ARM64 – Odroid C2 – A Better Ethernet Fix..

Adventures With Linux ™ Posted on December 2, 2016 by RGDecember 2, 2016

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 →

ARM64 – Odroid C2 – Boots with Linux-Next..

Adventures With Linux ™ Posted on November 18, 2016 by RGNovember 18, 2016

The ‘linux-next’ kernel branch has included the meson/gxbb mmc driver for some time, but the boot process hung on root disk access.     I tested with the latest (November 17) version, and this time, the boot process completed successfully: Fedora 25 (Workstation Edition) Kernel 4.9.0-rc5-next-20161117-c2 on an aarch64 (ttyAML0) The only patch I applied was the meson_ethernet_tx one … Continue reading →

ARM64 – Odroid C2 – Ethernet Fix, at Last..

Adventures With Linux ™ Posted on November 10, 2016 by RGNovember 10, 2016

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 →

ARM64 – Odroid C2 – Hack to Fix Ethernet Hangs..

Adventures With Linux ™ Posted on October 22, 2016 by RGOctober 22, 2016

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 →

ARM64 – Odroid C2 – New MMC Driver, Ethernet / USB Still Broken..

Adventures With Linux ™ Posted on October 20, 2016 by RGOctober 20, 2016

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 →

ARM64 – Multiple Meson MMC Mystery..

Adventures With Linux ™ Posted on October 15, 2016 by RGOctober 15, 2016

I was going to update the Odroid C2 to the latest patched kernel, but then found that the meson-mmc driver had mysteriously vanished from the source tree..     This – of course – makes the kernel pretty useless…    I did some research, but could not find any specific mention of the removal of this code, but then found … 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 →

Adventures With Linux ™ Posted on September 1, 2016 by RGSeptember 1, 2016

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 →

ARM64 – Odroid C2 U-Boot – More Progress..

Adventures With Linux ™ Posted on May 23, 2016 by RGMay 23, 2016

Thanks to an additional U-Boot patch from Carlo Caione, it is now possible to (partially) boot the mainline Kernel from U-Boot on an eMMC module, as well as from SDcard..    Patch details here:  https://www.mail-archive.com/u-boot@lists.denx.de/msg213468.html => mmc info Device: <NULL> Manufacturer ID: 15 OEM: 100 Name: BGND3 Tran Speed: 52000000 Rd Block Len: 512 MMC version 5.0 High … Continue reading →

ARM64 – Odroid C2 – U-Boot MMC Support..

Adventures With Linux ™ Posted on May 16, 2016 by RGMay 16, 2016

After the initial patches to provide basic U-Boot support for the C2, as mentioned in a previous article – there is now a further patch, to enable MMC support.    Details at https://www.mail-archive.com/u-boot@lists.denx.de/msg212503.html I have applied this additional patch, and for SDcard-based systems, it works: U-Boot 2016.05-rc3 (May 14 2016 – 21:06:28 -0700) odroid-c2 aarch64-linux-gnu-gcc (GCC) 5.3.1 20160212 … Continue reading →
