  1. It says, that adding an usb ar9271 wifi card to a pinephone is not feasible because the wifi card uses to much power. How much power is acceptable for an usb ar9271 wifi card to use? I do not have extended equipment. I made the following arrangement. One pc. Connected an usb power meter. Connected an usb ar9271 wifi card to the usb power meter. Started
  2. Hi all. I've made a new video where I test all storage devices for the NanoPi M4. 8GB, 16GB and 32GB eMMC modules, NVMe drive, sd-card and SSD over USB3. Here's the video. Here's my gathered data. Storage speeds -------------- 8GB eMMC module read : 160 MB/s write : 11 MB/s 16GB eMMC module read : 175 MB/s write : 50 MB/s 32GB eMMC module read : 173 MB/s write : 111.6 MB/s 256GB NVMe read : 697.7 MB/s write : 401 MB/s (630MB/s for 2.5GB, then 300 MB/s
  3. the main proposal of this research is to enable cached apt archives for docker build. first apt cache can be saved by a docker volume, but due to `${SDCARD}/var/cache/apt/archives` is not a constant, then we can't use `-v=apt-cache:${SDCARD}/var/cache/apt/archives` to enable it. so I use `-v=apt-cache:/root/.apt` as a tmp place for apt cache, when need `apt install` in `${SDCARD}`, use `mount -o bind /root/.apt ${SDCARD}/var/cache/apt/archives` and after install finishes, `umount ${SDCARD}/var/cache/apt/archives` this looks perfect, but after I check /root/.
  4. Hi there, I'm currently struggling to get the Cedrus VPU up and running. I have downloaded the specific version from bootlin and got the kernel up and running, however the V3s isn't supported by the Sunxi SRAM driver. This driver is important to get the VPU going. I tried altering the devicetree of the V3s to match a SoC that is somehow similiar, but it clearly failed for obvious reasons. I get this error message: [ 1.035259] cedrus Failed to claim SRAM [ 1.040990] cedrus Failed to probe hardware [ 2.478
  5. As WiringPi was never meant to support other boards nor does the author like to support other boards and it is officially depreciated now ( I want to ask why not put some efforts into libmraa and put it into the Armbian repository. I have already a fork which fixes Rock Pi 4 on recent mainline 5.3 kernels with updated debian build scripts here:, so debian packages could be simple built using dpgk-buildpackage. Why I think it is a good idea to supply
  6. Just curious, it has exists as patches for years, is there anything prevent it from being merged into mainline? This chip is quite widely used in TV boxes.
  7. Free software is software you may use, share, modify and redistribute. Replicant has decided to investigate if they can port a replicant version to the phone. Replicant has said, they know of no phone better about free software. All modems on the market require non free software. Same about the modem in the pinephone. A downside of the pinephone is the wifi card, 8723cs, because it requires non free firmware software. On pinephone's irc I was told, they went for the 8723cs because pinephone could find no viabl
  8. When building a kernel the device driver configuration asks which rtc should a system use for NTP and startup synchronisation . By default this is rtc0. The question is: In case there are more hardware RTCs in one embedded system ( in my case onboard RK808 and Dallas DS1307 over I2C), which one would be numbered as rtc0? Threre are several RTC device drivers available and checked by default, some marked as M and other as '*' , supposing 'module' or 'driver' respectively. Now if I have two hardware RTCs, I presume they should load as rtc0 and rtc1, but which part does numberin
  9. What script is used in Armbian to build ram init image uInitrd?
  10. mainline kernel support, libreelec is allready working. is there any chance on getting amrbian ported here, i allready did some test and made it boot, but network does not get an ip adress link with ethtool show up and 1 gbit. same for the eachlink device
  11. I'm creating this topic to track progress with support for EachLink H6 support. So far with patches in lines 127..202 in List of patches with patch files I was able to get: working: -boot with mainline 5.4 kernel -HDMI video (with correct DDC) -HDMI audio -Ethernet -GPU mali t720 -USB2/USB3 ports -CPU temp reading -DVFS (CPU freq scalling) -internal IR sensor (MCE remote works nicely) not tested: WiFi Blutooth This box might be cheap H6 box to become nice mediaplayer as current panfrost started to s
  12. Today I noticed something strange about packages : armbian-config and armbian-firmware (bionic all) Repository version becomes 19.11.3 (via apt update) but self built packages created via kernel build script are version 5.98 Other kernel packages are ok, version 4.19.85 What about this?
