As there is no later version of the Odroid-specific 4.0 kernel source available yet, I decided to test with the standard 4.0-rc3 from kernel.org, but the U3 booted – and then Panic‘d.. ………………………..

Now that the DreamPlug has a stable power supply (see previous post..) I decided to live dangerously and update the u-boot version and install a modern ‘device tree’ plus kernel.. It has been mentioned many times before that the u-boot update for a DreamPlug is fraught, and can result in a ‘brick’.. There should be a way … Continue reading →
I finally got my old DreamPlug working again, but found that the power would fail intermittently.. After checking for software faults, I tracked the problem down to the power supply cable ‘clip-on’ connector.. The problem was caused by the internal connection between the two external pins and the internal slide-on metal tabs being loose, and causing … Continue reading →
The CuBox-i4 Pro booted Kernel 4.0-rc1 OK, but – although eth0 was present – there was no network connection possible.. I found a similar problem described on the Linux Arm Kernel mailing list: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/325249.html According to the info there, I changed linux/arch/arm/mach-imx/mach-imx6q.c as follows: Around line 214, change clksel = ptp_clk == enet_ref ? IMX6Q_GPR1_ENET_CLK_SEL_ANATOP : IMX6Q_GPR1_ENET_CLK_SEL_PAD; … Continue reading →
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) …………….

I have hacked together a kernel-version-friendly fix for the latest NVIDIA driver (346.35) which works with Kernel 4.0-rc1 (and later) and also for previous kernel versions..
