After some of the recent ‘Ethernet fix’ patches have not worked with more recent linux-next kernels, I have found one that – at least at the moment – does fix the ‘hang’ problem – again.. The patch is applied to meson-gxbb-odroidc2.dts, and can be found here: http://archive.arm.linux.org.uk/lurker/message/20161221.113134.3ac4d1e6.en.html I did have to revert this kasir_offset patch (…-R) to … Continue reading →
I had been trying to apply the latest round of Meson TX delay patches to the latest linux-next tree, but found that there seems to be a conflict with some of these.. The December 1 patched kernel now has some problems on my C2 with Ethernet traffic, so – for the time being – I have reverted … Continue reading →
Just updated the test system to VMware Workstation Pro 12.5.2, and it still fails to compile with Kernel 4.9-rc5 I have – so far – been unable to find any other patches for this issue, but fortunately the nasty hack I documented in the article for 4.9-rc4 still works.. https://rglinuxtech.com/?p=1838 The release notes for 12.5.2 are here: … Continue reading →
Thanks to Jerome Brunet, there is now a fix for the long-standing Ethernet hang problem on the C2.. Details are here: http://lists.infradead.org/pipermail/linux-amlogic/2016-November/001538.html The patch is an attachment – named ‘attachment.bin‘, and so will need to be renamed to something appropriate.. I applied this to the 4.9-rc3-derived version of the C2 patched kernel, from https://git.kernel.org/cgit/linux/kernel/git/khilman/linux-amlogic.git/log/?h=v4.10/integ.. There is a … Continue reading →
Updated the test system to Kernel 4.9-rc3, and the patch for NVIDIA mentioned in my article for -rc2 still works OK.. I Compiled 370.28 and 375.10 successfully.. As I could not find any patches for VMware – and the latest version 12.5.1 still fails to compile, I created a nasty hack myself.. Warning – This is not … Continue reading →
Updated the test system to Kernel 4.9-rc2, and both VMware (12.5.0) and NVIDIA (370.28 and 375.10) failed to compile..

I had been constantly frustrated by the Odroid C2 meson8b-dwmac Ethernet ‘hang’ problem, which has persisted over (at least..) eight different ‘patched kernel’ versions that I have tested.. The network link hung/stopped after a short time at full (1000Mbps) speed, and also – sometimes after a bit longer – at reduced (100Mbps) speed.. The driver does show … Continue reading →
After some of the code for the C2 has been removed from various git repositories, there is a new 4.9-rc1-based tree at https://git.kernel.org/cgit/linux/kernel/git/khilman/linux-amlogic.git/?h=v4.10/integ , which now includes the ‘new’ rewritten MMC driver. To select this, choose ‘Amlogic S905/GX* SD/MMC Host Controller support (MMC_MESON_GX)‘ in the kernel config.. …… Fedora 24 (Workstation Edition) Kernel 4.9.0-rc1-c2 on an aarch64 … Continue reading →

Decided to try the Odroid C2 with the latest Kernel, and recently-released patches for MMC support.. Used the (patched) version of 4.8-rc4 from here: https://github.com/ioft/linux/tree/c2 Thanks to umiddelb for producing this, which incorporates the (e)MMC support patches, and also includes patches providing the latest version of the dwmac_meson8b Ethernet driver, and associated mods to the device tree … Continue reading →
