The old meson Ethernet fix/patch/hack no longer applies cleanly to the latest (December 1) linux-next, but – fortunately – there is a ‘better’ patch available for the meson8b-dwmac driver itself.. Details can be found in this thread: http://lists.infradead.org/pipermail/linux-amlogic/2016-November/001675.html I have applied these patches to the December 1 linux-next tree, on the Odroid C2, and the Ethernet link … Continue reading →

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 →
I tried the latest ‘Linux-Next’ version, from https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/?id=refs/tags/next-20160913 and the C2 booted OK, but the Ethernet problem still persists.. ……… eth0: device MAC address 00:1e:06:33:13:6e meson6-dwmac c9410000.ethernet eth0: Link is Up – 1Gbps/Full – flow control rx/tx Fedora 24 (Workstation Edition) Kernel 4.8.0-rc6-next-20160913 on an aarch64 (ttyAML0) ………………… # uname -a Linux rgc2 4.8.0-rc6-next-20160913 #2 SMP PREEMPT … Continue reading →
