  1. there are still some issues with hdmi but they should be fixed in near future for now if hdmi is a problem you can try RC kernel version. i have to warn that 5.1 kernel have bare minimum stuff compiled in to it and if you want something more fancy then you will face some problems.
  2. @martinayottewould it be possible to shared git diff for anyone else who would like to start experimenting with 5.1.y branch?
  3. i guess everyone can do this, it is just time question. If you are more experienced on that subject then you do it faster. have you seen this post ?
  4. @martinayotte how to change repo? I have tried but build failed once i change branch in source config. Also while testing @megous kernel i noticed that cpu max freq was 1.49, i guess there is some patch for dtb file which needs to be applied durring compile of dbt as it had made that scale down change in freq
  5. @megi thank you, you were right, video is working as it should with your kernel.

P.S wifi device is also present without any firmware file rename hacks
  6. ok, I didn't expected that this would work but it did on opi3 armbian build git clone https://github.com/megous/linux.git cd linux make oldconfig make -j5 make Image make modules_install mv /boot/Image /boot/Image_backup cp arch/arm64/boot/Image /boot/Image reboot ---- edid still a problem root@orangepi3:~# cat /sys/class/drm/card0-HDMI-A-1/edid root@orangepi3:~# cat /sys/class/drm/card0-HDMI-A-1/modes 1024x768 800x600 800x600 848x480 640x480 root@orangepi3:~# uname -a Linux orangepi3 5.1.0-rc4+ #1 SMP Fri Apr 12 09:34:47 UTC 2019 aarch64 GNU/Linux @megi how about those patches https://lkml.org/lkml/2019/4/5/857 ? any changes that one of those 2 branches opi3-5.1 or orange-pi-5.1 have them ? and what difference between them ?
  7. @megi i guess you compile kernel manually and put it to correct place ? i just have changed https://github.com/armbian/build/blob/master/config/sources/sun50iw6.conf to your suggested branch and fired up armbian image creation which have failed. scripts/Makefile.lib:311: recipe for target 'arch/arm64/boot/dts/allwinner/sun50i-h5-nanopi-m1-plus2.dtb' failed scripts/Makefile.build:486: recipe for target 'arch/arm64/boot/dts/allwinner' failed Makefile:1228: recipe for target 'dtbs' failed
  8. I almost started believe like in this experiment https://www.youtube.com/watch?v=2uHNSuGeTpM it took time for me to come back to my self and do some test instead
  9. on emmc U-Boot 2014.07 (Mar 14 2019 - 16:09:23) Allwinner Technology on sd card U-Boot 2019.01-armbian (Apr 11 2019 - 11:38:28 +0200) Allwinner Technology maybe u-boot works from emmc if present? i guess everyone who has reboot issue is using emmc boot ?
  10. i just downloaded https://dl.armbian.com/orangepi3/nightly/Armbian_5.78.190411_Orangepi3_Ubuntu_bionic_dev_5.0.7.7z and done same test and as I can see reboot also works without loosing eth0. ssh orangepi3 Welcome to ARMBIAN 5.78.190411 nightly Ubuntu 18.04.2 LTS 5.0.7-sunxi64 System load: 0.87 0.44 0.17 Up time: 2 min Memory usage: 5 % of 1997MB IP: 192.168.220.135 CPU temp: 39°C Usage of /: 2% of 58G Last login: Thu Apr 11 20:02:18 2019 from 192.168.220.1 root@orangepi3:~# logout Connection to orangepi3 closed.

  11. I am using lan to connect to opi3 and I cant see any problems with reboot and network after that, what is quite strange thing. compiled code with armbian build script docker option and booting from sd card. ssh orangepi3 Welcome to ARMBIAN 5.78 user-built Debian GNU/Linux 9 (stretch) 5.0.7-sunxi64 System load: 2.20 0.68 0.24 Up time: 0 min Memory usage: 12 % of 1997MB IP: 192.168.220.135 CPU temp: 41°C Usage of /: 4% of 30G Last login: Thu Apr 11 19:37:32 2019 from 192.168.220.1 while (sleep 60);do ssh orangepi3 'uptime;reboot';done 19:42:13 up 4 min, 0 users, load average: 1.05, 0.85, 0.39 Connection to orangepi3 closed by remote host. 19:42:46 up 0 min, 0 users, load average: 2.60, 0.66, 0.22 Connection to orangepi3 closed by remote host. 19:43:48 up 0 min, 0 users, load average: 2.29, 0.56, 0.19 Connection to orangepi3 closed by remote host. 19:44:39 up 0 min, 0 users, load average: 1.25, 0.29, 0.10 Connection to orangepi3 closed by remote host. 19:45:39 up 0 min, 0 users, load average: 2.11, 0.51, 0.17 Connection to orangepi3 closed by remote host.
  12. reboot works. opi3 with emmc booted from sd card. image which i used
  13. No, I use apkpure package manager. To much effort needs to be put in, to get google working
  14. I agree that it is quite good deal for a money. using android works great as media player (vp8,x265) and even some games works nice. I recommended everyone to try Beach Buggy Racing as gpu demo game is quite impressive. Linux is another story but it has bright side to
  15. ----------------------------------------------------Update-------------------------------------- changing code had no results, neither edid is present nor hdmi started to work as in BSP kernel. i change code while make menuconfig was waiting for input, and then just continued image as always. i agree that is is not best way to do this maybe there is easier way for the same ? as automated build pull code each time and changes branch to master ?
