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.

Hello, the issue was closed by some change in my program that uses i2c connection (used write() instead of i2c_smbus_write_quick() function). The fix was applied after I discovered that i2cdetect call works correctly until my program is activated. Hope this can help to somebody with similar problem.

Hello, I am trying to port my developed module to the newest Armbian system. Once I had everything worked in very old Armbian developed in 2018 based on kernel 3.4. There is a hardware module connected via i2c1. When my program tries to communicate with it, it doesn't work and I get errors kernel: i2c i2c-1: mv64xxx: I2C bus locked, block: 1, time_left: 0 I've uploaded the diagnosis information to URL: https://paste.armbian.com/aciwalafah There was a problem also in Armbian 22.11 system. I upgraded it after found information about some solution for i2c probem with similar error messages. Please advise. Thanks.

Hello, fresh installed Armbian desktop OS detects attached HDMI display as full HD with correct resolution 1920x1080. But after some restarts it loads in u-boot with correct resolution and then, on kernel startup switches to 1024x768 and also desktop opens with this resolution without an option to increase it. The armbianEnv.txt file in /boot folder contains string disp_mode=1920x1080p60 and was not changed. Please advise.
