  1. Hi. Support has ended for this board. These images seem to be old images. If possible you could try building a more recent image. You do need an x86 machine for this.
  2. Do you know the HDMI-in functions under Linux? Banana Pi people never give straight answers. I don't want to buy it to hang on my wall as most useless trophy. Nice list
  3. That makes me think about the fact I also bought a Tinker Board for a friend with 7" display and rii i8 mini keyboard. I guess it has never been used, since he never asked how to do anything with it. That's 3 of those horrible Tinker Boards I wasted my money on, and they're so expensive... And also a rpi3B for my nephew with RetroPie installed and 128GB of games. No need to say he loved it. Until he got a Playstation(I don't know which number).
  4. I'll for sure forget some of them. It all started with the Raspberry Pi2B(4 years ago now) ... and then ... Odroid C2 (For 3 years my favorite. Clocked at 1.75Ghz, with 128Ghz eMMC and ram OC it's amazingly fast. Low power consumption, good video playback(low display resolution), great gaming on it. Still use it as my SBC laptop, but the VIM3'll replace it Raspberry Pi3B (Not better than the pervious model. Dissapointed by it) Raspberry Pi Zero (+ 2 x Zero W) (was handy, had build a Pi0Camera with it and an audio recorder, got in dissuse) Orange Pi+2 (hated it, I still believed the 1.6Ghz bs, afterwards started to love it for what it is) Tinker Board (x2) (Worst buy ever, too expensive for what it's. First broke, I was so stupid to buy another one without using it much) Khadas VIM2 Max (Too slow for what it is. Otherwise a good designed board when used for what it's good) Odroid XU4 (Loved it. It was my 2nd desktop with a HDMI-hub so I could switch to it when my PC was bussy. Amazing performance and great games. But a lot of issue's too) Rock64 (a lot of issue's, nice on paper but doesn't deliver it's promises) Banana Pi M2 Zero (nice little board, runs too hot to be useful, but had a lot of fun with it) NanoPC T3+ (Love it a lot. Amazing for Blender renders, at a low power consumption. But single core performance is too low, should be default overclocked to 1.6Ghz in my opinion. It can handle it and cooling solution is sufficient) Raspberry Pi 3B+ (What a garbage board. DDR2 with a ok SoC is a bad combination. Bad power delivery, not very useable) NanoPi M4 (My favorite until the VIM3 came, all-round a great board. Too bad there's a lack of Linux drivers for great gaming on it) Rock Pi 4B (First impression was great. But that went away after a while. Many software issues. I hate that I can't reach my eMMC with the big heatsink on) NanoPi DUO2 (Still need to review it, but my first impression wasn't too good. Bad thermals, no hardware video encoding for the camera. This should be fixed by now, maybe a next video someday...) Orange Pi 3 (Ok SoC, badly designed board) Pine H64 model b (Ok SoC better designed board, it's their second try tho) Odroid N2 (Great board, amazing performance and no fan needed. But runs at 12V so I can't run it on my power banks. I use it headless with VNC to do render jobs together with the NanoPC T3+) Nitrogen8M Mini (I don't know yet, no HDMI and all proprietary connectors for everything. It is an industrial board for KIOSK's, but I'd like to see HDMI to set it up easily. It does have great audio assets, amplifier, audio in-out) Khadas VIM3 (My newest favorite. What a performance for such low consumption at 5V. I've got the Basic, so much want the Pro... It's perfect to take with me to do heavy video render tasks. I love it...) Raspberry Pi4B (My biggest surprise ever. Not thinking too much of it. But it's a lot more than I thought. Performs amazing. But still has its faults. I think that's it. In chronological order I bought them. The first 2 were great boards that I still use a lot. But then I bought a lot of them that never delivered what they promissed. Only the XU4 and NanoPC T3+ were great. I started to get them for free to review starting with the NanoPi M4, and those were again very good. Only bought the Odroid N2 after that. Good I review SBC's, I'm saving myself a lot of money now I've spend enough in the past on them. Cheers
