I decided – after some time – to do some more with the Raspberry Pi 3, and set it up as a small network print server.. As there was now an ‘official’ version of Fedora 27 for the Pi3, I decided to use this.. Details are here, and links to aarch64 images are near the bottom of … Continue reading →
Kernel 4.14-rc1 has been stable on the x86_64 test system, but when I tried updating the Odroid C2 (ARM64) I saw a lot of mmc and other errors reported.. ………. [ OK ] Started File System Check on Root Device. Starting Remount Root and Kernel File Systems… mmcblk0: response CRC error sending r/w cmd command, card status … Continue reading →
Thanks to Heiner Kallweit for info on two USB patches for the Odroid C2, and thanks to John Youn for the patches themselves.. They can be found at http://www.spinics.net/lists/linux-usb/msg151687.html and http://www.spinics.net/lists/linux-usb/msg151688.html . I have applied these to Kernel 4.10-rc4 (including the Ethernet TX patch) and now USB is working, and detects/connects devices – sort of.. Plug in … Continue reading →
Just updated the Odroid C2 to Kernel 4.10-rc4, but the Ethernet hang problem still persists.. Applied the dts Ethernet TX patch (see http://rglinuxtech.com/?p=1872 ) , and it works OK now.. There seems to be a bit of a backlog of Meson/GXBB patches, and I read that the Ethernet TX fix was supposed to be merged with -rc4, … Continue reading →
As Odroid C2 support by the ‘mainline’ kernel is – hopefully – nearing completion, I have put a sample of my Kernel config at http://pastebin.com/XWfMEWHx . The C2 is used for ‘headless’ operation, at present, and USB still does not work.. The kernel is 4.10-rc3, with the ‘Ethernet-TX’ dts patch applied.. (see http://rglinuxtech.com/?p=1872 ). Robert Gadsdon. January … Continue reading →
Kernel 4.10-rc2 has been released, and it has a very small number of changes from -rc1: http://lkml.iu.edu/hypermail/linux/kernel/1701.0/00069.html I suspect that the major reason for this release is to fix the embarrassing compile fail with ARM64/aarch64, and it does compile OK now (tested on the Odroid C2).. Robert Gadsdon. January 2, 2017. … Continue reading →
There is now an ‘official’ fix for the 4.10-rc1 compile failure with ARM64/aarch64, from Al Viro, and the patch itself is available here: https://git.kernel.org/cgit/linux/kernel/git/viro/vfs.git/commit/?h=arm64-fix&id=b4b8664d291ac1998e0f0bcdc96b6397f0fe68b3 I have applied this to kernel 4.10-rc1 on the Odroid C2, and the kernel compiles successfully.. Robert Gadsdon. December 27, 2016. … Continue reading →
After applying the aarch64 compile fix (see previous article) I was able to compile Kernel 4.10-rc1 on the Odroid C2, and it boots OK (headless..), and the Ethernet link stays up, but still needs the TX patch.. (updated, as the link did still hang – eventually.. RG).. ……….. meson8b-dwmac c9410000.ethernet eth0: Link is Up – 1Gbps/Full – … Continue reading →
Tried compiling Kernel 4.10-rc1 for aarch64, and got – literally – hundreds of errors: …… ./include/linux/sched.h:3299: Error: unknown mnemonic `return’ — `return test_ti_thread_flag(task_thread_info(tsk),flag)’ ./include/linux/sched.h:3300: Error: junk at end of line, first unrecognized character is `}’ ./include/linux/sched.h:3302: Error: unknown mnemonic `static’ — `static inline void set_tsk_need_resched(struct task_struct*tsk)’ ./include/linux/sched.h:3303: Error: junk at end of line, first unrecognized character is … Continue reading →
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 →
