I have recently acquired an Odroid N2 (4GB) and managed – with some difficulty – to get it to run a ‘modern’ U-Boot, Kernel 5.6-rc2, with EFI support, and Fedora 31. This time, there were no clues from OpenSuse, and all the examples I found still used the ancient/custom Hardkernel u-boot and a kernel.img ‘blob. Fortunately, the … Continue reading →
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.. ……….

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 →
