Phase5 Blizzard 2060 problems

[kernal]

I have a Phase5 Blizzard 2060 with a 68RC060 processor in it running at 50Mhz.

My Amiga 2000, which is running OS3.5 crashes at various times after running setpatch. I know what your thinking.... that I don't have the right 68060 libraries loaded. But I have 68060 libraries installed as they should be, but they will only load properly with data cache turned off.

What I have discovered is that if I boot the computers with Caches turned off (selected on boot screen when holding both mouse buttons down). It will boot up fine, although because there is no caches it is extremely slow. Once I am booted up I can use CPU060 (Phase5 utility) to turn on Instruction Cache (an increase from about 5MIPS to 23MIPS) , and it still runs fine with no issues. If I turn on the data cache, it will sometimes crash instantly, other times it will run for a bit and then crash. Even simply moving a window will crash it when data cache is enabled.

I'm now starting to think that the data cache portion of the 68060 is detective. Is this a possibility? Has anyone else seen this problem?

Yes, because you installed the wrong 68060.library and or forgot to install the "dummy" 68040.library wich is obsolet on 3.9 with boingbag 2 but not with 3.5!... the 68060.library of the Blizzard 2060 is not the same as for a cyberstorm 060. Blizzard 2060 came with a different install-Disk! You can use the Blizzard 2060 System Disc from here: http://phase5.a1k.org/ or, as Thomas suggested you can use the MuTools from aminet: http://aminet.net/package/util/libs/MMULib

No, like I said, I have the right libraries and I I have also tried various versions as well. The libraries actually load and show that it is a 68060 etc etc... I have the dummy 68040. Everything works but crashes randomly unless I disable data cache. Also, I have installed the MMULib.

If it is a hardware issue, is it more likely the board itself or the CPU? I was thinking since the data cache is built into the chip I may be able to resolve with a new CPU?

I'm going to have some spare time this afternoon so, if there's any tests you would like me to run, or something you'd like me to check, I'll be free. 

Sure, that would be great. First, for comparisons sake can you run SysInfo and tell me what MIPS your getting? If both your datacache and instruction cache are on you should be getting around 39MIPS. Also, if you could get the version of your setpatch and all 680x0 libraries. You should have a 68040 dummy library (very small) and at least a 68060 library. I think maybe some of the newer setpatches will load the 68060 without the dummy library, but I'm not 100% sure.  You could also run CPU at the in the C: folder and tell me what that tells you...

Thanks a bunch!

P.S.   The card was shipped with an O60 and has all the right components on it...

Thanks giZmo350,

Out of curiosity, what is your MIPS reading on SysInfo4?
