    I guess the PFS problem is either a Cor or Path problem on Kickstart

    I have Minimig, Mista, Mister and there is no problem tutal it is enough to create a partition in PFS after the restart (SD boot attempt) causes guru
    Error 8000 0008 Task 0202A68 this problem does not occur in other Mist / Mister / Minimig systems and in real A600 / A500

    Guru failed to get PFS partition not detected.
    "TD64 Read" and "HD_SCSICMD Read (10)" are and are working.
    The same card under UAE works, so I think I set up the partitions correctly.
    I do not know...

    For me, after creating a partition (WinUAE / Is DIY-A586) and loading FS pfs3aio 0x50465303, both LEDs light up red guru and reboot and over and over again when I change the type to FFS everything returns to normal, under WinUAE everything works OK. CPU 00 / FullECS

    PFS3AIO can be loaded manually via mountlist, automation doesn't work yet.

    As for PFS, there is improvement
    No automount guru doesn't work yet :)

    I noticed one more error when I set up next partitions (no matter if PFS / FFS), mimi that I change the name to DH1, DH2, etc. in the program shows ok but in Workbench, for example, with CLI after assigning it is DH1GE_ME DH2GE_ME as if it did not delete characters
    It's OK under WinUae

    Look for a ROM with MD5 = "e40a5dfb3d017ba8779faba30cbd1c8e"
    It won't work with another.

    Is there a minimum chance to accommodate this FPGA support for the 68020?

    I still have a question if there is a chance to design an amiga splitter board on a different chip like the PIC16F15313 or at least in a housing other than smd. Currently, in Poland, PIC16F15313 on SO8 is bordering on a miracle (you would have to import from the states) and the protracted version can still be bought somehow. Possibly, the version on the atmegas that there is a lot on the market would also solve the matter (but here you would have to tinker with the software again and I suspect that the redesign of the board just to replace the chip with another socket would be simple.

    Someone may enlighten the question as to the validation of the system

    I have an SD card, I installed everything on WinUAE, everything worked fine, but after switching to the read error HDD disc
    It's OK again under WinUae

    0.1%
    FPGA too small.

    @shafty
    Must be PIC16F15313 because of the programmable mini logic it contains. The slinger itself is not used.

    but after translating to the board read error HDD

    Workbench error?
    Use some disk editor to see what the first sector of the card looks like.
    Or you'd better create a small image (~ 16MB) and send it.

    OK, I am already correcting and testing further
    I forgot my PFS error



    I'm testing and I have a question
    I assume partitions, I set max transfer, I save (reboot)
    I fire up HDToolBox again, go inside and there again max transfer 0xFFFFF
    Is it supposed to be like that?

    Did you confirm the value after typing?

    Is there any keyboard shortcut (A + Ctrl + A)?

    Added after 9 [minutes]:

    OK. I put everything on a new one
    Checked 1FE00 for each partition set

    And after the reboot, anyway
    Workbench has read error

    New file for test

    Reset by push button only.

    I have just tested the workbench card installed under FS-UAE (linux) and everything works. I created partitions on DIY-A586.
    I don't know, I have no idea what could be wrong.

    Loading even a little or immediately error?
    Have you tried with one small partition? Let's say 256MB.

    OK. I will test it on a small one
    I think I found a problem
    This seems to be a problem after mounting PFS
    I will wait for PFS autoounting etc and for now I switched to FFS

    Ok clear must be the PIC. Only if it could be the same PIC, but in a different housing. There are at least two stores where I can buy PIC16F15313 through-hole and not one where I can buy SMD.

    Or something else. Can I replace it with a PIC16LF18313-I / SN processor?

    No, not enough CLC.
    It must be PIC16F15313, any housing.

    RS works like a dream, connected with 3 wires to mikrotik, PPP / COM server there.
    Miami setup and everything works fine.

    Way to go!

    I postpone the card. And when I created the partition, I don't remember it anymore. I think I used a virtual machine.

Topic summary

✨ The discussion revolves around the DIY-A586 v1.6, a retrocomputing emulator designed by Piotr Go, featuring an FPGA Spartan6 XC6SLX9, 8MB SDRAM, and various connectivity options including HDMI, RS232, and joystick ports. Users inquire about programming the FPGA, configuring floppy drives, and compatibility with different ROMs and cores. The author provides updates on core development, including support for Amiga and PC emulation, and addresses technical questions regarding component specifications, programming methods, and troubleshooting issues related to SD card usage and floppy drive connections. The conversation also touches on the potential for future enhancements and additional cores for other systems like C64 and Atari.

