@royk thanks for the answer but this Virtual Desktop is out of the discussion, what I want is to reach the same point that I had experimented with Raspberrypi. With the raspi-config I could set a fixed resolution that was activated even if there was no display connected to the hdmi. Achieving this result would be the goal of this discussion, thanks anyway!

On my Orange Pi 5, I have successfully installed the X11VNC server. I followed the guide at the following link X11VNC and everything works as expected. I can connect with Real VNC from another device and see the desktop of the Orange Pi as if I were in front of its display. However, when the Orange Pi 5 is powered on without a display connected to the HDMI port, the access with Real VNC doesn't work as before. I get a black screen and I am unable to interact with the Orange Pi. I had a similar issue with Raspberry Pi, where I could resolve it by setting a default screen resolution. How can I achieve this with Armbian? How can I configure an alternative resolution when the HDMI port is not connected?

I managed to solve the problem by myself! I found that I had a number of libwiringPi files inside the /usr folder, they are probably left over from previous attempts to install the wiringpi library. I removed these files manually and then proceeded to install the correct library After this gpio readall started working again

I don't know why, I think after doing "sudo apt update/upgrade" (but I'm not sure), the wiringOP library on "orange pi 5" with Armbian 23.02.2 doesn't work anymore. If I run the command "sudo gpio readall" I get the following output: Oops: Unable to determine board revision from /proc/device-tree/system/linux,revision or from /proc/cpuinfo -> No "Hardware" line -> You'd best google the error to find out why. Can anyone help me solve this problem?

@royk Unfortunately it doesn't work for me, but I have to do a test by grounding the input, I'm doing it this weekend, thanks

@royk With the command you suggested, when I run the code it no longer gives an error, but sadly the interrupt doesn't work! Is it possible that the orange PI 5 interrupt is not implemented at the hardware level?

Hi @royk i check with the next branch is the same problem...

Hi @royk thanks for the answer, I had already looked in the library but I can't find anything different from the code I use, if you look at the isr.c example the call is the same as the one I use, except for the number of PINs that goes from 0 to 7, I tried to put PIN 0 but nothing changes, always the same error.

Hello Armbian forum, I need to have a GPIO interrupt on Orange PI5. I have successfully installed WiringOP and I am using it with C code. The problem is that the interrupt is not working, and I am receiving the following error. How can I proceed? Does anyone know how to enable the WiringOP interrupt on the GPIO PIN? Code C : #define AUX 13 wiringPiISR(AUX, INT_EDGE_FALLING, &MyFunction); Error: wiringPiISR: unable to open /sys/class/gpio/gpio92/value: No such file or directory PS. I have just successfully installed this version: Armbian 23.02 Jammy Gnome

Thanks @usual user for the reply, ok I also saw this way of describing the hardware in the post I linked at the beginning. Unfortunately I'm new in armbian (I apologize but I'm ignorant), so please I ask you to follow me in the next description. The following structure is located in the /boot folder: /boot -> dtb -> amlogic -> overlay -> dtb-6.1.11-meson64 -> amlogic -> overlay In the amlogic folders (both in one path and in the other) there are several .dtb files. Files named odroid-n2-plus are as follows: meson-g12b-odroid-n2-plus.dtb meson-g12b-odroid-n2-plus-spi.dtb Where is it determined which file is to be used? These files I can easily convert to dts and then compile dtb. Which files should I edit? In which path should I change them?

Hi @Igor thanks for the answer, the first thing I did is armbian-config: System -> Hardware -> uartA and uartB enabled, then reboot. Unfortunately it doesn't work! With "ls /dev/tty*" I see all ports tty0-50, ttyS0-7, ttyAML0, any port gives me input/output error when I access it. How can I edit device tree and enable this UART ? Where can I find the information?

Hello, i need to activate the serial port on the odroid N2-plus, the serial port is on pins (J2 - 2x20 PINS) 8/10. Usually this uart with ubuntu is at /dev/ttyS1. If I try to use it on armbian I get an input/output error. I read the following post, I understand that it is not implemented yet. Can anyone point me in the direction of trying to do this?

Hi thank you all now the audio works!

Hi all, after installing the latest version of Armbian (Jammy 6.1.11 desktop) I found that HDMI monitor audio is not working. With the Ubuntu MATE version of odroid the audio worked. Armbian seems more powerful and its look is much better than MATE, I hope I can solve all the problems because I don't want to go back to MATE anymore, How can I make HDMI audio work? Thanks in advance... PS. I have already updated the firmware to full with the WiFi USB stick problem which has since been resolved

Stop everyone, problem solved!!! I did a fresh install of the armbian image to start fresh. Then I ran "sudo apt-get update", then ran "sudo apt-get install armbian-firmware-full". At the end of this update I noticed that with "lsusb" the Realtek device had a strange "CD rom mode". Reading on the net I installed "sudo apt-get install usb-modeswitch" then executed at least twice the command "sudo usb_modeswitch -KW -v 0bda -p 1a2b". Then I found the wlan interface. With "sudo armbian-config" I configured the WiFi and now everything works fine! 💪 The only thing I don't like so much is that the WiFi interface is not called wlan0 but wlxa0d768106782 which is not very simple! Thanks Werner for the tip, I hope it can be useful to someone else 😀
