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 →
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 →

After all the fuss with ancient versions of Linux on the APC, I now have the very latest Linux – 3.6-rc3 – running on the Dreamplug..: Fedora release 17 (Beefy Miracle) Kernel 3.6.0-rc3 on an armv5tel (ttyS0) rgdreamplug login: …………. # uname -a Linux rgdreamplug 3.6.0-rc3 #1 Fri Aug 24 00:20:25 BST 2012 armv5tel armv5tel armv5tel GNU/Linux … Continue reading →
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 →
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 →
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 →
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 →
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 →
