Thank you for clarifying. I tested some image from Armbian, but it had several limitations for me. For example kernel v.6 had some problem with internal sound card in my test, while kernel v.5 works with it.

Thank you! I've checked it and it doesn't contain release for Orange Pi CM4. I went with image supplied in orangepi.org site and it answers my needs (in most cases). BTW, their image has something common with Armbian (or based on).

Hello, Could anybody provide plans/recommendations about Armbian and Orange Pi CM4 board? Thanks in advance.

Hi, I don't know, if this is relevant, but older version - 23.02.2 with Linux-5.15.93 works better about the resolution I need. Hope this helps.

Hello, I downloaded recent Armbian image for Orange Pi PC Plus - 23.05.1. When I run it, the screen resolution is 720x576 and virtual resolution 1024x768. I changed armbianEnv.txt - defined disp_mode=1280x800p60 (this is what I need) and also used fbset command in my application and it works in most cases, but sometimes after system restart the screen resolution is the default (720x576) and can't be changed - I get error - "ioctl FBIOPUT_VSCREENINFO: Invalid argument". How can this be fixed? Thanks in advance.
