FPGA Replay Board

[bbond007]

I have the file and it is about 10GB large (the hardfile). It works nice on WinUAE though -- as you also probably have tried. Yet, I would have to shrink it a little down to fit my 8GB SDIO card to test on the Replay first. I will bring it home and try and see if it works. It boots up a plain OS3.1 with WHDLoad on it and a ton of games/demos -- so I think it will work pretty nice. Just have to test it first

Thanks for that link. It'll be a nice baseline for my new hardfile

unless that is a newer version of that same hardfile, it expands out to a 8GB HDF (too big for FAT32), however its less than 1/2 full so I was able to copy everything to a 4GB hardfile that worked on my Minimig 1.1.

And I received it..

It's an LC version, and it's soldered to the board. No go unfortunately. I guess I'll have to put my faith in MikeJ's angels and their awesome 060-hunting-skills

060's are pretty hard to find in large number of stock (at least in Shenzhen) and all the ones I've came across are 2nd hand I dont believe there is any NOS for such a old CPU.. On top of that theres the temptation for resellers to shave off the tops of lower CPU's and relabel them as 060's..  Wish Mike the best of luck it certainly wont be easy and challenging..

Build a portable '060' tester?

yeah you would definitely bring along something to test the CPU with..  even if you ask your dedicated chinese reseller, they will always listen to what you need, then buy it from another reseller for you so 060's will come from alot of different multiple sources..

The Replay board itself is a portable tested, I am trying to get a ZIF socket for the processor.

The mask revision is contained in the PCR register, does anybody know what this register should contain for each mask set?

there doesn't appear to be any documentation on revision, but from a quick google.

switch( (PCR >> 16) & 0xffff)
{
case 0x430:
   printf( "MC68060\n" );
   break;
 
default:
  printf( "MC68LC060/MC68EC060/something else\n" );
  break;
}
 
switch( (PCR >> & 0xff)
{
case 1:
printf( "1F43G\n");
break;
 
case 6:
printf( "0E41J\n" );
break;
 
default:
printf( "1G65V/2G59Y/something else\n" );
break;
}
 
revision 6 appears to be the golden one. if you google 68060 revision 6 then everyone goes mental for it.
afaict only full 68060's were availble as revision 6.

Quite right, even though the filesystem supports fat32 the Amiga os may be an issue.

The FAT32 has also 4GB file size limit.

[Darrin]

The FAT32 has also 4GB file size limit.

On your daughterboard design, will the card reader on there have the same limitations?  Would it be possible to use use 2 x 4GB HDF files via the FPGA card reader and another 2 x 4GB HDF files on the daughterboard card read to have 4 x 4GB "hard drives" available to Workbench?

Using the daughterboard USB, would it be possible to mount a large (>4GB) external USB hard drive using SFS or PFS3?



Edit:  Where did all of those typos come from???!!  I ned a knew ceybord!

No, the daughterboard card reader is visible as Amiga hard drive and not as hard file emulator. You can format it with whatever filesystem you like. The limitations are imposed by filesystem handler you use.

Yes, USB host controller uses Poseidon USB stack so it is the limiting factor.

Excellent.  So in theory I could put in a 20GB card and format it as a single 20GB PFS3 drive or a 2GB FFS and a 18GB PFS3, etc?

Meanwhile HDF files on the main FPGA board's card reader will still be available to mount?

Yes, USB host controller uses Poseidon USB stack so it is the limiting factor.

Excellent.  Having used Poseidon for several years now, it is a great stack and I'm glad we'll have it on the FPGA Arcade.  The expansions options it will add will be almost limitless.

Yes. But there are FFS versions which support partitions larger than 2GB (OS3.5 or 3.9) so you could have one 32GB FFS partition.

Meanwhile HDF files on the main FPGA board's card reader will still be available to mount?

Of course.

Exactly. I wonder if dedicated micro SD card reader is necessary because an USB micro SD card reader connected to daughterboard USB port reaches transfers over 13MB/s.

True.

I would say that if it doesn't add too much to the overall cost then the micro SD card is handy to keep the main components "all in one box" rather than forcing you to lug an external drive around have have one clutter up the desk.

From my A4000 point of view, I still use internal hard drives rather than an external drive attached to the USB port which relies on my correctly flashing the ROM on my Deneb for it to be detected at boot time or hoping that the USB stack doesn't go "tits up".  I assume this will be a similar case with the micro SD card and it will be immediately available to the system to boot from.

The FAT32 has also 4GB file size limit.

Yes this is true. Possible to span a virtual disk over multiple files?

[freqmax]

Maybe time to consider another filesystem than FAT32 ?

UFS perhaps?

[gaula92]

Maybe EXT3/4 would be a better option. It's (in my experience) faster with many small files than UFS.

[Dopuser]

Mike I am also interested in replay board + daughter board + 060!

BTW: what is estimated price of full set, including replay board + daughter board + 060?
Any expected time of availability?
