  1. Still happy to send you a monitor if it would help.
  2. 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!)
  3. Yeah I was sure. Line 15 DDC. I also offered to donate a monitor.
  4. 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.
  5. Yeah there's something wrong with u-boot when it tries to read the edid info. Read more about it here...
  6. Try unplugging your hdmi cable and booting. Wait a bit to make sure it's fully booted then plug in the hdmi cable.
  7. 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.
  8. Lol! I'm going to load tinkeros and see if that works first.
  9. 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?
  10. 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.
  11. 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.
  12. Here's the full boot with CEC disconnected...
  13. Ok I switched to ttyS2 instead of ttyS3 and I get this at boot with CEC connected... (via picocom) U-Boot 2018.07-armbian (Sep 19 2018 - 13:23:29 +0200) Model: Tinker-RK3288 DRAM: 2 GiB MMC: dwmmc@ff0c0000: 1, dwmmc@ff0f0000: 0 Loading Environment from EXT4...

With CEC connected and monitor plugged after boot I can get up to 1920x1080 (even though the monitor supports up to 1920x1200.
  15. I can do that but I won't be back at the office till Monday.
