  1. My Power Supply has a micro usb plug attached, so if I want to use the dc jack I would have to remove that one first Every connector adds additional resistance so I try to avoid it whenever it's possible.
  2. I think this board has quite some issues though, even when I go in with 5V on the Micro USB it's not enough to power a HDD on the USB Ports (and I'm not the only one with that issue), so I was wondering if this might be another issue this board has.... I guess I need a 5.5V Power Supply to account for whatever losses happen on the board. Is it better to go in through the DC Jack? I read about issues with that some time ago aswell and as I would have to cut my USB Cable I want to be absolutely sure that it's better before I try it.
  3. As you can read (some posts) above I am using 2 Power supplies and the voltage should be stable at the board. I'll try to run a stresstest though once I rebooted the board to see if that could be the issue. Just to confirm: For you this board is running stable?
  4. Unfortunately my Orange Pi 3 is still very unstable, even with the latest version. I get a maximum uptime of 4 days, and sometimes like now it won't even reboot automatically when it crashes. I'll try to see if it's possible to setup kdump tomorrow to see if this is caused by a panic (and what causes it) or the CPU simply goes into reset. I am running Armbian from a USB Drive, I need to check if maybe USB initialization fails and that causes the reboot to fail. Has anybody else experienced something like this?
  5. The air should be moving upwards by itself but anyways, now that I know that this is a known problem I prepared a 40mm fan with a USB plug that I can just mount on my enclosure and it will blow straight onto the heatsink. That should be enough cooling to keep it under 80°C. Another thing I noticed: I have a 5.2V 3A Power supply connected to the Micro USB connector. On the USB3 Ports I have a HDD connected and that HDD just gets 4.7V, so either some rails are a little too thin on the board or the Micro USB connector adds quite some resistance. Has someone seen that before? Is it better to use the DC Jack than the Micro USB connector? At the moment I used a second power supply with an USB-A/USB-A cable to provide additional power to the USB Port but that's obviously not a good solution (but it works at the moment).
  6. 1.6 is not low enough to keep it under 80°C, 1.32 keeps it barely on or below 80°C, that's not with all cores completely used though, I'm at about 50% on 3 cores and 90% on one core.
  7. Is anybody else seeing the issue that the CPU is constantly at around 80°C causing the CPU to be throttled down to 1.08Ghz maximum speed? I added a heatsink to the H6 CPU and switched the governor to conservative but that didn't really help.
  8. Unfortunately my SD cards are for some reason wearing out extremely fast, so I prefer other methods. Also my CPU temperature is constantly around 80-85°C. My board is one of the first ones by the way. Bought shortly after they launched it. The new kernel seems to have broken CPU frequency scaling, it's running now on 0Mhz according to htop and the CPU is on the limit..... # cpufreq-info -ecpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009Report errors and bugs to cpufreq@vger.kernel.org, please.analyzing CPU 0: no or unknown cpufreq driver is active on this CPU maximum transition latency: 4294.55 ms.analyzing CPU 1: no or unknown cpufreq driver is active on this CPU maximum transition latency: 4294.55 ms.analyzing CPU 2: no or unknown cpufreq driver is active on this CPU maximum transition latency: 4294.55 ms.analyzing CPU 3: no or unknown cpufreq driver is active on this CPU maximum transition latency: 4294.55 ms.
  9. In order to solve my issues with the lockup I tried to enable the watchdog but I found the board locked up again this morning. Either the reboot is not working cleanly or the watchdog is not resetting the board correctly or my USB HDD is not initialized properly. I upgraded to the new kernel now (5.4) and hope that it's more stable with this one. I'll report back on the next lockup. As I'm facing those lockups on an almost daily basis I thought about adding a timer to the power supply that cuts the power once per day to do a clean restart. That would definitely work but if there are other ways to make it more stable I'd prefer those. I'm running munin on the device aswell but couldn't find anything that happend right before all of the crashes, CPU utilization and frequency was below maximum, there was still enough RAM so absolutely no indication of any issue.
  10. 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?
  11. 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.
  12. 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!
  13. Nope, it clearly says Orange_PI-3 on it, downloaded from the Google Drive. Dated at November 26th 2018.
  14. 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....
  15. 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.
