  1. Using Linux tinkerboard 4.19.69-rockchip #5.95 SMP PREEMPT Mon Sep 2 07:34:36 CEST 2019 armv7l armv7l armv7l GNU/Linux Using glxgears as a test case.. I get 60fps without the screen rotated. If I rotate the screen right or left the frame rate drops to 4fps. That's on a fresh boot with nothing else running. I tested TinkerOS on the same board and it works fine rotated. My Raspberry PI 4 works fine rotated as well. What could be the problem with Armbian?
  2. Network Manager is garbage. We had to uninstall it and go with wpa_supplicant on our 90+ tinker boards that we have deployed. Constant disconnects with Network Manager and wpa_supplicant works all the time.
  3. Although this may have been patched at some point (because the problem seems to have went away) it appears to be back again.
  4. Still happy to send you a monitor if it would help.
  5. I should also add that I don't EXPECT anyone to fix this. That's why after I was told to debug u-boot I stopped talking about it. We stopped updating the units for now while we weigh out our options. (but I do appreciated any effort anyone puts into it!)
  6. Yeah I was sure. Line 15 DDC. I also offered to donate a monitor.
  7. Cutting the wire is what helped me find the problem. Finishing (or even starting) the software debug of u-boot is probably out of reach of most users.
  8. Yeah there's something wrong with u-boot when it tries to read the edid info. Read more about it here...
  9. Try unplugging your hdmi cable and booting. Wait a bit to make sure it's fully booted then plug in the hdmi cable.
  10. Well you can't expect your end users to become u-boot hackers just to keep their systems running. I realize you can't do everything for everyone and that's the dilemma that open source projects always face.
  11. Lol! I'm going to load tinkeros and see if that works first.
  12. Maybe... I just wanted to make sure. Any tips or links for help on how to replace the bootloader? edit - I figured it out. Boots now. What's the best course of action now?
  13. I think you misunderstand what I am saying. I thought I cut line 13 which is CEC. Turns out I cut line 15 which is DDC.
  14. Ok... a co-worker with better eyes than me says I cut pin 15 on the hdmi cable not 13. If that's right that's DDC? Not sure what the implications are of that. I ordered an hdmi cable tester which should be here tomorrow.
