GND is actually pin 4 of a USB connector. The numbering is also not reversed cause then D+ and D- wouldn't be correct anymore. So that's just wrong in the schematics.

So, it should be the same as mine : Ok ! The block diagram is wrong, but I never care about block diagram, I care only about real schematic ... Page 8 clearly states that VCC-5V is direct from DC-IN !
Not only the block diagram is wrong but the Power Tree aswell (which is somewhat important). And Page 10 clearly says that the VCC-5V is connected to the GND Pin of the USB, which is also not correct..... I don't really trust these schematics anymore....

Just tried this aswell, and indeed it's a lot better. Weird.....
Anyways, there doesn't seem to be some kind of regulator involved so it's all good now!

Are you looking at the wrong schematic ?
OrangePi3 != OrangePi-RK3399 !!!
Nope, it clearly says Orange_PI-3 on it, downloaded from the Google Drive. Dated at November 26th 2018.

The schematic is clearly stating that USB 5V is coming from VDP3/VDP4 which are connected to VCC-5V, therefore directly from DC-IN of the board
The schematic also states that VCC-5V is connected to GND of the USB Connector, thats also not the case here so I am very careful about believing that.
Also in the powertree and the Block diagram it has a 12V in connected to a DC/DC Converter. Looking at DCIN that DC/DC regulator is gone. So I am really careful when it comes to reading this schematics....

Could anyone else check the voltage on USB please? I'm seeing very low voltages of 4.5V idle to 4V maxed out.
I'm using a OPi cable and my 4A PSU from my NanoPi M4. I would like to know if it's my setup. Thank you.
P.S.
With a higher input voltage of 5.3V(vs 5.1V) I get 4.75V idle and 4.5V maxed out.It's indeed a little low on mine aswell, using the manufacturer's OS it is higher. I think there is just something set wrong on a voltage regulator? The schematics also seem a little off when it comes to the USB Port: GND is connected to the VCC Pin of the Port and vice versa. I was looking for a voltage regulator there but other than the AXP805 I didn't find one. I looked at the AXP805 Datasheet to see if it could be this one, but as it can't output 5V this can't be it. This leaves 2 options: Either it's connected directly to the 5V Input, so does the armbian OS use that much more power than the manufacturer's OS? Or there is indeed some regulator or protection that is not configured properly at this point.

Logout and Login again was indeed the solution. Thanks!

I'm at 5 right now (and not at all new) but still can't post. So maybe even more posts are required?
Also that should definitely be documented somewhere (or somewhere more obvious since I searched for that and couldn't find anything about some kind of restrictions). Maybe like a sticky post in that section like "In order to post here you need to do xyz"
Edit: 6 is also not enough.....

I am not aware of such a function and Igor just did a post in there.
I can't post in there and also I can't access the contact page to contact someone to ask whats wrong. I just tried to change my E-Mail Address to the same E-Mail Address to re-do the verification, but still no luck. @Igor Could you help me out here please?

the guys over here trying to get the best out of this board
https://forum.armbian.com/topic/9368-orangepi-3-h6-allwiner-chip/
Is it somehow restricted who can post in that section? I found an issue (USB Voltage regulator doesn't seem to be set properly, works with the manufacturer image though) and someone in there asked a while ago if he's the only one with the issue, I wanted to respond but can't post in there.

Looks more like wrong password entered to me as it doesn't even ask for a new password.

Can that library be used even though it's for h3 and orange pi uses h5?

Is someone able to provide Information about the GPIO Interface? There is zero documentation about it on the Orange Pi PC2. How are the port numbers calculated, how are internal pullups activated? As someone has implemented the gpio stuff, it should be usable, I just haven't figured out how to talk to it.

Unfortunately I am suffering from stability issues in this (unstable) build aswell. I am booting from a USB HDD and I have connected the entire thing to a 5V 3A power supply that also really delivers the 3A (actually verified that). Also it's slightly above 5V at the Micro USB Plug so I think the power should be enough. Could this be related to the issue mentioned on the page before (increased voltage to the CPU)? How are chances that 5.4 kernel will be more stable for me? Is there anything I can do now to make it more reliable or at least to have it automatically reboot? I have set panic=1 already but that doesn't help, maybe the watchdog can be enabled as a workaround for now somehow?
