Kernel – GCC 8 Tests – Not Quite Ready…

Adventures With Linux ™ Posted on by

I decided to try updating a crash-and-burn test system to Fedora 28 (early-beta..) as this included GCC 8 (currently 8.0.1), to see how well the Kernel (4.16-rc6) compiled.. There were a lot of warnings generated: …………………… CC [M] drivers/rtc/rtc-pcf8523.o CC drivers/usb/core/file.o CC drivers/video/hdmi.o CC [M] drivers/rtc/rtc-pcf8563.o drivers/video/hdmi.c: In function ‘hdmi_spd_infoframe_init’: drivers/video/hdmi.c:171:2: warning: ‘strncpy’ specified bound 8 equals … Continue reading →

ARM – DreamPlug Kernel Compile – Correction..

Adventures With Linux ™ Posted on by

Thanks are due to Marcus Roeder, who pointed out an error in my DreamPlug kernel compile workflow (http://rglinuxtech.com/?p=1354).. The make LOADADDR.. command was incorrect, and would result in less system memory being available.. The correct command is: make LOADADDR=000008000 uImage – and this will result in all the memory being available: # free total used free shared … Continue reading →

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

Adventures With Linux ™ Posted on by

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 by

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 – Odroid U3 Kernel Compilation..

Adventures With Linux ™ Posted on by

This is a workflow for compilation of a kernel + device tree for the Odroid U3.   There are other ways of doing this, but this one works, for me.. Compilation works fine on the device itself, so no need for cross-compilations.. This is for a device with root filesystem and boot partition on one SDcard.. Source from: … Continue reading →
