ARM – Odroid U2 – 3.17 Boot, but no USB..

Adventures With Linux ™ Posted on October 10, 2014 by RGOctober 10, 2014

Tried the latest kernel.org 3.17 kernel with my Odroid U2, and managed to get it to boot successfully, but USB still doesn’t work, which is a show-stopper, as the Ethernet adapter is a USB-connected device.. Start with # make exynos_defconfig, and then select arch/arm/boot/dts/exynos4412-odroidu3.dtb when merging with zImage, etc… [ 0.000000] Booting Linux on physical CPU 0xa00 … Continue reading →

ARM – Odroid U2 – Finally an Up-to-Date Kernel?

Adventures With Linux ™ Posted on September 12, 2014 by RGSeptember 12, 2014

I had been frustrated by the apparent inability of the suppliers to provide anything other than an obsolete Ubuntu-centric 3.8+ kernel for the Odroid U2, and other kernels I had tested were somewhat ‘incomplete’… I finally managed to get a 3.17-r3 version from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.17.y This now includes the necessary ‘bits’ for the U3, which is functionally identical … Continue reading →

Dreamplug – Right Up-to-Date with 3.6-rc3..

Adventures With Linux ™ Posted on August 24, 2012 by RGAugust 24, 2012

APC – Fixing Fedora’s Rogue Fsck…

Adventures With Linux ™ Posted on August 23, 2012 by RGAugust 23, 2012

The ‘default’ Fedora 13 system for ARM mounts the root as nfs..   To change it to the (correct) ext3, modify /etc/fstab as follows: # cat /etc/fstab /dev/mmcblk0p2          /                       ext3    defaults        1 1 /dev/mmcblk0p1          /boot                   vfat    defaults        1 0 devpts                  /dev/pts                devpts  gid=5,mode=620  0 0 tmpfs                   /dev/shm                tmpfs   defaults        0 0 proc                    /proc                   proc    defaults        0 0 sysfs                   … Continue reading →

APC – And now – Fedora Linux..

Adventures With Linux ™ Posted on August 18, 2012 by RGAugust 18, 2012

After all the pioneering work done to get a compiled working version of the APC kernel by Mike Thompson from the Raspbian project, as described in a previous post, I now have Fedora Linux running on the APC. I had planned to be able to get Fedora 17 working, but the APC kernel (vintage 2010!) is just … Continue reading →

APC – Real Progress – Bootable Linux Kernel..

Adventures With Linux ™ Posted on August 17, 2012 by RGAugust 17, 2012

After excellent work done by Mike Thompson from the Raspbian project, there is now a set of patches and a config file available for the APC-supplied 2.6.32.9+ kernel source, which enables a working kernel to be compiled and run – although with limited functionality due to ‘missing’ device drivers..   More details at :  http://www.raspbian.org/ApricotImages To use this, … Continue reading →

APC – Final U-Boot tests, for the time being..?

Adventures With Linux ™ Posted on August 15, 2012 by RGAugust 15, 2012

Just to finally confirm that the U-Boot parameters were not in any way affection the APC boot – and therefore that the problem was in the APC’s kernel configuration, probably with the CONFIG_CMDLINE parameter in the original kernel’s .config file – I removed all the U-Boot parameters, as follows: WMT # setenv wmt.display.logoaddr; setenv logocmd; setenv wmt.gpo.lcd; … Continue reading →

APC – The Saga Continues….

Adventures With Linux ™ Posted on August 12, 2012 by RGAugust 12, 2012

On the hunch that there may be something within the U-Boot parameters that causes the boot-to-ram problem, I removed almost all the ‘wmt.xxx‘ parameters.   The only one remaining was wmt.usb.param=11:3, which enables the USB subsystem – as I was booting from a USB-attached ‘disk’.. You can effectively ‘remove’ U-Boot parameters by setting their values to <blank>: setenv … Continue reading →
