RPI5 Console output Resolution (HAOS 13.2)

Installation Home Assistant OS

I recently replaced my PI3A+ with a PI5 and I am struggling to find the right settings for having the HAOS console output at 480x320 resolution on my HDMI Kedei 3.5inch display connected to RPI

With previous PI3A+ I simply had in \mnt\boot\config.txt the following lines:

  • framebuffer_width=480
  • framebuffer_height=320

On my RPI5 I also added the following lines:

  • hdmi_force_hotplug=1
  • hdmi_group=2
  • hdmi_mode=87
  • hdmi_cvt=480 320 60 6 0 0 0

But still the video output (console) is at FullHD resolution
It seems that on RPI5 (HAOS) these command doesn’t work/are ignored…

Is there some other commands to set the console output resolution at 480x320?

Thanks

Can anyone help?

Is it only me using a 3,5inch LCD screen connected to an RPI5?

Hi Stefano, check this: https://www.raspberrypi.com/documentation/computers/configuration.html#displays

Thanks Nick,
I know that page but since we are under HAOS all of those suggestion doesn’t work because of missing components …
I was wondering if some other HA RPI5 users already found the way to address properly the 3,5 Inch LCD screen…
Thanks

Of course I know that HAOS is not using Raspberry OS and at first I thought the solution would not be like with RPi OS but I was sure that it read that setting display options would be similar, no matter what OS.
Now I cannot find that anymore… :blush:
