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 →
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 →

After the – partial – success with the 96Boards Hikey, I tried the Qualcomm Dragonboard 410c, but the June 29 Linux-Next failed to boot successfully, with only one CPU initialising, and MMC errors, and eventual hang…. ……………………….. psci: failed to boot CPU1 (-95) CPU1: failed to boot: -95 CPU1: failed in unknown state : 0x0 psci: failed … Continue reading →
After some time, I decided to test the latest ‘Linux-Next’ with the 96Boards HiSilicon Hikey, and – this time – it booted successfully (headless), with networking..

I have tried the latest 4.7-next patched kernel, from https://github.com/anholt/linux/tree/bcm2837-64-next After some trials, I did manage to – just – get it to boot – after falling to an ’emergency console’, but the system is very unstable, with multiple recurring MMC errors.. …..

I recently obtained one of the newly-released (- to the ‘public’..) Pine64 ARM64 systems… My first reaction, was that it is a bit on the large side.. The board is over twice the size of the Odroid C2.. As usual, the ‘standard’ U-Boot was a heavily-customised old version, that only mounted Android-format Kernel ‘blob’s, but a hacked … Continue reading →
My ‘system disk’ (/dev/sda) started to show bad sectors, recently, and so I decided to replace it. The disk was around 8 years old, and had been in almost-continuous use.. I have not had to do this for some considerable time, and I think the last time was in the late-90s, and using LILO! (No convoluted grub2 … Continue reading →
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..

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 →