  5. Here my view on the Raspberry 4b. It's a high performance board, unmatched by any other qua-core. But with some issue's. Undevoltage still there with non RPi PSU's. sd-card is now the biggest bottleneck of it all. Tho it has doubled in speed to 40read and 20write. That's not enough for a powerful system as this. It's no more a pure IoT board, but more a cross-over to pc. Plenty of power, dual HDMI. Up to 4GB lpddr4 ram. Here my video about it. And here some of my test results. Raspberry Pi4B -------------- Raspbian Buster --------------- Blender results Default clock 1.5Ghz No fan Tinker heatsink : 1h57m23s 3v fan Tinker heatsink : 1h29m07s OC clock 1.75Ghz 3V fan : 1h19m25s 1.85Ghz 3V fan : 1h14m05s 2.00Ghz 3V fan : 1h10m24s 2.00Ghz 3V fan : 1h09m39s gpu_freq=600 sbc-bench Ubuntu arm64 ------------ default clock 3v fan Tinker heatsink : 1h21m05s 1.75Ghz 3v fan : 1h08m42s 2Ghz 3v fan : 1h00m12s sbc-bench Temperatures ------------ Big Tinker heatsink no fan idle : 58°C maxed out : 83°C heavy throttle to 1000Mhz after about 3 minutes 3V fan idle : 37°C maxed out : 50°C OC 1.75Ghz 3V fan maxed : 55°C OC 1.85Ghz 3V fan maxed : 57°C Power consumption ----------------- Default idle no wifi : 0.64A Default idle with wifi : 0.7A Default maxed : 1.3A 2Ghz over voltage 4 GPU 600Mhz idle : 0.8A maxed : 1.85A (2A with fan) Issues ------ Governor again shows falls frequency numbers. vcgencmd measure_clock arm <- show the real ferquency Undervoltage problem is still there.

  6. Isn't there a simular SoC with HDMI-in? I thought I red somewere this was the cheaper version of that SoC. Here-> A small, cheap SBC with HDMI-in and Linux support for encoding it. That I'd buy and many of my viewers. Then I wouldn't mind having 100Mbit/s ethernet and USB2. Having an SBC for this would make life easier compared to the HDMI-capture box I'm using now. I never know what it is recording until I see it afterwards. The W2 looks great, but it's too expensive not knowing if it'll work well for my goal. Keep on making great stuff. I love all SBC's. Greetings.

    Review : Khadas VIM3

    @lanefu Sorry, I forgot to share my benchmark file. I did find out that 7-zip multicore results are not to be trusted on SBC's with different cluster performance. The VIM3 has a very big difference so it only uses 500% of 600%. The N2 has a smaller difference in performance between A73/A53 so uses 550% in 7-zip multicore scores. (also lack of memory is a problem) CPU Miner is good, 7zip single core benchmarks are good. And for me Blender is important too. Reasons why benchmarks can be misleading ---------------------------------------- throttling 32-bit/64-bit Difference in cores A53/A7/A15/A72 distro (ubuntu/debian...) distro version kernel version driver versions compiler version software version/outdated repositories desktop Mate/Xfce/LXDE/... display resolution/headless background processes cpu clockspeed ram clockspeed/latency ram useage/swap/zram process sheduler optimizations for the system/distro crypto engine for encryption Undervoltage config settings Wifi dongle CONFIG_HZ=250 - 1000 or any other 7-zip works a bit better on 32-bit vs 64-bit, it doesn't use all cores at 100% in multi-core scores. The percentage differs with different distro's and boards. So it's not completely exact. 