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.
-
Although this may have been patched at some point (because the problem seems to have went away) it appears to be back again.
-
Still happy to send you a monitor if it would help.
-
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!)

I agree, however we weren't clear which wire was even cut last time we discussed, so I can't be sure what feature is truly causing the issue without confirmation. I unfortunately don't have a monitor that causes this, I'll run through them again and see if I can find one I guess.

Yeah I was sure. Line 15 DDC.
I also offered to donate a monitor.

We added some patches from Asus to enable some of the nicer things like CEC/etc, unfortunately someone with a similar problem apparently simply decided to start cutting wires instead of finishing the software debug. Have you tried another monitor that may have different/more limited capabilities?
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.

Wow, have not tried. I'll try next monday. Thanks !!
Yeah there's something wrong with u-boot when it tries to read the edid info.
Read more about it here...

Try unplugging your hdmi cable and booting. Wait a bit to make sure it's fully booted then plug in the hdmi cable.
-
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.
-
Lol! I'm going to load tinkeros and see if that works first.
-
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?

I only adjust console with reality. I don't care where it will be, but it would be nice that we have it at one location on both kernels.Rather wait. You might go in the wrong direction. Work smart not fast. Try older bootloader first: http://apt.armbian.com/pool/main/l/linux-u-boot-tinkerboard-next/ This is the first and most cheap possible solution.
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.
-
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.

Here's the full boot with CEC disconnected...

(testing finished)
I should note that with the CEC wire disconnected only two resolutions are available - 800x600 and 1024x768.
With CEC connected and monitor plugged after boot I can get up to 1920x1080 (even though the monitor supports up to 1920x1200.
-
I can do that but I won't be back at the office till Monday.
-
Who do I report this problem to? Looks like a bug to me. Who creates the kernel that armbian uses?
-
Does anyone know why kernel options don't save in armbian-config? I've set hdmi_ignore_cec=1 but changes always disappear upon reboot. Not that I know that would fix it but there's a number of hdmi options I thought I would try.
-
...in the meantime I'm going to walk around with cutters and clip the red wire on all my terminals. Lol!

2 hours ago, Myy said:
Logging through the serial console is configured through systemd and boot parameters... But, yeah, one of the default behaviour is to output the kernel messages through the serial console ONLY IF no screen is available.
So I guess that HDMI CEC support is broken ? Does the freeze happen with other screens too ?
The default UART for debugging purposes on RK3288 is the UART2 (/dev/ttyS1). It might be changed though. The RK3288 Datasheet name UART2 "uart2dbg". UART3 is for plugging GPS systems (which is not used very often, I concur).
Just for information :
1. When the HDMI cable is plugged, do you have any SSH access ? If you wait for 5 minutes, is it still frozen ?
2. If you start without an HDMI cable, get a serial console and *then* plug the HDMI screen, what happens ? Do you have any crash or freeze message ?
I remember some bug a long time ago, about 4.14 kernels... That would make the system unbootable if you plugged the HDMI cable before booting :
https://github.com/Miouyouyou/RockMyy-Build/issues/1
I don't remember how I was able to get a log for this though...
1. No ssh access. Left it sit for an hour or more.
2. My guess is it works but I just messed up my test environment. I'll have to redo everything next week. Today's my last day till Monday.
-
Here's a cool update... I took an extra hdmi cable I had lying around and cut what I believe to be the CEC line and the system boots fine.
-
Like I said the startup is visible if the hdmi cable is disconnected.
-
I'm connected at UART3.

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?
