in my Hackweek project[1] I tested Orange Pi PC board[2] with openSUSE. This is what I found:

There is Tumbleweed image with downstream kernel 3.4.39 [3] - it works with problems, I hit some incompatible IOCTL in V4L2 driver and kernel firmware loading does not work - the kernel can be recompiled from these sources [4]

Adding support to mainline is in progress: - U-boot 2016.01-rc2 can boot

Does -rc1 build, too? Then please submit an SR to Base:System u-boot adding the sub-package now (see pre_checkin.pl).

- I recompiled Tumbleweed kernel with patches from lkml[5]. It boots with gpio and mmc card working. There seems to be also some patches for usb support, but I was not able to identify, what patch exactly is needed.

Tumbleweed is at 4.3.0. Have you tried 4.4-rcX from Kernel:HEAD [9]? We had a report from another Hackweek project that USB on Cubietruck (A20) was not working in 4.3.0 but in ~4.4.rc3. You could also try to get Kernel:linux-next [10] building (still new), which would include all queued maintainer patches. Once some kernel is building the next steps would be Base:System/dtb-source (pre_checkin.sh) and openSUSE:Factory:ARM/JeOS.

I also tried to package OpenCV 3.0 library with NEON support [6] - the package is here [7], it needs more work on qt5 spec file

%ifarch %arm aarch64 -DENABLE_VFPV3=ON \ -DENABLE_NEON=ON \ %endif This looks problematic to me. For one, armv6hl does not have VFPv3 or NEON, so %arm seems a bad choice. For another, armv7hl cannot rely on NEON instructions at compile time, it needs to test at runtime whether they work on the target system - you'll need to check what ENABLE_NEON actually does, enabling detection or hardcoding of those features. Cheers, Andreas

- in my python code[8] I got about 25% higher fps compared to OpenCV 2
