Scratch3 doesn't work on Pi5 with 16KB pages

[lurch]

As spotted on the forums https://forums.raspberrypi.com/viewtopic.php?t=357782

I tested all combinations of Scratch 1, Scratch 3, Bookworm 32-bit, Bookworm 64-bit, Pi4 and Pi5. Everything works fine except for Scratch 3 on 64-bit Bookworm running on a Pi5 (as noted in the forum, it results in a Segmentation fault when run from the Terminal). Seems strange that it works on 64-bit on Pi4 but not 64-bit on Pi5!

You could try with kernel=kernel8.img in config.txt, so the Pi 5 is running exactly the same kernel as on Pi 4. Without this the Pi 5 will use 16KB pages.

Ah yes, that indeed gets things working :+1:

Title updated accordingly.

Scratch 3 not working is a known issue and the Foundation are already working on it. I believe I mentioned this in the launch blog post!

Although now I check, I didn't, probably because at that time it didn't matter, as no-one had a Pi 5. Anyway, as above - know issue, Foundation already investigating.

@SivaVasudevan0204 create a new issue. Your issue doesn't fit the title "Scratch3 doesn't work on Pi5 with 16KB pages", so is just confusing this issue.
