I currently do not have a board to run this project on.  Should I get the more
expensive DE2
or is the DE1 fine?  How much FPGA space does the current implementation use? 
I'm new to
all this FPGA stuff, but it sure looks fun!

Thanks!

Hi,

Can anybode recommend an easy way to create the daughter board for
connecting the mouse and the joystick?

The Fampiga runs fine, it runs the same demos as the 12c version.

greets,
Sander

Hello,

Sorry I overlooked the source files. Compiled the new version and tested
Little Computer People, the program starts but still testing the write
to floppy. I also added a new file for the PS2 keyboard routine, I
eliminated the Numlock function for very small keyboard.

Hello,
I checked my setup again - and it works with the .pof and with
the .sof that i have published.
Please reformat your SD Card copy the files and try it again. The
new spihost.rom has only effect with the new config file. If you use
the new spihost.rom and the 12e config file is the adf Image always
write protected.

Hello,

I use the pof file from v13 to check, after I flashed the DE1 the
minimig does not start. I checked again using the 12e version, this
works. As test program I will use little computer people (it stop after
a while when it want to write change to the adf).

Tell me more about your Problem, Please. You must use the new
spihost.rom firmware and the minimig_de1.sof to config the 2c20.
The are only little changes between v12e and v13. Look into the
minimig1.v file and the bigrom sourcecode.

Hello,

I tested it with the new spihost.rom, but it does not work. The new
spihost.rom works in the 12e version. Can you release the part you
modify in source, to recompile version 13?

Hello,

i have done it a year ago. Based on Tobiflexs DE2 Code.
You can download it from:

http://drunken.intershit.com/cpctrex_DE1_Port1.rar

So far no SD card and no sound output ...

On http://www.amiga.org riftcon, piru and i discuss about the 68sec000.
Now it look like the 68SEC000 is a 68000. The "Move from CCR" is
illegal and "Move from SR" is not privileged. What's matter with the
68EC000 we don't know. We must find somebody who can test it with a
real 68EC000.

Now I say: the 68SEC000 is a good choise for the minimig.
But the TG68 is also good and you can clock the TG68 higher.

It isn't a new 68K Core. But I use only the kernal of the tg68 Core.
The Screenshot is made with a DE1 Board. But the is not a 68020. It
is a fast 68000 :-)

Wow!!!

Your work is impressive! :-)

Even if SysInfo is not the best Amiga benchmark I guess that your core
gives more accurate speed than emulators... so it's really fast! It
would be interesting if RedSkull could test your new 68k core on a
DE-1 board and report results...

I'm curious... the new core works as an asynchronous accelerator on A500?

68020 emulation probably wouldn't be impossible so I guess that an
entire A1200 could be implemented in the future with the same hardware
(I think gfx capabilities of DE-1 board perhaps won't allow 24bit
colours but it would be cool anyway...)

Could you sum up the requirements for the minimig SDRAM access?
(operating frequency; maximal latency: data width.. )

Sorry for noch checking the Minimig sources for myself....

One (other) obstacle you'll face in using another DDR controller in Minimig
is that the controller needs to arbitrate between 68K and Z80 accesses - so
you'll notice there's two bus interfaces on the Minimig controller.

The Minimig does the arbitration within the controller itself, but I guess
there's no reason you couldn't do it outside the controller and leave it
unchanged - much like the arbiters in Altera's SOPC system. Some time ago I
wrote a simple arbiter for wishbone based on the example in the old wishbone
documentation...

I'm actually the author...  and I've seen some examples of it being in
use :)  None of them was actually small...

But it does present you a well documented wishbone interface without
bells an whistles, not even burst transfers. I've had a positive
feedback from someone using it on a Spartan-3E 1600 Starterkit without
any tuning or twiddleing...

The biggest obstacle shows up when you change the operating frequency
and need to readjust the phase-shift between the reading and sending
side: it does not auto-calibrate :(

You are correct! It is DDR-memory and the 1600 is a "bigger brother"
of the more common 3E-Starter Kit with its 500K-device.

