ARM – Kernel 4.0-rc1 – Not Much Joy….Yet..

Adventures With Linux ™ Posted on February 23, 2015 by RGFebruary 23, 2015

Tried Kernel 4.0-rc1 on the CuBox-i4 Pro (from kernel.org) and the Odroid U3 (from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-4.0.y), and the results are a bit of a mixed bag.. The CuBox boots OK, but – although eth0 appears to be present – networking doesn’t work.. Fedora release 22 (Twenty Two) Kernel 4.0.0-rc1 on an armv7l (ttymxc0) ……………. [root@rgcubox ~]# uname -a … Continue reading →

ARM – Raspberry Pi ‘Classic’ – Device Tree Kernel Compile..

Adventures With Linux ™ Posted on February 22, 2015 by RGFebruary 22, 2015

After my tests compiling the new armv7 Pi 2 Kernel – with ‘device tree’ – I decided to try the same with the ‘classic’ armv6 Pi (B+).. You will need the latest version of the Pi /boot files, including the latest config.txt with the necessary parameters for device tree boot, sound config, etc.. For cross-compilation, I created … Continue reading →

ARM – Raspberry Pi 2 – Kernel Compile..

Adventures With Linux ™ Posted on February 19, 2015 by RGFebruary 19, 2015

Finally got the Raspberry Pi 2, and installed Fedora 21 (armv7hl) with no problems..    Temporarily used object code 3.18.7-v7+ from the repository, and then tested kernel compile options.. The system seems (so far..) to be relatively sluggish compared to my other quad-core armv7 systems..   Compiling on the Pi 2 itself seemed relatively slow, but at least it … Continue reading →

ARM – Kernel 3.19 for Odroid U3 – With Fan Control..

Adventures With Linux ™ Posted on February 11, 2015 by RGFebruary 11, 2015

Updated the Odroid U3 to (patched) Kernel 3.19, from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Thanks to work by tobiasjakobi, this now includes the preliminary patches – updated for 3.19 – for fan control on the Odroid U3, originally posted by Lukasz Majewski at http://www.spinics.net/lists/linux-samsung-soc/msg42259.html So, (on a Fedora 21 system) you can now control the fan, as follows: # echo “0” … Continue reading →

Adventures With Linux ™ Posted on February 8, 2015 by RGFebruary 8, 2015

Just updated the CuBox i4-Pro to Kernel 3.19-rc7 – using the standard code from kernel.org.. with device-tree boot using zImage and imx6q-cubox-i.dtb Only tested ‘headless’ access, so far.. Fedora release 21 (Twenty One) Kernel 3.19.0-rc7 on an armv7l (ttymxc0) ……………………..

ARM – Odroid U3 to 3.19-rc7 – Fan ‘Fixed’?

Adventures With Linux ™ Posted on February 5, 2015 by RGFebruary 5, 2015

Updated the Odroid U3 to Kernel 3.19-rc7, from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Had to ‘refresh’ the config, by # make exynos4412_odroid_defconfig, and then (re)enable selinux etc… One feature is that the CPU fan no longer runs constantly, but I need to do more tests, to see if it is now capable of running at all..    The temperature is OK, at … Continue reading →

ARM – New Raspberry Pi 2 – ARMv7 at Last..

Adventures With Linux ™ Posted on February 2, 2015 by RGFebruary 2, 2015

For those who have a new Raspberry Pi 2 on order – as I have – the kernel source is now available, at https://github.com/raspberrypi/linux/tree/rpi-3.18.y-rebase. To get the correct config, start with # make bcm2709_defconfig For me, one of the additional benefits is that it is ARMv7, which should support the standard up-to-date Fedora 21 distro, instead of … Continue reading →

Updated the Odroid U3 to the patched version of 3.19-rc5, from here: https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Fedora release 21 (Twenty One) Kernel 3.19.0-rc5 on an armv7l (ttySAC1) ………………..

Kernel 3.19-rc4 – OK on CuBox-i4 Pro.. No fixes yet for NVIDIA and VMware on x86..

Adventures With Linux ™ Posted on January 12, 2015 by RGJanuary 12, 2015

Updated the test system to Kernel 3.19-rc4, and the same comments apply as for -rc3..  Still no fixes for NVIDIA and VMware, yet.. I tried the CuBox-i4 Pro with a ‘standard’ kernel from kernel.org, rather than the ‘patched’ version used previously, and it booted OK.. Fedora release 21 (Twenty One) Kernel 3.19.0-rc4 on an armv7l (ttymxc0) …………. … Continue reading →

Kernel 3.19-rc3, ‘Lockup’ Bug, Latest..

Adventures With Linux ™ Posted on January 6, 2015 by RGJanuary 6, 2015

Updated the test system to Kernel 3.19-rc3, and there is still no fix for VMware (11.0) and the latest NVIDIA (340.65 and 346.22) drivers…     The NVIDIA problem will involve getting around a GPL-incompatible module issue.. FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol ‘__cachemode2pte_tbl’ 3.19-rc3 installs and runs OK on the CuBox-i4 Pro: $ uname -a Linux … Continue reading →
