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 ?

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.. Thanks are due to juston_li for producing the actual code changes needed.. https://devtalk.nvidia.com/default/topic/813458/linux/linux-4-0-rc1-346-35-build-error-_cr4-functions-fix/ Unpack the NVIDIA driver: ./NVIDIA-Linux-x86_64-346.35.run -x Edit NVIDIA-Linux-x86_64-346.35/kernel/nv-pat.c Around line 34, change { unsigned long cr0 = read_cr0(); … Continue reading →
Just tested Kernel 4.0-rc1 – announced here: http://lkml.iu.edu/hypermail/linux/kernel/1502.2/04059.html As you will see – not much actual detail on what has changed, and I have already run into a couple of ‘issues’… The Radeon drm driver on my laptop refuses to load, and the boot hangs immediately with drm r600_ring_test [radeon] *ERROR* radeon: ring 0 test failed (scratch(0x8504)=0xFFFFFFFF) … Continue reading →
