MiSTer FPGA Forum

I am trying to run MiNT and Xaaes with 8M ram. I get corrupted paths. With 4M it works (but very limited after aes and teradesk is started). I have tried with two boards and ram modules.

Have I missed something that I can configure? I have a diskimage that works with 8M on hatari STe but not on MiSTer (STe 8M).

Looks like this at boot time:

Which TOS version do you use? 8 MB Ram was always something that could only achieved with tricks on a real machine and I am not sure which path the Mistery core takes here.

It is the very same, strange problem I've expirienced a few month ago with my Suska III-C board. i will file a bug torwards the devs. Is it ok for you when i link your post here?

Edit:
My first bugreport ist still open: https://github.com/freemint/freemint/issues/216

I have tried all kind of TOS. I think that tosemu 256k works best.

Have you been able to solve the problem in the meantime?
I have exactly the same problem.

Me three, also basic exact the same problem. I made a Mint vhd file and this works on Hatari at 8MB or 14MB, but with Mister it dies as described with any memory above 4MB. 4MB it's fine, 8MB + it dies at xaaes.km. I wonder if Mister is implementing some limitations of the original Atari STs and the 4MB barrier. TOS version doesn't matter. tos162 or etos both exact same results.

For both Hatari and Mister if I set chipset to MegaSTE neither work. Hatari just soft locks and Mister throws an error, so maybe that's a Mint bug.

And superficially, Mister looks like it should be okay. Sets this extra_ram for 8MB or 14MB
.extra_ram ( MEM8M | MEM14M ),

And then sets dma bits 23,22 if that's set.
if (!wdmah) dmaa[23:16] = id[7:0];
if (!extra_ram) dmaa[23:22] = 2'b00;

I have it working with 14MB in miSTer, or am I missing the point? See Screenshot...

I am using a HD Image from here: https://subsole.org/st_mint#with_an_emulator Surley not the latest. Latest EMUTOS, but also works with TOS 1.62 AFAIR. Its just running, haven't ried any apps apart from the ones on the desktop.

I grabbed that st_mint-1.3.img from that website, renamed to st_mint-1.3.vhd, (that's all I have to do, right?). I matched your config exactly, even went to etos512de.img 1.1.1 (even though my high school German is super bad) and it's still crashing. Something weird is going on here.

Oh and I did get it to load, like twice. I think it's just random.

Yeah, seems so. Sometimes it just does not work…
