  1. Hello, everyone. I'm planning to make a "power button" on orange pi zero using GPIO pins. I'm using kernel 4.x Of course, some questions. General idea is: 1) Create the overlay with correct pin number 2) Install acpid 3) It should work. Questions: - What resistor should I use to short pin to ground ? 10K ? May other values work ? (Not sure my "scrap metal" box has exact this value) - How does overlay file look like ? I've seen some variants on the forum, but can some one point to working code ? I'm planning to use PA06 pin, as far as I understand it's a pin 7 on OpiZero 26 pin connector. - I'm already using overlay for I2C for I2C0 (pins 3 and 5). Do I understand correctly that introducing acpi button won't affect I2c functionality. Thanks a lot in advance

    @svts, u digged great thing. U told me, that boards were bought not from Xunlong shop, but from some third-party guys. Good thing for Xunlong -- their products are being copied =) with cheaper components (which is sooo aliexpress -typical). Bad things for most of us -- when you buy a board from a "local supplier" or cheaper than in official store, most probably you can bump into a "fake one". Because supplier cares about margin/income/whatever, not about the quality of product. Probably in Europe/US the situation is better, but in countries like Russia it's pretty typical. So time to say "beware of fake Orange Pi's " ?

    @svts see results here: https://pastebin.com/5CXyyuQm Script runned for approx. 10 minutes, giving message presented in the paste (I've added only last 3 minutes I guess because "screen" truncated it - hope it's enough) Also dmesg has swap/oom errors and I see docker container is restarting, but it was done during high load to ram/swap/cpu. Note to myself: invest into better microsd cards :).

    @Seasalt, thanks! I'm working on new version, with OpiOne+ (faster!! newer :)) and fitted into standard microATX case. Want something more standard and reproducible. @svts Hmm... You are right. I even upgraded whole bunch of board to latest armbian to check if it is an issue of latest builds. But looks like no. ~1 hour 100% load, no "mayday mayday" zno@cluster:~$ for i in `seq 0 9`; do ssh node$i uptime; done 10:47:44 up 1:02, 0 users, load average: 4.01, 4.03, 4.00 10:47:45 up 1:01, 0 users, load average: 4.08, 4.02, 4.01 10:47:46 up 1:01, 0 users, load average: 4.18, 4.06, 4.02 10:47:47 up 1:00, 0 users, load average: 4.00, 4.01, 4.00 10:47:48 up 1:00, 0 users, load average: 4.00, 4.00, 3.99 10:47:50 up 59 min, 0 users, load average: 4.02, 4.05, 4.00 10:47:51 up 59 min, 0 users, load average: 4.00, 4.00, 3.98 10:47:52 up 58 min, 0 users, load average: 4.16, 4.09, 4.02 10:47:54 up 58 min, 0 users, load average: 4.00, 4.05, 4.00 10:47:55 up 57 min, 0 users, load average: 4.00, 4.01, 4.00 Consider "yet another lame idea". Can you try to power stuff via GPIO pins, not via barrel connector ? I used 2 wires from standard Ethernet patch cord. Just as experiment.

    @svts Here is dmesg from 2 nodes. One bought long time ago: https://pastebin.com/Q0As9JTh And second from node which was recently replaced due to dead Ethernet (still not sure, that I picked right node, but anyway -- 2 dmesgs better than one): https://pastebin.com/8s91VAuU Hope it will help you. I still have a strong feeling, that the problem is inside hardware (RAM). May be it makes sense to order new one from official store@Aliexpres ? Just to be sure. I can bet, it will arrive faster, than you will debug the thing...

    @Seasalt, not sure I've got the question "What is your cluster" -- link I posted do have some pics and there is a "translate" button in menu (better than nothing). About cluster purpose -- currently it it mining some Verium crypto. Before I tried Apache Spark, for example. But not really successfull due to faulty microSDs and large number of read/write. Regarding benchmark - in mining (hashrate) it is comparable to e.g. core i5..i7, but well -- it consumes much less energy. E.g. 60..70 watts vs 150..200. I was inspired by this guy http://picocluster.com -- but my setup is much more cool :)). I'm using custom PCB to drive ATX PSU and fans.

    I think I have 1.1 And I use Armbian only, no other distros. It just works :). I've even disabled updates since everything looks pretty stable. My cluster : http://znoxx.me/2018/11/08/table-cluster/ :)

    Here is my Uboot version info and I don't see _any_ troubles. My armbian "cluster" works 24x7 with full load. zno@node0:~$ uptime 13:49:53 up 1 day, 7:44, 1 user, load average: 4.21, 4.07, 4.03 zno@node0:~$ dpkg -l | grep Uboot ii linux-u-boot-orangepipc2-next 5.40 arm64 Uboot loader 2017.11 Only one lame assumption. May be "other" version of u-boot clocks memory to lower values and it is working stable ? Or may be your hw is broken somehow ? For example, I have one OpiPC2 which has dead Ethernet. By the way, my boards are running at freq=1104000 (watts saved amount is bigger, than performance drop).

    Hi all Is there any way to increase CPU speed ? Currently armbianmonitor gives me 1152 mhz, but cpu itself can do more, I guess...

    Looks like stability issue. Start with PSU and microSD replacing.

    ARDUINO IDE on ORANGE PI PC2

    I think you need Java to run it and Java is available for arm64 Try those steps http://www.instructables.com/id/Installing-Using-Arduino-IDE-on-a-Raspberry-Pi-3/ - may be it will work

    Actually I run snapsot from 17 nov and it is working. I even see difference with different thermal compound in different boards.

    Just achieved 192 hash rate vs previous 147 on opi pc2 with updated miner and hugetables kernel option. Thanks, people! Do not remove hugetables support from kernel

    There is an awesome tool "h3consumption" for allwinner h3 boards. E.g. I disables unneeded USB interfaces and my diy cluster is consuming less Is there anything similiar for H5 ? E.g. how I can disable USB and force Ethernet to 100mbit ? Thanks in advance for your answer.
  15. Igor, thanks! No rush at all, my goal is to follow "usual update", not to try something special, since my cubie is acting like a server in, well, production mode. Please take your time :). Currently it's working and the last thing I want - visiting the location where it placed and connecting HDMI in case of failure Thanks in advance for your efforts.
