[PINN PI5 ] does not work with HDMI 1024 x 600

I have a Roadon 10 in touchscreen that works well with standard setups - both Rapberry PiOS and Ubuntu.

The initial PINN setup does not work with it, and there is no display. Connecting a multi-format display works.

I have modified config.txt to the Roadon screen definition but it is ignored on boot.

Definitions for this screen are:

Disable compensation for displays with overscan

disable_overscan=1

Specific to Roadom 7 or 10 in screen 1024x600

framebuffer_width=1024
framebuffer_height=600
hdmi_force_hotplug=1
hdmi_cvt=1024 600 60 3 0 0 0 0
hdmi_group=2
hdmi_mode=87

Try modifying cmdline.txt by adding the following text to the start of the first (and only) line:
video=HDMI-A-1:1024x600@60D
A-1 is for the first HDMI socket.

If you boot your Pi5 with this display and no drives attached, do you get a diagnostics screen?
Does it's output include EDID: OK?

Do you have an older model RPI (pi4 or earlier) that you can test it with PINN 3.8.7?

commented

Booting without any output gives me the Pi 5 diagnostic screen. MultiBoot (RonR) and all operating systems tried so far work. Pulling my dedicated Pi4 (Home Assistant) for test will take a bit.

commented

If you can use your Pi4, please try PINN v3.8.7 with it. With that your config.txt settings in your first post should work.
You can try the PINN 3.8.9 beta with your Pi4 as well, but your config.txt settings m\y not work. If not, add the video=HDMI-A-1:1024x600@60 to your single line of text in cmdline.txt.

Booting without any output gives me the Pi 5 diagnostic screen.

But did you see the EDID ok message on the diagnostics screen?

commented

It worked well using the Pi 4 and v3.8.7.

commented

It looks like it's ok. Hard to make out, it's very small.

commented

OK this may help.

Take your SD card with PINN 3.8.9 beta on it.
Download https://sourceforge.net/projects/pinn/files/beta/pinn-lite.zip/download and unzip it.
From the contents of the zip file, copy kernel8.img and pinn.rfs onto the PINN recovery partition of your SD card to overwrite what is already there.

Now you need to edit cmdline.txt to add video=HDMI-A-1:1024x600@60 to the one and only line of text in that file.

Also add this to config.txt: dtoverlay=vc4-kms-v3d.
Insert it on the line below initramfs pinn.rfs
(It doesn't really matter as long as it is not after the [pi4] section.)

Now try booting it in your Pi5 and let me know how you get on.

I reimaged. It booted ok to another HDMI.
I made the change you suggested and tried to boot. It died with a kernel panic - UFS: UNable to mount root fd on unknown block.
I will go back to the beginning and reimage and just change cmdline.txt.

commented

Ok. Got it working on the last attempt.

  • Imaged a 256GB card with pinn-3-8-9-beta.img
  • System has an NVMe. Set boot priority to SDCard
  • Connected and external HDMI viewer
  • Booted and let it do the initial configure
  • Turned it off. Edited cmdline.txt on a Windows 11 VM. This would not work on macOS.
    • Appended video=HDMI-A-1:1024x600@60 to its single line as originally suggested.
  • Booted system to the attached Roadon 1024 x 600 monitor and it worked.
    Now configuring the various OSs I want to try.

Thank you. Not sure why the cmdline.txt edit did not work the first time. Bu I did not follow this process.
