April 19, 2016 by RGApril 19, 2016

Being the pioneer/masochist type (aka ‘early-adopter’..), I was intrigued by the new Intel Atom x5-Z8350-powered UP Board, and now have one on (pre)order.. Basic info, with too much graphics..  http://www.up-board.org/specifications/ Not much info on their forum, yet, but it does have UEFI, so (speculation!) should boot with good old GRUB..  One thing it does not have is … 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 →

ARM64 – Geekbox – 8-Cores and a UART Gotcha..

Adventures With Linux ™ Posted on April 8, 2016 by RGApril 8, 2016

I recently acquired on of the rather quirky Geekbox ARM64 devices, together with the oddly-named ‘Landingstrip’ expansion board.. http://www.cnx-software.com/2015/11/19/geekbox-is-a-hackable-android-and-linux-tv-box-powered-by-rockchip-rk3368-soc/ http://forum.geekbox.tv/ The similarity in overall design to the ARMv7 Radxa Rock2 will be seen from the photo: If you are ordering one, it is worth getting the USB/UART connector as well, as the 3-pin micro flat-pin connection is … Continue reading →

ARM – Radxa Rock2 – Powerful, but Confused..

Adventures With Linux ™ Posted on February 24, 2016 by RGFebruary 24, 2016

Recently took delivery of a Radxa Rock2 ARMv7 system, based on the RX3288 Cortex A17 chipset.. The system comes with a version of Android installed on the onboard eMMC, but I managed – after a bit of work – to install Fedora 23 on an SDcard and get it to boot onto that..      At this point, I … Continue reading →

UDEV – Getting an Old Scanner to Behave..

Adventures With Linux ™ Posted on February 20, 2016 by RGFebruary 20, 2016

I recently acquired a vintage (2006?) Minolta Elite 5400 II scanner, and – according to the VueScan support info, I needed to ”set up libusb device protections”..   That info included a link to a somewhat ancient SANE USB support page – last changed in 2003!.. That rang a bell, and I guessed that I had to mess … Continue reading →

ARM – Configs for Odroid U3 and CuBox-i4Pro..

Adventures With Linux ™ Posted on February 3, 2016 by RGFebruary 3, 2016

I have just posted copies of recent kernel configs for the Odroid U3 and CuBox-i4Pro.. Odroid U3 – Kernel config for 4.4 :   http://pastebin.com/NveRajaZ CuBox-i4Pro – Kernel config for 4.4.1:  http://pastebin.com/Kbexi0A5 These do not include working WiFi, as 2.4GHz is pretty useless at my location… Robert Gadsdon.   February 2, 2016.

Fedora – Getting Rid of Unwanted ‘virtbr0’

Adventures With Linux ™ Posted on January 28, 2016 by RGJanuary 31, 2016

I did a clean install of Fedora 23 on my new ‘built from recycled components‘ crash-and-burn test system recently, and all went reasonably well – apart from – apparently – having to re-partition an already-partitioned drive (!)… After booting for the first time, I found that a ‘bridged’ network link – virtbr0 – was active..    As I … Continue reading →

NVIDIA – Latest 352.xx Driver – OK with Kernel 4.5-rc1..

Adventures With Linux ™ Posted on January 25, 2016 by RGJanuary 25, 2016

Just installed the latest NVIDIA driver – 352.79 – on the test system, and it compiles and runs OK with Kernel 4.5-rc1.. Release notes etc. are here:  http://www.nvidia.com/download/driverResults.aspx/97645/en-us I had been running the ‘beta’ driver 361.18, but found that this was using up large amounts of memory (13GB, out of 16GB) when running VMware and Firefox, and … Continue reading →