7-zip has problems with big-LITTLE architecture for multi-core benchmark. Better to test the clusters seperately. Blender works a lot better on 64-bit than on 32-bit. It uses 100% of the cores. CPU Miner only works on 64-bit. Works better in Ubuntu Bionic than in Debian Stretch. Blender : BMW render @ 1080p 7-zip : Numbers are average of 3 of decompressing only All tests are done with a fan when necessary so no throttling occurs. 64-bit SBC's Khadas VIM3 |SBC bench result

  8. Hi all. I've just finished reviewing the Khadas VIM3. It's an amazing SBC with unmatched performance. It's got the Amlogic A311D SoC. Comparable with the S922X of the Odroid N2. But the 4x A73 cores are clocked at 2.2Ghz and the 2 x A53 cores to 1.8Ghz. So it performs a lot better. It also comes with an NPU, MIPI-DSI and MIPI-CSI. And can be powered with USB type-c from 5V up to 20V. Here my review video. Here all my gathered information. Khadas VIM3 ----------- Ubuntu server - fan over fins ----------------------------- Blender BMW no fan thermal pad : 59m with copper shim : 58m18s with 5V fan : 45m01s with 5V fan over CPU : 43m28s Ubuntu XFCE - fan over CPU, not over fins ----------------------------------------- Blender no fan : 55m22s Blender 3V fan : 43m03s Blender 5V fan : 42m51s Blender with fan : 48m45s Armbian Bionic Small cores @1.9Ghz Big cores @1.7Ghz Blender with fan : 46m29s Armbian Disco Small cores @1.9Ghz Big cores @1.7Ghz Blender with fan : 46m56s Armbian Buster Small cores @1.9Ghz Big cores @1.7Ghz Kdenlive 16m bench 3V lxde : 1h09m (using 1GB zram + 4GB swap file. Not enough ram with 2GB) Video playback -------------- Ubuntu ------ Up to 4K 30fps with MPV. Very slight screen tearing. Anything lower is perfect Youtube playback with Firefox up to 1440p 30fps perfect KODI doesn't work (yet) No VPU acceleration for now. All done by CPU. LibreElec --------- Up to 4K 30fps with MPV. Very slight screen tearing. Anything lower is perfect Wifi doesn't work. power consumption ----------------- Idle no fan : 0.27A 5V (governor set to interactive) Maxed out with fan : 1.4A 5V (fan is 0.15A) Temperatures (fan over CPU, not over fins) ------------------------------------------ Idle No fan : 44°C Maxed out No fan : 75°C heavy throttling. 1Ghz small cores / 1.8Ghz big cores Idle 3V fan : 34°C Maxed out 3V fan : 73°C very light throttle.

Android : Can't connect wifi. I can type wifi password, but can't go further. No connect button. Tips ---- Use interactive governor for better thermals and power consumption with low use/idle. Plus/Minus ---------- + Best single core performance + best multi-core performance for an ARM SBC + Nice case + PSU + USB-c cable included + remote + eMMC + Amazing low power consumption / best performance per watt + Can be powered with 5V up to 20V + NPU - Wifi issue with USB3/No 5Ghz wifi. Could have solved the USB3 interference - Placing of the buttons would be better on the back. They often get pressed when plugging a USB device. You do get used to it. - No VPU and X11 drivers (yet) - Slow On-board SD-card reader Greetings, NicoD
  9. Hi @Nora Lee Very weird choice of board to call the BPi M4. I don't have the M3, but isn't the M3 a lot more powerful and more feature rich? Could you explain more about why Sinovoip chooses this as successor? I don't really understand it. 100Mbps ethernet(while using a realtek SoC), all USB2, no SATA, ... I don't know why or who this board is for. I would liked to have seen it with HDMI-in. Many people would want a cheaper SBC with HDMI-in. What will the price be? When is it available? I'm always willing to review it. Greetings.
