Re: Minimig (Amiga) core discussion

Nope. If it works with one core then it should work with other. Okay, then I must have incorrectly built the execution environment or something is wrong with the 32MB SDRAM. 1) If I ran the memory check for 2 hours with no errors does that guarantee that the full 32MB of RAM is present and error fr...

Re: Is a Dreamcast core possible

I don't think its possible. I'm not a programmer but I looked at some specs myself. As far as I know the MISTer Cyclone can have up 50Mhz and someone said it may be pushed up to 100Mhz by doubling it somehow. The Dreamcast has far higher speeds. Maybe a Hybrid Core can be made. In Theory. up to 50M...

You need to use tool to prepare the SD card and put MiSTer system files there.

You cannot simply format SD card and use.


Is that specific to Minimig? The SD card works for Mister and Galaga.

Re: Minimig (Amiga) core discussion

I don't think it's a hard drive problem. All I'm trying to do is boot a simple Workbench 3.1 Install floppy. Maybe there's some wierd bug in the A1200 implementation. I should probably try going all the way back to a basic A500. Well, test #15. I tried the simplest possible setup I could think of. ...

Re: Minimig (Amiga) core discussion

wait, so can you even boot the minimig core? if not, have you tried another core like the mister menu? Yes. I mentioned that in previous posts. The DE10 with 256MB slim memory card: a) Passes the memory tests for 2 hours straight with no errors at 167 MHz. b) Runs Galaga just fine (except for some ...

Re: Minimig (Amiga) core discussion

I suggest to start to use Amiga with floppies first. Actually most games work from floppy. HDF files created in UAE aren't always compatible. As explained earlier it's highly suggested to initialize and format the HDF on MiSTer first and only then use it on UAE to fill with required apps. Okay, so ...

Re: Minimig (Amiga) core discussion

Thank you wins and sorgelig. That might be one of the only things I didn't try. Hard to remember because it was getting very late. Boot into a 3.1 Workbench floppy image directly.

Re: Minimig (Amiga) core discussion

I've got my mister running. It passed 2 hours of memory tests on the 32 MB slim memory card I constructed at 167 MHz. It runs Galaga just fine, even without a memory card. Unfortunately I spent several hours last week trying to get Minimig to boot, but had no success. I loaded the latest Minimig.rbf...

Finally...

A newborn 32MB Amiga is about to be loaded up. All the time waiting for little purple board, buying the parts and soldering. Thanks Sorgelig for the fantastic work. I'll admit that I was sweating through the slim 32MB memory board. I have a great soldering iron and watched the drag soldering videos,...

You've asked about time out in released cores - i've said there is no timeouts there.
Compilation and licenses are completely different things. End user should not worry about this.

Oh ok.

In the core porting doc it says there is a timeout if you don't have the full development license.

Also, does HDMI still take a long time to compile?

Re: I/O Board

Is one of the primary reasons for the IO board to circumvent the one hour timeout on the HDMI and scaler IP from Altera? I believe the other one is that the HDMI IP also takes a lot of space and compile time. I guess I could also just plug into my monitors VGA autoscaler port... not many have those ...

DE10 Nano LTC 2x7 Connector

I've been trying to find a suitable ribbon cable for the 2x7 socket labeled "LTC 2x7" on the DE10 to do some hacking. I have a 2.54mm 2x7 ribbon cable but that doesn't fit. I think it must be a 2mm IDC socket. DIGILENT sells a 2mm 2x7 IDC JTAG ribbon cable for Xylinx boards that looks corr...

Re: RTC board

Okay. I see. The date-time service just formats the Linux date/time and passes it to the Minimig core, so you only need to change the Linux driver to support the new RTC chip. right. But i strongly suggest to use recommended chips. They are not hard to find and there is board already for them. Othe...

Re: RTC board

There is no book of documentation if you mean this. You can check hps_io.v signals. There you will find RTC info. It would be more clear if you would tell what you want to do. Are you writing core which needs RTC? Ok, thanks. I was wondering what would be required if I wanted to use a different chi...

Re: RTC board

Sorgelig, I was studying the RTC board and I'm trying to figure out how it works with the Minimig core. Obviously the M41T81 communicates with the Linux side via I2C. It updates periodically and via the hwclock command. How does the minimig pick up this date and time? Does it have direct access via ...

KEMET C0805C104J5RACTU Unfortunately everyone seems to be out of them right now unless I want to buy 4000. I looked on mouser and there's a very close match made by KEMET, ...
