Re: [hatari-devel] EKO System crash

[ Thread Index | Date Index | More lists.tuxfamily.org/hatari-devel Archives ]


I've tested EKO System and it worked perfectly from beginning to end with the music all the time.

I'll relauch it a few more time to check if there's no more sound crash or if this problem is fixed.

The final music (greetz part) is a bit glitchy but sounds correctly.

Hi Thomas,


AFM is still working as before (I mean perfectly except when I select the equalizer which produce a glitchy sound. This was here before your patch and I suspect a DSP problem I'll try to solve one of these days.


Thanks for the "EKO demo patch". That should be also useful for F1 racing.

But with the latest versions of hatari, I had the tridi part music.

In fact, sometimes I have the full music in the demo, sometimes the music "crash" in the first part and comes again at the beginning of the tridi part (the demo resynch the crossbar for the 2nd part of the demo.

Maybe related to accuracy speed of the falcon emulation and crossbar DMA addresses feeding.

Regards.

EKO Systems:  perfectly works (except a little transition in the

        Music plays well until the 3D scifi scene and plays well
again in the tridi world.
Close to end I got Hatari crash:
-----------------------------------
WARN : crossbar DMA Play: Illegal buffer size (from 0x0d84e8 to
0x0d84bc) Segmentation fault
Looking at the crossbar code, I noticed that this could happily read
from beyond the STRam[] array if a Falcon program like EKO system set
the DMA start address higher than the end address.

I've changed to code a little bit so that this should hopefully not
happen anymore, i.e. I hope it also won't crash anymore (though I was
not able to reproduce the crash here).

As a bonus, the music should now play in the 3D racing scene of the
demo.

Note: I've also updated the recording function accordingly, but I did
not test that part. Laurent, could you please try whether AFM still
works fine for you? Thanks!
