Hi all, I was struggling to have a stable Wifi connection on my new Orange Pi Primes, and believe I found a solution, so I thought it's nice to share it Symptoms: Wifi would connect right after reboot, but would disappear if Orange Pi Prime was idle for about 30min. The only way to reactivate would be to either pull the cable out (as there are no buttons yet), or to login via ethernet, perform ifconfig down && if config up. I didn't liked either of the options, so I decided to investigate. My log was full of: [89201.577208] RTL8723BS: nolinked power save enter [89201.967063] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [89202.187266] RTL8723BS: nolinked power save leave [89208.120724] RTL8723BS: nolinked power save enter [89214.307901] RTL8723BS: nolinked power save leave It's clear that power saving was a culprit, so I needed to find how to disable it. Attempts to solve the issue I tried disabling power saving using iwconfig command, but that didn't work: $ sudo iwconfig wlan0 power off Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; Operation not permitted. I also tried doing that from Network Manager, by editing /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf: $ cat /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf [connection] # 2 = power saving off # 3 = power saving on wifi.powersave = 2 $ mv /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf /etc/NetworkManager/conf.d/default-wifi-powersave-off.conf but that didn't work either (even after reboot). Working solution Seems that RTL8723B (Wifi driver user by Orange Pi Prime) can only set powermode during module load, so I created /etc/modprobe.d/r8723bs.conf with following content: $ cat /etc/modprobe.d/r8723bs.conf options r8723bs rtw_power_mgnt=0 rtw_enusbss=0 $ ls -lsa /etc/modprobe.d/r8723bs.conf 4 -rw-r--r-- 1 root root 47 Jan 11 10:07 /etc/modprobe.d/r8723bs.conf (make sure ownership and permissions are right), and after a reboot, Wifi remained up and running for days. Hope this helps someone.

My Orange Pi Prime freezes when compiling anything major (Ruby, CPython). It completely locks up halfway through. No error or kernel panic from serial either. HDMI output goes black. I've tried: Better cooling, different brand SD cards (Sandisk Ultra, Samsung Evo from reputable suppliers), different power supplies, and even disabling swap. Tried my Lab Bench Power Supply at 5.00, 5.10, 5.20 and 5.35 volt, volt drop is about 0.1 volt measured at the board, and power usage at 400-700mA depending on the load. Tried `stress` in all sorts of configurations for times up to 1 hour, this does not crash the board. Iozone also does not crash the board. Does anybody know about any reason why this might be happening or how to solve it?

I'm looking to compile a kernel for Gentoo (Orange Pi Prime), but afaik the HDMI support has not been mainlined yet. Does anybody know how Armbian kernels have it? And is there more to it than just the kernel sources? Last time I tried, I had no luck getting output.

with hdmi figured out. Rather, he himself earned a normal. It could be seen that a reboot was needed. Therefore, I rename the topic Has anyone tried to use the Majordomo for Armbian? Have experience? I want to try using orange pi for a smart house

Hi! Could you please clarify, is there a way to increase default limitations for max cpu freq (H5) on Orange Pi Prime? As i understand, according to driver (cpufreq-dt): /etc/default/cpufrequtils is a bit less restrictive: Is this a driver limitation ? Or there is a way to increase cpu-freq, but it's not used by default ? ( ... and why, if it is so ?)

After upgrade ubuntu server stops booting and working on Orange Pi Prime (H5, 2GB, WiFi...). Upgrade goes from image (Armbian_5.32.170706_Orangepiprime_Ubuntu_xenial_dev_4.11.8.img) correctly (sudo su... apt-get update, apt-get upgrade, plus install of mc, apache2, mysql, php, phpMySql ... apt-get autoclean). After it is done, I log in using Putty, and the system is still usable but on the login screen there is a message "Kernel upgraded, please restart" (or similar). once logged in I did "init 6" to restart, and Putty is disconnected, and no more response. that is it. Pressing any buttons on the board, disconnecting and reconnecting network, disconnection and reconnecting power supply produces no results. Only network and power are connected to the board, no keyboard or screen since it is meant to be a small web server. Not even LEDs turn on. It appears completely dead. After I replace the image on the SD card, the Pi starts working again normally. I am using 4GB SD, and initially there is some 50% free space. After upgrade I think it drops down to 40%, but there is still sufficient space. CPU is warm to touch, I would assume some 40-45' C (105-115' F). The rest of the board is cool. I repeated the process 3 times up to now, assuming that it was my error, but with same results all 3 times. I still didn't try checking the card on another Linux PC, since I have access only to "Ubuntu - Live CD". Please help.

Hello guys, i have a orange pi prime. I'm download to https://dl.armbian.com/orangepiprime/Ubuntu_xenial_dev_desktop_nightly.7z this image and i flash to 32 gb sandisk card. System is not opened, i see "starting kernel" message and some controls after it's rebooting continuos. I dont start it. I'm waiting for your helps. King regards

Hello! Explain to me please, what's the problem with support for H5 processors? Drivers located here: https://developer.arm.com/products/software/mali-drivers/user-space , and here: https://developer.arm.com/products/software/mali-drivers/utgard-kernel , not enough?

Hello, I know that armbian for orangepi prime is under development. Armbian does not detect the integrated wifi, and I'd like to know if it's not implemented yet or it's happening just to me

Just got mine Prime and installed on microsd Armbian-server for that. After setting up root password and new user, have edited /etc/network/interfaces to have uncommented these lines source /etc/network/interfaces.d/* auto eth0 iface eth0 inet static address 192.168.0.106 netmask 255.255.255.0 gateway 192.168.0.1 dns-nameservers 8.8.8.8 8.8.4.4 auto lo iface lo inet loopback every manual says it should be easy like that... but it doesn't work where to dig next?

Hi! Thanks for your amazing work, i'd like to have knowledge to give a hand After a few problems I've been able to boot my new Orange Pi Prime, but no keyboard is working on it. I've tried with an USB keyboard and a bluetooh one, but there is no way to make them work. No clues on dmesg, lsusn looks fine... Any idea about hoe to debug it?

Are there plans for an armbian version for the new Orange Pi Prime? Hardware specs look very similar to the PC2 but it has 2GB RAM which makes it an interesting SoC.