FAQ

TL;DR: DIY-A586 packs a 100 × 100 mm Spartan-6 board that stores 30 FPGA cores in its 16 MB flash—“Up to 30 configurations in flash can be loaded” [Elektroda, piotr_go, post #18067213] Why it matters: one card swaps instantly between Amiga, PC-XT, C64 and more.

Quick Facts

• FPGA: Xilinx Spartan-6 XC6SLX9-2TQG144 [Elektroda, piotr_go, post #18067213] • RAM: 8 MB SDR SDRAM @ ~56 MHz (Amiga) or 133 MHz CL2 (PC) [Elektroda, piotr_go, post #20583795] • Flash: 16 MB SPI (Winbond 25Q128) — first flash needs external programmer [Elektroda, piotr_go, post #19143673] • Power: 5 V via USB-C; legacy floppy drives need extra 12 V rail [Elektroda, EKBubba, post #19358582] • SD: SDHC (≥4 GB) FAT32 + Amiga RDB, multi-disk driver v0.10 [Elektroda, piotr_go, post #20677771]

What components are mandatory for a working v1.6 board?

Essential parts: XC6SLX9 FPGA, AS4C4M16 SDRAM, Winbond 25Q128 flash, 16 MHz CMOS oscillator, SD socket, USB-C power jack, two SOT-223 LDOs (3.3 V & 1.2 V) and the HDMI level shifters [Elektroda, piotr_go, #18067213 #19178403].

Which SDRAM speed grade should I order?

Any 166 MHz (6 ns) IS42S16400J will run; Amiga core clocks the RAM at ~56 MHz and the PC core at up to 133 MHz CL2 [Elektroda, piotr_go, post #20583795]

My SD card isn’t recognised—what’s wrong?

The driver needs SDHC cards; old 2 GB SDSC cards fail detection [Elektroda, piotr_go, post #19186591] Format the primary partition FAT32 (MBR) and place *.A586 files in the root.

Can I use PFS3 or multiple virtual hard disks?

Yes. SD.ROM v0.10 adds multi-disk and PFS3 support. Each MBR primary partition type F0 becomes an Amiga unit; FAT volumes stay readable via fat95 [Elektroda, piotr_go, post #20677771]

How fast is the new Mikan 0.1.7 Amiga core?

It delivers ~143 % of real A500 CPU speed and triples SD throughput versus Minimig; audio, bitplane and copper bugs fixed [Elektroda, piotr_go, post #20783590]

Does Gotek or dual-drive work?

With Mikan v0.1.5+ the auto-switch logic makes DF1 the boot drive when it asserts _RDY during reset. Both drives must output _RDY and DF1 should be an emulator that ignores _MTR [Elektroda, piotr_go, post #20677771]

Edge-case: Amiga mouse and PS/2 mouse together?

From Mikan 0.1.9 you may connect either two Amiga mice (joy ports) or one PS/2 mouse; mixing beyond these combos is unsupported [Elektroda, piotr_go, post #21362045]

Why does my vintage Chinon floppy spin but not read?

Early 720 kB drives and A500 units draw 12 V for the spindle, which the DIY-A586 5 V rail can’t supply. Feed 12 V externally or use a modern 5 V-only mechanism [Elektroda, EKBubba, post #19358582]

How do I patch Kickstart 3.2.1 for SD boot?

Run the supplied xdelta script in mikan/kick3.x patch v0.8 then rename the output to KICK32SD.ROM and list it with -fb in bin2a586; checksum must match 75c85b… [Elektroda, piotr_go, post #19898942]

What’s the licence situation—why ‘DEMO LIMIT, 4 CORES MAX’?

Unregistered MAIN limits the flash menu to four cores; request a free personal key from the author via forum PM to unlock [Elektroda, tchernychov query #21048193 and piotr_go reply context].

Where can I source the 16 MHz oscillator?

Use any 3.3 V CMOS clock module, e.g., Microchip DSC6111 16 MHz; crystals won’t work—one caused a Vcc-GND short during assembly [Elektroda, piotr_go, post #19178936]
