Recently attempted to update the Pi2 to Kernel 4.4-rc5, and encountered a problem.. The more recent proprietary Raspberry Pi 2 kernels have switched to using ‘DTB Overlays’ to control various components, but these are – currently – unsupported by U-Boot.. Booting the kernel with U-Boot results in mmc errors, and register dump: ……………….. timeout waiting for hardware … Continue reading →
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 →
Just updated the test system to VMware 12.1.0 – Release notes are here: https://pubs.vmware.com/Release_Notes/en/workstation/12pro/workstation-121-release-notes.html Frustratingly, this release still has a runtime (# vmware) incompatible with Fedora 23.. The original workaround was documented in an earlier article – http://rglinuxtech.com/?p=1601 – but the Fedora 23 library versions have now changed, so the copy commands are now (as of December … Continue reading →
Updated to Kernel 4.4-rc1 on the test system, and VMware 12.0.1 and NVIDIA 358.09 both compile and load/run OK.. I did get an error from vmnet, but – so far – it appears to be working OK despite this: $ vmnet1: set_features() failed (-1); wanted 0x0000000000004000, left 0x0000000000004800 vmnet8: set_features() failed (-1); wanted 0x0000000000004000, left 0x0000000000004800 $ … Continue reading →
Updated the DragonBoard 410c to Kernel 4.2.4: # git clone https://git.linaro.org/landing-teams/working/qualcomm/kernel.git -b release/qcomlt-4.2 and this version boot/runs OK.. I am running these systems ‘headless’, so have not been able to test monitor/display capabilities.. Fedora 23 (Twenty Three) Kernel 4.2.4 on an aarch64 (ttyMSM0) ……………… # uname -a Linux rg410c 4.2.4 #1 SMP PREEMPT Wed Nov 11 04:12:36 … Continue reading →
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 →
Although VMware 12.0.1 was installed OK, the desktop app (/usr/bin/vmware) fails, with – frustratingly – no error shown.. According to various comments found, this is due to a change to GCC version 5.1.1 in Fedora 23.. Thanks to Vincent Cojot, on the sgros.blogspot.com blog, there is a slightly convoluted workaround, which basically involves replacing the VMware versions … Continue reading →
Updated to Kernel 4.3 ‘Final’ and the latest versions of VMware (12.0.1) and NVIDIA (tested with 352.55) install and load/run OK, without the need for any patches.. Brief details of changes from -rc7 are here: http://lkml.iu.edu/hypermail/linux/kernel/1511.0/00204.html $ uname -a Linux rglinux-i7 4.3.0 #1 SMP Sun Nov 1 17:27:46 PST 2015 x86_64 x86_64 x86_64 GNU/Linux Robert Gadsdon. November … Continue reading →
UPDATE: After more tests, I found a solution.. Rather than ‘update’ from 12.0.0 to 12.0.1, you have to deinstall 12.0.0 first: # vmware-installer –uninstall-product vmware-workstation – remembering to answer ‘yes‘ to the ”Do you wish to keep your configuration files?” message. Then install 12.0.1 as a new install.. # ~/VMware-Workstation-Full-12.0.1-3160714.x86_64.bundle Now everything seems to be working OK, … Continue reading →
Installed Mariadb, Apache etc, and phpMyAdmin on the Fedora 22 Intel i7 system, and the database was all OK, but phpMyAdmin showed a blank window.. Searching for this issue produced a wealth of reasons – usually ‘operator/config’ problems.. My config was just a clone of a known/good system, and I eventually found a simple reason for the … Continue reading →
