!ADFFS crashes system

The last 2 releases of !ADFFS on packman have resulted in my RasPi4B running RiscOS 5.30 crashing when ever it is launched, basically my screen goes grey and nothing except a Ctrl+Break works, which will invariably reboot the system.

Has anyone else experienced this or have any ideas on a course of action to find out the issue or how to troubleshoot.

Usual thing to check is the exact installation instructions here: https://forums.jaspp.org.uk/forum/viewtopic.php?t=665

Although having said that, it looks quite straightforward these days… just use 5.30, and you should be good. How recent is your Pi firmware?

Andrew, if it’s crashing on a grey screen that sounds like something has crashed when ADFFS registers its video driver.

Could you try a couple of tests:

1. Bypass the boot sequence (hammer ESC during boot) and then load !ADFFS without loading any other apps
2. Shell out of the OS (CTRL-SHIFT-F12 twice), manually run !ADFFS and see if it crashes

If the former resolves the crash, what apps are you loading during boot?
If the later loads without a crash, try going back to the desktop via *Desktop

Jon,

Option 1, !ADFFS runs fine, at Boot I am running !IrisRAM, !Organiser and !GeminsGonfig (as using the Module to load Geminus results in RiscOS failing to boot, and goes to the command prompt)

Based on you saying !ADFFS loads its own graphics driver, I’m guessing its !Geminus that is the issue, as it is intercepting Video calls, and sitting between the graphics driver and the WIMP.

You could try loading !ADFFS before Geminus in the Config boot order. Perhaps Geminus is hanging when ADFFS registers its video driver? I’m afraid I’m not familiar with what Geminus is or how it works.

Try bypassing the boot sequence, load ADFFS and then load Geminus to see if it hangs. I don’t have Geminus to check if it installs a GraphicsV driver and if it does, if it’s been implemented as per the documentation. There was a similar issue with the PineBook/Pro GraphicsV drivers last year, where they assumed they were the only GraphicsV driver and would hang in exactly the way you describe.

If you can pin down which app is conflicting, I’ll investigate and either modify ADFFS or raise it with the App developer.

I’ve set up !ADFFS to be the first to be loaded by Run in the boot order, from the config screen.

It results in the grey desktop, and I have to ctrl+break to reboot the machine and “esc” into the non-configured desktop, and move !ADFFS to be able to boot successfuly, so !Geminus is definitely doing something, as removing !Geminus from my boot, !ADFFS works as intended.

I’ll email the developer and see if I can find what’s causing the issue.