  10. I tried it on the VIM3. Sound works. Great job.
  11. Great news. I'll try it out on a few boards. Amazing list of updates. I'm very happy with 88x2bu driver. Thank you for that. The change to lightdm is also something I can encourage. 1.8Ghz is the more sensible clock for the M4. I've used it to render my videos when traveling last month. 1.8Ghz performs a lot better per watt. Saving 0.5A for only 200Mhz loss(1.5A vs 2A). I also set my lowest clock to 400Mhz vs 600Mhz default, it saved a nice bit too on the idle consumption(0.35A vs 0.5A). I hope 2Ghz is still available. I'm now working with the Khadas VIM3. I think it was the last trip for the M4. The VIM3 blows it away in everything. Cheers all.
  12. You're a beast. Great work, I'll try it now. Thanks so much.
  13. Hi. You could try an old image to see if it also has this problem. It does look very strange.
  14. That's ok. It's the same, but a bit different configuration. It's 2GB zram. If it works, then let it. Unless you don't want zram. Then you can delete it.
  15. It's just : sudo apt install zram-config
  16. Hi. Maybe you could try to remove and reinstall zram-config. Open another terminal ALT-Fx sudo apt remove zram-config. Reboot and reinstall it. I have no clue why this happened. Please also provide the output of armbianmonitor -u if possible.
  17. Hi all. For my next camping trip I've bought a big USB3 2.4G/5G wifi antenna with the rtl88x2bu chip to have better camping wifi reception. It didn't work out of the box in Armbian. I've installed it on all my images manually. Question is if this driver can be baked into Armbian? It would save me a lot of work. And maybe many others too? For others who need this driver: Go to : sudo armbian-config -> software -> install headers Download the zip file : Unzip You'll also need to install dkms : sudo apt install dkms Then follow the instructions in the readme file in the rtl88... folder cd rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959 VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf) sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER} sudo dkms add -m rtl88x2bu -v ${VER} sudo dkms build -m rtl88x2bu -v ${VER} sudo dkms install -m rtl88x2bu -v ${VER} sudo modprobe 88x2bu
  18. Hi all. I've done a lot of tests with different desktop environments on Armbian. I wanted an as light as possible desktop environment so I'd have enough ram left to do video rendering with the NanoPi M4(2GB) I had to try a lot of things to get things working fine. So I wanted to save others that hassle. Setting up Display Manager First we need a Display Manager. NODM is installed by default. I tried lightdm but couldn't get it to work. So I went for LXDM. With NODM installed I had problems, so I also removed NODM. To be sure lxdm is configured right, I also manually configure it. sudo apt install lxdm sudo apt remove nodm sudo dpkg-reconfigure lxdm Install LXDE Desktop Next step is to install the desktop environment you want. There is a problem with some Desktop Environments and LXDM what makes you can't login to some DE's out of the box. That we will resolve later. Easiest is to install lxdm first to be able to configure the others well. And reboot. sudo apt install lxde sudo reboot Once booted you should be greeted by the Login screen. Here you can choose your different Desktop Environment. Choose LXDE and login. If you'd try xfce4, then you'd see it doesn't work. To fix this we need to change the file /usr/share/xsessions/xfce.desktop. Use your favorite text editor. I use geany. sudo geany /usr/share/xsessions/xfce.desktop Somewhere at the top of the file you'll see "Name=Xfce Session". Replace that space with a hyphen to "Name=Xfce-Session" and save the file. Now you can also login to the default XFCE4 Desktop. With other desktops this can be the same. Go the the same directory and open the file with the desktop name that doesn't work. Again replace the space with a hyphen Installing different Desktop Environments. For the Mate desktop I also needed to install the applets, else I got errors at login because of these missing applets sudo apt install mate-desktop-environment mate-applets For KDE-Plasma sudo apt install kde-full For Gnome.

