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

Adventures With Linux ™ Posted on by

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 by

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 →

Adventures With Linux ™ Posted on by

Updated to the latest VMware Workstation Pro version – 12.5.0, and it compiles OK with kernel.org kernel 4.7 (4.7.3) and also with 4.8 (4.8-rc6).

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 →

X86_64 – UP Board – ‘Cherry Trail’ – Sound – Working..

Adventures With Linux ™ Posted on by

The only missing OS component on the new UP Board (x5-Z8350) was that sound (HDMI) was not present..    After a bit of digging, I found some patches for Kernel 4.5, and a later patched kernel version that was supposed to work.. I tried the patched version of 4.7.0 from here:  https://github.com/plbossart/sound/tree/byt-cht-hdmi-v4.7  but found that the compile failed: … Continue reading →

ARM – Next CHIP – Waiting for Hynix NAND Support..

Adventures With Linux ™ Posted on by

Tested some of the kernel versions possible (or not..) for the Next CHIP ARMv7, with mixed results..     I added an Ethernet/USB device (ax88179-based) on the USB hub, and the network connection works fine.. Linux-Next does not yet have the drivers for the Hynix NAND in the CHIP, although – with the rootfs separate on a USB stick … Continue reading →

ARM – Next CHIP ARMv7 – First Impressions..

Adventures With Linux ™ Posted on by

After pre-ordering one many months ago, I finally got my Next CHIP ARMv7 system in the post.. It certainly is fairly small, but seems well-constructed..     Details are at http://docs.getchip.com/chip.html#chip-hardware After connecting the UART/USB cable, as normal, the system booted into a cut-down version of Debian..   There is no hdmi, or sdcard connector, or Ethernet, but the wi-fi … Continue reading →
