TOS RAM test routine ?

[exxos]

With STE TOS206 ST536 TOS it does show up the STram test. But it does not see the TTram

I think it keeps on turning on 24 bit addressing by itself which is probably why

If I changed the header to 209 it just freezes then

Use my fixcrc program to fix that.

Never thought of that...

Though generally TOS doesn't lock up completely after failing the CRC test.. Unless something else funky is going on

EDIT:

Saying that it won't help.. As soon as Hatari sees "2.xx" it switches on 24bit addressing

I think someone mentioned this could be disabled in Hatari last time I was messing with it all.. with the usual "if you compile it yourself" type of "help"

My fairly heavily modded Hatari oddly prints the dashes without reverse text then bombs at the start of the TT-RAM test.

With memvalid it just bombs early doors.

No bus error logged in the console, which is odd.

So you know how to do mods to Hatari then ? If that's the case if I could find line of code which has mentioned you could probably just remove that for me ? I would assume if it stopped switching to 24bit addressing then it would allow TTram to work ...

Yep, just found the line & nixed it.

tos.c:

Code: Select all

	if (ConfigureParams.System.nCpuLevel < 2 || (TosVersion < 0x0300 && !bIsEmuTOS)) {
			ConfigureParams.System.bAddressSpace24 = true;

TT-RAM test is slow as molasses, as described.

argh, how many seconds did it take you to do that ? GIMMIE!!!

I only just found the email about it

Have a look at tos.c :

/* 32-bit addressing is supported only by CPU >= 68020, TOS v3, TOS v4 and EmuTOS */
if (ConfigureParams.System.nCpuLevel < 2 || (TosVersion < 0x0300 && !bIsEmuTOS))
{
ConfigureParams.System.bAddressSpace24 = true;
M68000_CheckCpuSettings();
}

I think it should work if you change the 0x0300 into 0x0200.

You could just change the TOS header to read 3.06 instead.

That's what I mentioned earlier.. It just goes to desktop without doing any RAM tests

I'd been hacking that file already for my own nefarious ends.

I'm afraid a debug Linux version is probably not much use to you.

That should work -- isn't that where we came in?
