tar xf linux-sunxi-sunxi-v3.4.24-r2.tar.gz
Quote from: crubille on February 07, 2013, 12:05:38 AMAt this point, i load- xenomai-188.8.131.52 with patchs for 3.0.36 and for 3.4.6.- the sunxi 3.0 and 3.4 kernels - the patch 3.4.1 ... up to 3.4.6 seems to be already applied on the 3.4 sunxi kernel. So it is not clear what is the closest linux vanilla kernel version.- appling the patch from the xenomai distribution on the sunxi kernels, there is not so many fails. Here are the files where the patchs cant obviously apply in either kernels: saving rejects to file arch/arm/include/asm/cacheflush.h.rej saving rejects to file arch/arm/include/asm/pgtable.h.rej saving rejects to file arch/arm/kernel/smp.c.rej saving rejects to file arch/arm/vfp/entry.S.rej saving rejects to file arch/arm/vfp/vfphw.S.rej and two more files from the sunxi 3.0.8 saving rejects to file arch/arm/vfp/vfpmodule.c.rej saving rejects to file kernel/sched.c.rejI start to look at these files.

Quote from: ehj666 on February 10, 2013, 02:55:57 AMFWIW, here is what I have managed so far.Notes: I had previously built a generic kernel and copied a13_defconfig from arch/arm/configs primarily based on the instructions found here:https://www.olimex.com/wiki/Build_Bootable_SD_Card_with_DebianI am using Ubuntu 12.04 as the build envirnonment.The latest kernal on which Xenomai appears to work is 3.0.36. Here are the build instructions up to needing to implement a high res timer.Code Select Expandmkdir kernelcd kernelgit clone https://github.com/linux-sunxi/linux-sunxi linux-sunxigit checkout v3.0.36cd ..My blog on this can be found here:http://lcncolinuxino.blogspot.com/

Quote from: uMinded on February 14, 2013, 11:15:25 PMWould anybody be willing to give my kernel a try? I think I am going to try and get a board next week if I can but it will be two weeks at best before I know if it works without any help.