Thank you for the tip about the DDR-controller. I've seen it but I
would really like a good example of it in use.. Have you seen some?
I'm used to working with SRAM so if it only could be just as simple..

Digilent seems to have removed this board from its page -- so I can't
verify: But isn't this board the big brother of the Spartan-3 500E
StarterKit? I think it does use a DDR(1) memory.

I'd expect the verilog memory controller at

    https://roulette.das-labor.org/bzrtrac/wiki/wb_ddr

to work fine on that borad...


   j.

Anyone tried? Anyone working at it right now? I own a Digilent
Microblaze Starterkit and would really like to be able to boot an
Amiga on it. It comes with a Spartan-3 1600E so I think it would be
able to sport the complete solution with bvoth Minimig and TG68.

I've also added my own extension board for it that probably would suit
Minimig perfectly. It adds: 4096-color VGA, SD-Card-socket,
C64-joystick-port, Extra PS/2-connector, Stereo Line-out for sound.

One of the problems I have is thta I'm new to handling the onboard
64Mbyte DDR2 memory so that si probably one obstacle to try and get over..

I've already played around a little bit with the FPGA-64 project and
gotten the C64 to boot and function quite OK. Also managed to add a
SID to it and head some sounds by hacking some POKE's in a BASIC program!

You have done an amazing work :-)

Although I understand that proper sync is prioritary, I'm curious...
could your emulator work in an "async" way and get faster? It would be
a good test to discover if the current core would be enough for e.g.
020/14Mhz emulation speeds :-) And that could help to get more speed
with faster FPGAs... maybe implementing some kind of instruction
"pipelining"...

How is going RedSkulls' ECS emulation?

I have never seen a picture from a minimig with a 2.04 bootscreen.
But the minimigtg68 can boot all versions of kickstartrom.

Now I found a little but important difference in the 68sec000 and the
TG68 IP Core.

The tg68 is a 68000 Clone. But the 68sec000 insn't a 68000 and isn't
a 68010. That is the Problem.

The Move from SR is priviligated in the 68sec000. Kick >= 2.04 use
this Instruction to check the CPU Type.
For the kick 2.04 is the 68sec000 a 68010. But the 68sec000 has the
exception stack frames from the 68000. That can't work without a
patch.

But the TG68 use the Move from sr in user state and use also the
68000 exception stack frames. That works fine.

I think the TG68 IP Core is the better choose for the minimig!

The only issue I think you'll have is the SDRAM controller, as the
configuration of the SDRAM on the DE2-70 differs from the DE2.

I have ported the DE2 to custom hardware with differing SDRAM and it boots
Kickstart and runs the floppy disk emulation menu - although I can't get it
to successfully boot a floppy image. Having said that, I have the same
problem on a DE2 when I build the DE2 version myself as well, so I'm not
convinced there's not a problem elsewhere...

The SDRAM on my platform is larger than the DE2, but the SDRAM controller
appears to handle it because it drives 1 more address line than the SDRAM on
the DE2 requires. I punched it out to the top level and, as I said,
Kickstart boots so I'm reasonably confident that it's refreshing the SDRAM
on my platform correctly...

Every other aspect of the design should run as-is...

Hi people

I'm new to this forum.

I'm a hardware engineer and i bought some Xilinx FPGA
evaluation boards, including and XUP-V2P, for hobby
purposses.
I never worked with Altera FPGA's, and i'm planing to buy a
board from Terasic.
I wish to buy a board to make work Minimig but i wish to buy
a powerfull one that can be expanded in a near future.
I saw on the Terasic web page the DE1, DE2 and DE2-70, for
the price difference of the DE2 and DE2-70, around 100%, i
think that the DE2-70 is more interesting because doubles
memory lenght.

Have tested any of you the Minimig on a DE2-70 board?
Should be easy to syntetise the source for the DE2 board in a
DE270?
I ask this because i doesn't have any experience with Altera
devices until now and i don't know if it will be difficult to port
the source to a DE2-70 pcb.

Best Regards

Xavier Ruiz
