ramlib_PPC data access exception

[Vincent]

When I try to use any PPC software I get the following:

PowerPC Data access exception (load operation)
Memory protection violation - Access to 00000000
The excepting instruction is located at 54A8AC90
Task name: 'ramlib_PPC'  Task address: 54B035C8  Task ID: 112


There's a hex dump after that.

Any ideas how to solve this?

I can post the hex dump if need be, but as it's all letters and numbers I thought I'd ask to save the bother ;-)

Oh, it's a 603e/175MHz and 040/25MHz with 96MB ram.

I've installed MMUlib, but now I can't get a display on my BVision, CGXMode in the Prefs won't work and there are no BVision modes in ScreenMode prefs either.

--edit--

Problem solved - had to add <>NIL: to the BPPCFix line

[Vincent]

Ok, I'm using the RamLibFix at the start of the startup-sequence (I can't find anything about it in the docks) and I still get the error.

put the ramlibpatch, after the SetPatch.

Done, but still no luck :-(

[Vincent]

Anybody have any more ideas?

Please say you do :-)

@Patrik

Yup, still get the error.

I have 2 fans in there now, an old PSU fan extracting heat out through the 3.5" drive bays and an old P500 fan cooling the 040 and ppc, I can't see it being heat related.

--edit--

There is also the original ppc fan on the board (the p500 fan is on the cooler/040 side and the original fan on the other).

The errors come up right after a cold boot after being switched off for 24 hours, so I'm pretty sure it's not heat related.

[Vincent]

I haven't installed anything, that's the strange thing.

The only thing I've done since getting it working was change screenmodes of progs to use the bvision, that was it.

I spent most of the time playing ArTKanoid ;-)

DoomWOS is working now, but anything else that uses the PPC comes up with the same error (W3Ddemos, Quake, Payback)

[Vincent]

Okay, tried your settings (deleted my CyberGraphX, PowerPC and Warp3D dirs and copied yours over).

No change, DoomWOS still works, everything else is up the swanny :-(

[Vincent]

Problem solved (well, the Warp3Ddemos work so I thought I'd post with what I did asap before anything else happens ;-) )

Checked out my libs dir and I had the following in Warp3D:

GFXDrivers
W3D_CyberGFX4.library - 40,292 bytes - version 4.2
W3D_CyberGFX4_PPC.library - 16,128 bytes - version 4.0
W3DPicasso96.library - 38,664 bytes - version 4.2
W3DPicasso96_PPC.library - 20,508 bytes - version 4.2

HWDrivers
W3DPermedia2.library - 579,708 bytes - version 4.2
W3D_Permedia2_PPC.library - 502,980 bytes - version 4.2

Now, in my backup (created as soon as the BPPC and BVision were installed and working) I had:

GFXDrivers
W3D_CyberGFX4.library - 38,996 bytes - version 4.0
W3D_CyberGFX4_PPC.library - 15,412 bytes - version 4.0

HWDrivers
W3DPermedia2.library - 93,120 bytes - version 4.31
W3D_Permedia2_PPC.library - 396,812 bytes - version 4.2


Notice the difference?  Mainly in the filesizes of the HWDrivers dir being ~700,000 missing

God knows what happened (or what installation, or me getting libs from Karlos to try Quake stuff...), but it seems to be happy now :-)

[Vincent]

I suppose I should've stated the first list was the "current" (non working) libs, deleted and replaced by the backup ones (2nd list).

@Karlos

I'll try chucking the 4.31 lib back in later on... once I've had some fun in Quake ;-)

I still say it is a heat issue.

It's been working almost full time since getting it fixed on the 19th with only a few software errors (unrelated - I'm trying stuff out).

The issue was with the libraries themselves.