  19. Oh, I'm sorry. Is there any reason why you would want another A20 board? It's an old SoC. Support for it is going to dwindle. If you'd like to stay with Allwinner then an H3/H5/H6 board would have a lot longer lifetime/support. I believe you want SATA. I don't know that many boards with sata on-board. The Orange Pi +2 has an H3 and SATA and is supported. You could also go for an SBC with USB3 and connect your drivers over USB3-SATA. Then an H6 might be good. I like the Pine H64 model B the most. But it's still in development fase. The RK3399's are more expensive, but bring a lot more connectivity. The NanoPi M4 for example has PCIe over GPIO's what can fit a 4 x SATA hat. It's hot 2 USB3 controllers for each 2 ports. All I can find that's supported in Armbian with the A20 + SATA is the Olimex Lime 2 and the Cubietruck. I do not know those boards or board makers. Maybe someone else knows more about A20 boards.
  20. Hi. You can keep using Armbian on it even when it's EOL. It just isn't updated anymore, and it loses support for it. I do not think you'll find a better supported OS for it. Either you will have to do with an unsupported OS. Or you could upgrade to a newer board. Greetings.
  21. That indeed isn't good at all. I'm from Europe so I haven't got a clue where to buy when you're from South-America. It's this PSU. I'm using a different one for it, a 4A EU PSU. But 3A should be sufficient. This is what you need to look for : 5V (at least) 3A Type H 3.5mm OD/1.35mm ID barrel ‘coaxial’ type I'd trow away that PSU you've got before it damages anything(hd/sd-card). I've seen a lot of undervolting in my times but under 4V is very rare. With a good PSU/cable you should never go under 4.8V. (tell that to the raspberry pi foundation) Good luck, greetings.
  22. Hi. Did you try with other devices on your network? Just to be shure it's the N2 and not a router issue. There were simular problems in the beginning with the N2. Those were indeed fixed with the latest uboot. This was also not with all N2's the same. Mine had it, some other didn't have this problem. Ethernet worked when put at 100Mbit, but wat Gb it lost all it's packages and was as slow as B/s. This problem is still not fixed in the Mate image to my knowledge(only after upgrade) Meveric did update his Stretch last week to fix this. Have you tried that image? Here was a fix for that problem. I do not expect you've got the same problem. I do think it could be related. Quote of myself : There's an easy fix for that. Quote from fromport: So powered down my N2, put the SD card in a USB reader connected to my linux desktop. Downloaded new uboot from I used the odroidn2-22 image. Downloaded and extracted the tgz file (not source) used the supplied script to install it to my uSD card: Code: Select all cd sd_fuse ./ /dev/sdb #<- that is where my system detected the uSD card 1664+1 records in 1664+1 records out 852336 bytes (852 kB, 832 KiB) copied, 0.113748 s, 7.5 MB/s Finished. End Quote. I've got the same issue with both Ubuntu and Stretch. But with Ubuntu wifi works out of the box, while in Stetch you need to be able to download a few things to get it to work. And that doesn't work without internet...
  23. Hi. It isn't an Armbian problem, but a problem with the Odroid kernel. More info here. It's the same with Ubuntu Mate from Odroid. With kernel 5.1 from Balbes zram-config works fine. I manually configure it after installing zram-config and all works fine. Meveric uses his own script for zram zram-odroid or odroid-zram. That does work on his Stretch. So that could be a clue. Zram and swap used to not work completely. I'm happy we've found the cause of that. I think this proplem is some crums left that weren't cleaned up.
  24. Good you've found a solution. All tho I can't advice anyone doing this. You could also try to cool the board better. Bigger heatsink, a fan. The H3 isn't that hard to tame. Do you play those games with Armbian? May I ask what you use? RetroArch I guess? Have fun
  25. To be future proof USB 3.0 is better. But all mine are USB2. Transfer rates are a lot higher with USB3, so I expect it to consume a bit more. Dit you try it on the USB2 ports of the Rock64? Did you try other storage devices on the Rock64? Do they mount ok? I should have a 2.5" drive laying around and I've got a usb3 to sata adapter. If I find time I'll try it out. Can't promise anything.
