@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

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?
