  1. Hi, while toying around build system for Odroid C1 I saw that toolchains for arm-linux-gnueabihf where "old" as we are at "gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf" since the 7.3.1 looks like it is not available for this platform. So I did some changes in lib/ and added the following as a fast hack: "" "
  2. Hi there, I was playing around with the new sun6i-csi driver and was able to capture up to 800x600, but if I try to capture with a higher resolution it will always fail: fswebcam -S 5 -d /dev/video0 -r 1600x1200 -p YUV420P test.jpg --- Opening /dev/video0... Trying source module v4l2... /dev/video0 opened. No input was specified, using the first.

  3. Hello, I have had a look to the new Development Image (Armbian_5.76.190228_Tinkerboard_Debian_stretch_dev_5.0.0-rc8_desktop.7z) My SixFfab Hat which was working like a charm on 4.19-20 kernel. Any changes to add supoort for this Hardware again? Do you need any additional information? Many Thanks Roman
  4. Warning: This whole thread is only about historical information now since it's 2018 and we can buy inexpensive and great performing A1 rated SD cards in the meantime. Buying anything else is a mistake so directly jump to the end of the thread for performance numbers and recommendations. Edit: See an early 2017 update at the end of the thread regarding new SD specs also covering random IO performance. Edit 2: Some thoughts/observations on lifespan/reliability of SBC storage: (see also/especially the comments
  5. As already done with other topics this will be the start of a new thread collecting more information over time. Since we had a lot of annoying discussions recently regarding Wi-Fi on Orange Pi Zero and in general I thought let's give it a try a few days ago. I did some preparations in the meantime (monitoring 24/7 Wi-Fi throughput in 2.4 GHz band for example) and then started to test in a not too crowded environment here. As a start some quick Wi-Fi tests with a random 'quality' USB Wi-Fi dongle and 3 different Wi-Fi chipsets that can be found an a few boards Armbian su
  6. This is some more research based on prior efforts. The goal is to make more efficient use of available RAM. If the system runs low on memory only two options are possible: either the kernel invokes the oom-killer to quit tasks to free memory (oom --> out of memory) or starting to swap. Swap is a problem if it happens on slow media. 'Slow' media usually describes the situation on SBC. 'Average' SD cards (not A1 rated) are slow as hell when it's about random IO performance. So swapping is usually something that should be avoided. But... technology improves over time.
  7. With this commit I added 7-zip benchmark reporting to Armbian now. Will be available after next updates and with next batch of new images. Why not recommending to just do an 'apt install p7zip ; 7zr b'? Since 'fire and forget' benchmarking is always BS. You need some monitoring in parallel to know whether your system was really idle and at which clockspeeds the CPU cores were operating (throttling occuring or not?). Most recent 7-zip contains an own routine to 'pre-heat' the system prior to starting the benchmark (to let cpufreq scaling switch from low clockspeeds to h

  9. TL;DR: All available H3 boards do not differ that much. But the few differences sometimes really matter! The following is an attempt to compare the different available H3 SBC that are supported by Armbian. The majority of boards is made by Xunlong but in the meantime two more vendors started cloning the Xunlong boards (and also Olimex is preparing H3 boards as OSHW). Both Foxconn/SinoVoip with their Banana Pi M2+ and FriendlyARM with their NanoPi M1 tried really hard to copy everything as exact as possible (the so called pin mappings -- how the many contacts the used H3 SoC is prov
  10. Starting to work on lets call it the "dogafu" experiment (don't give a fuck about recommendations). This would combine my threads about powering & bad SD-Cards. Cause I want do something useful and not just crash armbian on a system, from which I know that it would happen, I decided to do not only stupid tasks on my OPi zero. I could just hammering the SD-Card with a webcam and motion until it crashes and write on this thread 'opi 0 with terrible setup crashes after x days'. But, nobody would read this thread cause it's not interesting for anyone. We know that this would happen and for t
  11. The following is the start of a series of tests regarding minimized consumption mode for SBCs. Idea behind is to provide Armbian settings that allow some of the SBC we support to be used as cheap and low-power IoT nodes (or call it 'home automation' or anything else, at least it's about low-power and headless useage) I start with some consumption comparisons with various RPi models below just to get a baseline of numbers and to verify that my consumption monitoring setup is ok. Also you find a lot of numbers on the net that are questionable (measured with inappropriate equipment, co
  12. First i have to say - if i knew what i am gonna go through, i would never buy this troubled hardware. So don't buy it too. But if you are already strayed like me, i decided to share my modifications, to make this inconsiderate piece of hardware useful. With this mods the device finally work as i need it to and i am fully happy with hardware part. Not so happy with software though, but that's another story. The main reason for me, to buy this router, except pc like capabilities, was SATA+SATA power connector. I used my old router with usb HDD, so it sounded good to have it in box and on na