  13. I dont know if it real (but for me it feels like) that updating packaged (fetching/reading the list) takes much longer than on stretch or a bionic version. (also on buster creating locales via armbian-config - I use de,gb and us - does take longer to generate) While do a apt update I did see that buster do get package/content lists will come for armhf and aarm64 - is that OK or to much? Get:8 buster/main arm64 Packages [7728 kB] Get:9 buster/main armhf Packages [69.6 kB] Get:10 https://ap
  14. I do not wish to make this too political. But I do often get the question if we can trust all the images from board makers security wise. I personally try many images. I only use Hardkernel images on my Odroids. On my NVIDIA Jetson Nano I of course use the image from NVIDIA since it's got all the goodies. But on all other boards I use Armbian. Either official Armbian, or Balbes Armbian. I wanted to hear your thought about this.
  15. Hi every body I work with armbian on OPI & BPI fine but I'm looking for an improvment. First I install OS on SD, etc... but with limitations of R/W nb & sensibility if power disappears. I set a boot os SD and after switch on SSD connected on USB by moving directory and after discover a scipt whic do all automatically (thank's armbian). But customer calls me server don't restarts. I go on site (waste of time) burn a new SD etc.... and install a little eaton ups to prevent new failure. The server hosts a little bootstrap webserver, specific application server, cron scripts and nothi
  16. BPi M1 A20 with kernel 5.3.7/5.3.8 there are some problems using the onboard-analog-audio mpg123/espeak is freezing and cant write to the analog-audio via alsa. A USB-Audio-dongle does work fine. (also EOS devices like PCDuino A10 and Lime A10 have audio sync-problems with kernel 5.3 (but do work) - but its "OK" they are EOS) The BPi M1 A20 has no problem with the analog-codec while using kernel 4.19.81-sunxi analog-codec seems to be always active, because if enabled as overlay or not the analog-soundcard s shown: aplay -l **** List of PLAYBA
  17. One month ago I got on my OPi Zero Plus2 H5 only up to 816Mhz with armbian. In the past I got on this device up to 1.1GHz (1080000 cpufreq) with older armbian builds. @5kft Told me thats because frequencys greater than 816Mhz require 1.2v and the OPi Zero Plus2 H5 isnt/couldnt switch(ing) and would only run at 1.1v. So it seems the cpu-table is now more conservative than before. Yesterday I did see the same behaviour and my "older" non-LTS NanoPi Neo2 (H5 also). Because in September I edited the cpu-table less conservative for the OPi Zero Plus2 H5 I
  18. Hi, I'm looking for a tiny board with eth and wireless. My first choice is Orange Pi Zero but I'm worried about thermal issue. Any cheap alternative?
  19. Hi there, I have a RockPi 4b running Arabian with Ubuntu bionic. I mainly use the board to contact it online over ssh/vnc/rdp to work in spyder and texmaker. Quite often the connection is slow however. Therefore I am thinking of changing the system such that i can just bring it on the road and connect it using a local network with the usbc cable outlet of the iPad and a USB port on the rockpi. The reason i would like to connect over a cable is speed and not having to use the WiFi so that both devices can still easily connect to a WiFi network for internet access. I have found many
  20. Which one is better from below two options >> (1) Western Digital WD Blue 250 GB M.2 2280 SATA Internal Solid State Drive (WDS250G2B0B) OR (2) Samsung 860 EVO Series 250GB M.2 SATA Internal Solid State Drive (MZ-N6E250BW) Please suggest as per your experiences...
  21. This was a bit of a buzz back in late Dec 2018, and things got kind of quiet after that... Rumour was that the SoC was the SocioNext SC2A11, which is a Japanese chipset (and from experience, Japanese chip vendors are very particular about who they work with)...
  22. I got a little problem I interrupted the first lines of the and now I do get the error: root@core2duo( ./ EXPERT=yes bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell I did found out that when entering the command "exit" this shell will close and the normal menu driven compile gui does start, but maybe anyone could give me a hint to resolve this issue? Many Thanks in advance
  23. Hi all, Is there some documentation or How To on how to debug the boot process ? I posted before I am trying to bring up a AW-SOM-A20 board that gets stuck at boot. I am kind of at a loss so I figure next step is to use the kernel debugger, which I have never done on linux (I have experience with darwin/mac OS and freebsd though) Is there a build option for armbian so that the debuggable kernel image is left around in the build process ? All help appreciated, thanks Bruno
  24. I have some patch files, and one of them leads to a .dts file not being compiled. I'd like to find what is wrong with the dtc compilation but I do not know what the exact command the armbian build script runs, so I can't reproduce... Is there a way to make the build totally verbose and see the command being executed ?
  25. I've been working on a project to boot a custom kernel on my NanoPC-T4. I haven't gotten too far though because as soon as I make the smallest change to the source, everything goes to hell (see below). I've built 3 images following EXACTLY the same process. All I did was change the KERNELBRANCH variable in userpatches/lib.config to point to different branches in the same repository. For completeness, here's my lib.config (which simply points to my fork of ayufan-rock64/linux-mainline-kernel): KERNELSOURCE='' KERNELBRANCH='branch:BRAN
