Re: TOS RAM test routine ?
:WTF: Hatari 1.9.0. I set 64 in the cfg file. It refused to show the TTRam bar until I restarted it just. Capture.PNG 1.PNG So putting 10 in TTram size gives me this :shrug: Capture.PNG Does anyone know if there was more " nightly builds" of Hatari 1.9.x ?? I mean it jumps to version 2.0.0...

Re: Atari STE with T0 and e7 spurious interrupt
Pin 93 is from the MFP to request the interrupt, I see there is an ack pin too... Worth checking :) gst-mcu.jpeg Indeed. The simplest thing I think it is to remove the MFP and see if the IPL lines go high ( after checking they have the pullups of 10K on them). If they do go high then it would appea...

Re: Atari STE with T0 and e7 spurious interrupt
I did just check pin 32 on the MFP and it is active low, which is what it should be (IRQ Output) I assume if making a request to the GST. So seems stuck making a request? There are no components between the MFP and the pin on the GST, just a few VIAs, and it measure .5 ohms without power pin to pin...

Re: Atari STE with T0 and e7 spurious interrupt
The block diagram below sounds like the MFP may make the interrupt call to the GLU but never passes the vector info for the interrupt and the GLU passes it through only the interrupt request? Is it still possible the MFP is defective and not the GST MCU? I guess you could change the MFP. But if you...

Re: Atari STE with T0 and e7 spurious interrupt
Have you checked they have pull-up resistance such as 10K to 5V ? Checked they are not shorted to GND ?
Indeed I am not overly sure about the interrupt lines but I don't think 2 should be low at once like that. But could suggest the GST may be buggered at this point.

Re: TOS RAM test routine ?
Finally found a version of Hatari which works. 2.0.0. So for whatever reason TOS306 has 1min 20seconds for 64MB and ST536 TOS takes 2mins 25 seconds. So with this config now I have something I can work with. EDIT: So 206 turns on 24bit addressing and changing the header to 306 it crashes FFS!. Capt...

Re: TOS RAM test routine ?
I found this code which seems a little odd as well. Though possibly this could be a different memory test routine.. The whole thing is frustrating.. Does anyone know how to contact any of the Hatari developers to see if they would build me a custom version with the 24bit thing removed ? #if (TOSVERS...

Re: TOS RAM test routine ?
So I guess it should have been #$00000001 then Badwolf ? I can change it. But I don't think it would make any odds. If 306 is doing it that way then probably does not make any odds at all anyway. I think it would be happier just having it as instruction only.. I assume it would change to both enable...

Re: TOS RAM test routine ?
Runs the same speed as before, but yes, CACR is now set to 0x3111 (both caches enabled). This seems odd to me (why data cache when testing memory?) but it's like it under TOS3.06 and I suppose if you're scanning everything once the cache will miss all the time anyway. So this ought to be faster on ...
