I tried also external and internal pullup, Kernel is Armbian 20.08.17 Bionic with Linux 5.8.16-sunxi L.

I tried other pins and other DS18B20 and there was the same issue. Same issue with an Orange Pi one. Then I tested two Rasperries -> everything is ok. I will switch to a Raspberry. L.

Now I removed the DS18B20 from the Orange Pi zero and Uuups: pi@orangepizero:~$ ls -l /sys/bus/w1/devices/ total 0 lrwxrwxrwx 1 root root 0 Nov 17 17:33 00-100000000000 -> ../../../devices/w1_bus_master1/00-100000000000 lrwxrwxrwx 1 root root 0 Nov 17 17:34 00-500000000000 -> ../../../devices/w1_bus_master1/00-500000000000 lrwxrwxrwx 1 root root 0 Nov 17 17:33 00-900000000000 -> ../../../devices/w1_bus_master1/00-900000000000 lrwxrwxrwx 1 root root 0 Nov 17 17:25 w1_bus_master1 -> ../../../devices/w1_bus_master1 pi@orangepizero:~$ dmesg | grep w1 [ 10.748887] w1-gpio onewire@0: there is not valid maps for state default [ 13.130265] w1_master_driver w1_bus_master1: w1_search: max_slave_count 64 reached, will continue next search.

I found an error in the U-boot messages: ** File not found /boot/boot.env ** Therefore I took a new SD-card and copied Armbian 5.65 with kernel 4.14.78 onto it. Same error occurs. Could this be the reason for the wrong display mode?

I have the same problem with an orangepi one and ARMBIAN 5.60 stable Debian GNU/Linux 9 (stretch) 4.14.70-sunxi I have a VGA Monitor connected via a HDMI-to-VGA adpater which runs well under Armbian 3.4 and h3disp set to 1024x768@60 which is the max resolution of this monitor. The adapter also runs fine with my normal monitor Hanns.G and with any PC I own and any resolution. When I changed to Armbian 4.14, the resolution of the video output is always set to 1920x1080@60, regardless which parameter I change in /boot/armbianEnv.txt or /boot/boot.cmd recompile and boot twice. I also tried 800x600 and 640x480, nothing works. Tnx L

Try the /etc/udev/rules.d/97-gpio.rules from https://linux-sunxi.org/GPIO

The Orange Pi Zero Plus has only a CVBS/FBAS/RCA video output, therefore I believe that only a televison but no VGA or DVI/HDMI monitor can be used (or headless use). Has anybody an idea how to convert CVBS to VGA or DVI/HDMI? L.

It also runs on Armbian 4.14.18 and 4.14.65 with no root privileges, but you must change the file # /etc/udev/rules.d/97-gpio.rules SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c '\ chown -R root:gpio /sys/class/gpio && chmod -R 0770 /sys/class/gpio &&\ chown -R root:gpio /sys/devices/platform/soc && chmod -R 0770 /sys/devices/platform/soc'" add a group gpio and make the user member of this group, then reboot

I downloaded Armbian_5.38_Debian_stretch_next_4.14.14 for the orangepi-one and startet armbian-config. In dpkg-reconfigure keyboard-configuration I changed the layout to german-german but it has no effect, the layout remains to the international layout (qwerty etc).

Hi, can anybody tell me, why the rights on the serial port ttyS0 are R/W for the user (root), but only W for the group (tty) ??? crw--w---- 1 root tty 251, 0 Jan 24 19:45 /dev/ttyS0 Hardware is orangepi one, OS is Linux pi-one 3.4.113-sun8i #6 SMP PREEMPT Tue Jan 16 14:36:25 CET 2018 armv7l GNU/Linux I can change the rights with chmod, but the change is not permanent after a reboot. L.

A question abaout iozone: is it possible to use another SDCard eg in an USB-reader in the USB-port ?

under armbian 5.35 Debian Jessie 3.4.113-sun8i I added the following file /lib/systemd/system/getty@tty1.service.d/20-autologin.conf with root privileges: # /lib/systemd/system/getty@tty1.service.d/20-autologin.conf [Service] ExecStart= ExecStart=-/sbin/agetty --autologin pi --noclear %I $TERM If needed, change 'pi' with another username. Then reboot.

It would be fine and eysier for newbies if the udev-rule would be integrated in Armbian or in armbian-config.

I found a method to access gpio without root privileges, look here

Thats's easy to find out. Look at the directory /sys/class/gpio, there is a link to /sys/devices/platform/whatsoever/gpio/gpiochip0, change whatsoever with the real findings and drop gpiochip0. That's the way I did it. Maybe it depends on the hardware (I use an opi one) or the Linux (I use Armbian 5.35 Debian Jessie 3.4.113).

on Orangepi One you have to add a file like /etc/udev/rules.d/99-gpio.rules SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c '\ chown -R root:gpio /sys/class/gpio && chmod -R 770 /sys/class/gpio;\ chown -R root:gpio /sys/devices/platform/sunxi-pinctrl/gpio && chmod -R 770 /sys/devices/platform/sunxi-pinctrl/gpio;\ '" add a group gpio and add the user to it, then you have rootless access to gpio

It would be GREAT if rootless access to gpio was integrated in armbian (just like in raspbian). I made a little test on my Orangepi-One: created a group gpio and added the user to the group gpio, then created the file /etc/udev/rules/99-gpio.rules, this makes the access rootless # /etc/udev/rules/99-gpio.rules SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c '\ chown -R root:gpio /sys/class/gpio && chmod -R 770 /sys/class/gpio;\ chown -R root:gpio /sys/devices/platform/sunxi-pinctrl/gpio && chmod -R 770 /sys/devices/platform/sunxi-pinctrl/gpio;\ '" Edit (02/09/2018): for later versions of armbian the file must change (tested with 4.14.18 and 4.14.65): # /etc/udev/rules.d/97-gpio.rules SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c '\ chown -R root:gpio /sys/class/gpio && chmod -R 0770 /sys/class/gpio &&\ chown -R root:gpio /sys/devices/platform/soc && chmod -R 0770 /sys/devices/platform/soc'" Now you can use the access on the bash for the PIN PA12 (calculation see https://linux-sunxi.org/GPIO) echo 12 > /sys/class/gpio/export # enable access to PA12 sleep 0.1 # wait some time to become gpio12 active echo out > /sys/class/gpio/gpio12/direction # PA12 is output echo 0 > /sys/class/gpio/gpio12/value # PA12 is low echo 1 > /sys/class/gpio/gpio12/value # PA12 is high echo 12 > /sys/class/gpio/unexport # disable access to PA12 My skills in programming are not good enough to transform this to C, C+, Python etc, but you don't need any root privileges.

The problem seems to access /dev/mem, crw-r----- 1 root kmem 1, 1 Nov 28 22:17 /dev/mem If you change the group or add normal user to group kmem nothing changes -> you must be root to access. Also if you chmod /dev/mem to 0777 -> you must be root. Perhaps the makers of armbian can change something here.
