  1. hi all . i got a old pandaboard only $20 by auction . i expirienced RS232C conection to install freebsd & arch (fail to install openbsd ) . RS232C is impressive to me . i guess that the armbian developers usually use rs232c . is it right ? if you have some interrest , please see http://akita-arm.blogspot.jp/2016/08/pandaboard-openbsd.html . two green palates is the thing on which we use kitchin knife on . it is easylly cut by scissors and holed out by electric drill and cheap only $1 . ------ thanks
  2. i find a page about heat sink of parallela ( http://www.rs-online.com/designspark/electronics/jpn/blog/content-1032). this also has lateral sid fan .
  3. hi all . when sysbench --test=cpu --cpu-max-prime=200000 run --num-threads=8 case 1) fan from upper , CPU temperature is 85 ~ 86 degree case 2) fan from lateral side , CPU temperature is 75 ~ 76 degree lateral is much better without fan Fri Jul 22 11:42:19 JST 2016 58 start lateral side fun Fri Jul 22 11:47:39 JST 2016 41

  5. i imagine banana pi 2 core -> 25 degree odroid-c2 4 core -> 55 degree nano pi M3 8 core ->85 degree then arm 16 core , 115 degree only imagination in fact odroid's 8 core ($79) has active cooling . --- regards ps: nano pi M3 has 3 problems 1) temperature : tkaiser solved 2) cannot use swap 3) cannot see youtube

  7. of course in japan , 10 yen coin ( about $0.1) is made by copper and is the cheapest material. the best is silver coin . are there coins made by copper in USA ? and acryl plate is easily holed out with metal drill . alminium cap presses coins against heat sink and so fixes coins and heat sink . i use
  8. i am suprising your vast knowlege . i only follow 'Install Cross Compiler' of http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M3#Boot_NanoPi_M3_from_SD_Card i use 64bit CPU and 64bit debiandog . i finally underastand that nano pi M3 is 64bit hardware but the present OS is 32 bit . surely nano pi M3 becomes hot and hot and suddenly reboot . so i made the device which misses heat . now there is no rebooting . Because it doesn't work easily, it's fascinating. Because there is mystery, a detective story is read. Because there is a mountain, it's climbed. so i think . --- regards http://akita-8core.blogspot.jp/2016/06/nano-pi-m3.html
  9. this morning , i try to boot nano pi M3 by rebuilded uIimage . nano pi M3 can boot , but swapon /SWAP swapon: /SWAP: swapon failed: Function not implemented --- regards
  10. about nano pi M3 cross compile is possible on debiandog64 (perhaps intel 64bit and debian etc 64bit) see -> http://akita-8core.blogspot.jp/2016/06/nano-pi-m3.html so diff .config .config-ori 53c53 < CONFIG_SWAP=y --- > # CONFIG_SWAP is not set 96d95 < # CONFIG_CGROUP_MEM_RES_CTLR_SWAP is not set 1801,1802c1800 < CONFIG_THERMAL=y < CONFIG_THERMAL_HWMON=y --- > # CONFIG_THERMAL is not set may show CPU temperature , but only posibility . --- regards
  11. i bought nano pi M3 . uname -ar Linux NanoPi3 3.4.39-s5p6818 #2 SMP PREEMPT Fri May 20 15:51:46 HKT 2016 armv7l GNU/Linux and cat /etc/apt/sources.list deb http://ftp.cn.debian.org/debianjessie main non-free contrib deb-src http://ftp.cn.debian.org/debianjessie main non-free contrib but CPU is very hot . but i can not mesure its temperature . (lm-sensors is not OK) usually armbian could make its temperature lower , this was done in case of orange pi PC . http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M3is a page of nano pi M3 ----- regards

  13. hi all . i think sd card is much shorter life time and restricted size ( 64G ~ 128G and big size is too expensive ). so as server , i like to use hard disk as root . for this purpose , nand-sata-install.sh is excellent ( but too complex for me to understand ) . i use nand-sata-install.sh on odroid-c2 armbian . and on working armbian , i run next script . ( the timing to attach sdb is about 10~15 second later after armbian booting ) . sda1 is cloned to sdb1 . clone-rsync-2-HDD-delete.bat ntpd -s date echo '--------------------' umount /mb1 mount /dev/sdb1 /mb1 df echo '--------------------' read X echo $X cd /mb1 mkdir -p bin etc home lib opt root sbin selinux srv usr var for x in /bin /etc /home /lib /opt /root /sbin /selinux /srv /usr /var do rsync -avHx --delete $x/ /mb1$x/ done cd /mb1 mkdir -p boot dev media mnt proc run sys tmp it works for me . --- detail is at http://odroid-akita.blogspot.jp/2016/04/odoroid-c2.html

  16. no cost heat sink idea . alminium bottle ( half cut fanta ) over copper heat sink over cpu . but radio wave interferes cpu or not ?
  17. i tried to install arch linux on odoroid-c2 . alike armbian , slim can not boot GUI .

  19. i see unixbench was outdated . i want to mesure cpu speed not hard disk speed . i do not know the tool . Once upon a time there was super pi and i used it . at present whic one is easy to do to measure cpu speed ? orange pi PC with armbian is very tuned up and is fast and i think it may be faster than raspberry pi 3 with rasbian . i think odroid-c2 must be fast considering its hardware .
