  1. I had a ralink wifi dongle in a drawer. I've connected it and it is working like a charm. Thank you anyway for your great support in armbian development
  2. Hi Yesterday I've upgraded armbian kernel from 20.11.3 to 20.11.6 version in the available updates with apt update. Once PiPC restarted no wifi connection was found. The wifi dongle is a TP-LINK TL-WN725N and is found with lsusb: Bus 004 Device 002: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter It was working with previous kernels but with 20.11.6 kernel is not listed in ifconfig so I've rolled back to 20.11.3 kernel Any hints or solucions ?? Thanks
  3. Thanks guidol As I said before if /etc/default/cpufrequtils is renamed that CPU option in armbian-config is unavailable I don't know exactly why that file was renamed in my case.
  4. Surely I saw mistaken info I have /etc/default/cpufrequtils.dpkg-old instead of /etc/default/cpufrequtils so no CPU frequency from this file is loaded at boot. Defaults for max frequency is: root@orangepipc:~# cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_max_freq 1368000 So I guess if it's not loaded /etc/default/cpufrequtils because it has been rename (after kernel upgrade maybe??) to /etc/default/cpufrequtils.dpkg-old is taking the default max frequency ... am I right ?
  5. Thanks to you all for answering I've a power consumption meter and I'll be monitoring the different parameters today. At the moment after 20 minutes the max intensity (including boot) is 40 mA (25 mA currently), 4 W max potency (during boot I supposed) 2.5 - 3 W currently. Theoretically the PSU must give 5V x 2.5A around 12.5 W (nominal power output). I think is far away from the limits, but nothing is discarded. OpiPC nominal CPU frequency is 1.6 GHz (1600 MHz), I think is not reaching that top value and anyway I have not overclocked it, just with the st
  6. An old tablet charger, 5,15 V (real) 2,5 A output connected to a UPS through DC jack plug. Do you think it may be the problem ? Seems to be working fine since 2 years ago.
  7. Thanks for answering Igor but I don't know exactly what you mean.... what power scheme setup? Sorry if I don't understand but I have only basic knowledge Anyway why after rebooting wifi and bus are disabled and syslog stops logging ?
  8. My Orange Pi PC is restarting without apparent reason at random times and wifi and buses are disabled. The last lines of log always say the same: [ 25.644949] IPv6: ADDRCONF(NETDEV_CHANGE): wlxf4f26d1c6002: link becomes ready [ 33.781109] vcc3v0: disabling [ 33.781136] vcc5v0: disabling [ 33.781146] usb0-vbus: disabling armbianmonitor link: Thanks in advanced
  9. Perhaps was outdated.... anyway I've edited /etc/armbian-release with former opipc values and armbian-config has loaded the sunxi kernels and I've installed the latest version. Everything is like before and ok.
  10. Hi Yesterday after installing weewx I uninstall python 2 but well.... something went wrog because there was no welcome screen login with ssh. I've managed to install armbian-config and everything is right again except the release has changed from Orange Pi PC to xt-q8l-v10 Any hints to roll back to the former release ?? I've attached armbianmonitor url Thanks in advance
  11. First of all I've got an OPI PC and I'm newbie with armbian and Linux in general I've managed to read DS18B20 temperature sensor and now I want to read Temp and Humidity from a SHT75 sensor which has the same specifications as the SHT1X family of Sensirion sensors. I've installed WiringPi library and I've been searching on google how to make SHT75 work with little success Any documentation or examples to see?? Any help would be appreciated Thanks
