I checked graphs "active cooler (ODROID-XU4) VS passive cooler (ODROID-XU4Q)" on www.hardkernel.com. You are right @TonyMac32, it is in couple of seconds before SoC temperature starts hitting a roof, not miliseconds. Because there is still little possibility the heatsing is not attached right (hardkernel's decided to put SoC not to the middle of heatsink), it is not clear is this software or hardware issue.

And what about if this temperature spike above this limit is reached for couple of ms during heavy load? What could I test is better cooling block/heatsink with better absorption capability but I have no idea where can I get better one. I made USB to 3pin fan adapter with inserted step up converter boosting 5V to 12V. And has started testing again.

Maybe it's incorrect but it shutdowns board anyway. Secondly why only one board having this issues even system is cloned and these are connected to same power rail ( rated 5V 10A ) .

Hi, I received 2 same boards recently. One is working great, second has suffered from unexpected shutdowns. Rpimonitor has not recorded this high temperatures yet, maximum temperature recorded is not more than 90C. SoC has been utilized on 100% with ffmpeg video conversion and other tasks. I run these board on Jessie or Bionic system and have tested mainline stable and beta kernel. These board have got passive heatsink however I put 80x80 quiet slower fan on the top of heatsink, thermal compound is replaced for silver one without making problem solved.

What is strange that script reports if dc in is NOT present: Battery discharge current = 0mA Battery charge current = XXXmA Secondly BOINC manager do not register system is running on battery.

I checked the datasheet and not register 0x34 but 0x33 is responsible for charging current. However it has been already set to maximum value 1200mAh. To get status of register I run command i2cget -y -f 0 0x34 0x33. Because the value 1001 for bit 0-3 has been reported back, there was nothing to adjust to get higher charging current. binary 1001 => decimal 9, 9*100mAh + 300mAh=1200mAh I found useful script, see link below, reporting charging values and status of both registers 0x33 and 0x34 (default values: 0xCX and 0x45). https://gist.github.com/tstellanova/b726545cc9bd2a01bb553f34509a5c96

I have got Lime connected on big battery pack. Therefore charging takes long time. Do you have an idea how to increase charging current on 4.X kernel ?

Very good effort mate, I followed your instructions and successfully changed OTG port to host mode on my A20 lime board. It was really necessary for me because this board has got only 2 USB ports. Just only for record I did it on kernel version 4.14.15-sunxi and it was really hard to find complete instructions.

It would be nice to get working a second ESP8266 with a display connected to and redirect temperature and humidity data to this.

Do you want to support so overpriced product? Board you bought for about £60 should be selling for £20 with software support you can get now.

Version ? 5.27 build from sources on about 3rd of April.

I have sorted out nfs booting problem differently using older image couple of weeks ago. But I had same screen on my Orange Pi 2 mini when I watched booting on serial console. I changed settings in /boot/boot.cmd to "console=ttyS0,115200" (without quotes) from "console=tty1" and it solved problem when booting stopped on "ion_reserve_common ... Probably booting did not stopped like I thought. Probably just only output of serial console was silent.

@tkaiser I tested 10pcs of 128MB sized and there is result. I needed insert card in and just only press enter in opened terminal screen (with command ready like badblocks -wsv /dev/mmcblk0), replace card and press again until no more cards left. Badblocks found 5 cards with errors and i decided just for case test good ones with f3. I must mount card, change directory, write test data, unmount, unplug it, plug it again. (I tried test on cards marked bad by badblocks and sometimes it did not find error without replugging it !!!) and make same procedure .. mount card, change directory and run reading test of previously data. And result of f3 test on "badblocks" cards marked ok? F3 did not find any error. Sorry F3 is not user friendly and I am definitely staying with "badblocks -wsv" which is easier to operate for me.

I run test on debian distro at this moment. (I can switch on windows but only if it is question of life or die). Thank you for keeping me updated I gonna try f3.

I needed small sized cards for nfs boot. I ordered 10pcs of them on Aliexpress and received exactly same ones (Nokia 128MB) probably ripped off old phones :-). 1 could not initialize but rest of them passed badblock test (I received refund for bad piece without any problem). Than I ordered cheaper ones, 10 pcs again. I got new cards with orange/white colour. 1 could not innitialize => rubbish 2 did not pass test in external but passed test in internal reader => ??rubbish 2 did not pass neither in external or internal reader => rubbish So keep this card :-) it still has value.

Another question which can help me to build working system. What should I change to build previous release of system? For example latest release is 5.27 and I want 5.26...

Hi guys, do you have idea why boot stopped? Check log below please. It was build about 25minutes ago but about 1 week younger build was working.

This is second afternoon I spend trying configure wifi on headless orange pi because we started using nmtui-connect (editing /etc/network/interfaces was much more easier especially when I need make universal image for about 15 same boards). It found wifi but when I try enter password it instead shows message "Could not activate connection: No plugin │ │ │ │ supported adding this connection" I can select which wifi I want but It everytime ends with same message. I tried it on image Armbian_5.25_Orangepizero_Debian_jessie_default_3.4.113.img I made no changes on this image except changing root password. User creation I canceled.

Thank you for your help @zador.blood.stained This case is closed for me ;-).

Look I watched building process and it needed about 52% of 3000MB tmpfs. So if you want change value 1500 to 2000 it will be ok if you want keep checking BUILD_DESKTOP variable.

yes good idea Nope, it is 1.5GB with 8GB or 16GB of system RAM configuration on my Virtualbox machine. I cut one line from "debootstrap-ng.sh" for you: if [[ $BUILD_DESKTOP == yes ]]; then local tmpfs_max_size=2500; else local tmpfs_max_size=1500; fi # MiB I changed both values to 3000 in Virtualbox machine with 16GB RAM and trying another building round.

I have problem with low space during building orange pi zero image ( even there free space about 50GB on both root and secondary drive ). I happens at the end of image creating when batch customize-image.sh started. Do you know where is variable responsible for 1.5GB big /armbian/output/cache/ ? Thanks.

This nas expansion is great idea when ssd drive lifetime and performance is much better than sd card. If it will be released with proper plastic case I will buy it. (performance bottleneck of usb sata converter I am leaving without comment. This is cheap device area and I do not expect this item flying for this price.) Sent from my Redmi Note 2 using Tapatalk

Hi vincele, it is good idea. If you can make script which download latest source and make deb it will be perfect. I do not know if there are new version coming but it is better for future than some static stuff.

Hi @rsegoly again, I tried link you posted. Archive in the link you provided contains driver for rtl8192cu but it seems to be original one from Realtek not always working. Try this patched driver instalation procedure instead: cd /usr/src git clone https://github.com/pvaret/rtl8192cu-fixes.git cd rtl8192cu-fixes cp -v blacklist-native-rtl8192.conf /etc/modprobe.d cp -v 8192cu-disable-power-management.conf /etc/modprobe.d make -j4 make install
