Not an issue. Built one and it's working perfectly.

As stated in the subject, I built one of these, and it's working beautifully.

I flashed oktapussy before soldering the flash chip. The card booted right into WB 1.3, where I was greeted with 8 MB FastRAM.

Thanks @OlegMishin

[OlegMishin]

Thanks for your feedback, @tkurbad !

[rmueller83]

Could you explain what Oktapussy does? Do I need additional SCSI hardware to use this?

[OlegMishin]

Hi @rmueller83, The "Octapussy" ROM contains an IDE driver and some libraries. It shall be flashed to the Flash ROM to allow booting from HDD. Seems the ROM has also a memory driver as the 8MB RAM detected even in WB1.3. The HDD controller is same as in this board: https://bigbookofamigahardware.com/bboah/product.aspx?id=523

It is IDE, not SCSI. You can connect IDE HDD or CF-IDE directly.

[rmueller83]

Thanks for the clarification. Could you post a file name or CRC32 of the ROM file you are using? There seem to be several versions.

[OlegMishin]

No problem. I uploaded it into "ROM" folder.

[rmueller83]

Thank you, it has the same CRC as the one which is linked on https://amiga.resource.cx/exp/alfapower

[rmueller83]

@OlegMishin could you please add a flashable svf file like in the v1 project in the output_files directory?

[OlegMishin]

Hi @rmueller83, Done.

BR Oleg

[rmueller83]

Wow, that was fast. Thank you! 👍

[OlegMishin]

No problem. I was at my PC that time :)

Hello! I wanted to ask if the ROM programming is all done from an original Amiga with the “Octapussy” BIN or is it necessary to do some extra programming?

[OlegMishin]

Hi, The Flash can be programmed on a real Amiga with "flashem" tool included in "Software" folder.

How to program it with SVF file ? (RaspberryPI hardware)

[OlegMishin]

I have never used Raspberry Pi for CPLD programming. For Microchip I use OpenOCD e.g. as below command: "E:\openocd-v0.11.0\bin\openocd.exe" -f "E:\openocd-v0.11.0\scripts\interface\altera-usb-blaster.cfg" -c init -c "svf A500_8mb_ide.svf" -c "sleep 200" -c shutdown For Altera CPLD I use Quartus programmer. Both via ByteBlaster.

[FLT-1]

Hello. I built the project, with the main IC: “39SF020A” ; “KM416C4100BS-6”; “EPM7128STC100-10N” and I'm getting the Amiga screen red. What could be wrong? Do you have any idea ?

[OlegMishin]

Hi @FLT-1, I guess you already programmed the CPLD and FLASH. If so, check soldering.

[FLT-1]

I apologize in advance for the inconvenience... I've already checked all the soldering and contacts... I realized that the flash can be programmed via the Amiga, and to be able to guide myself, I question the CLPD, will it have to be programmed off the board or via JTAG?

[OlegMishin]

I beleve it is obvious, via JTAG. For Altera CPLD a standalone Quartus Programmer tool can be used with cheap USB blaster. No need to install complete Quartus.

I have never used Raspberry Pi for CPLD programming. For Microchip I use OpenOCD e.g. as below command: "E:\openocd-v0.11.0\bin\openocd.exe" -f "E:\openocd-v0.11.0\scripts\interface\altera-usb-blaster.cfg" -c init -c "svf A500_8mb_ide.svf" -c "sleep 200" -c shutdown For Altera CPLD I use Quartus programmer. Both via ByteBlaster.

hmm, why is that error?

"C:\OpenOCD\bin\openocd.exe" -f "C:\OpenOCD\share\openocd\scripts\interface\altera-usb-blaster.cfg" -c init -c "svf A500_8mb_ide.svf" -c "sleep 200" -c shutdown

[OlegMishin]

I assume, the USBblaster is functional and tested with other SW(e.g. Quartus Programmer). Maybe USB driver is not correct. Try Zadig to play with drivers: https://zadig.akeo.ie/

Did you try other USB drivers? I don't remember, which one was working for me.

[CCKMik]

Did you try other USB drivers? I don't remember, which one was working for me. yes, nothing works :(

USBblaster gives 3.3v, but we need 5v, Should I provide 5v from an external source?

You can do it two ways... either you put it on the Amiga board, turn on the power, the board (AMIGA) injects the voltages or you inject the power directly onto the board (Expansion) Pin 14 or 49 for +5v and pin 16 or 53 to GND. I've done it both ways and it worked. (I made two for my two A500s and they are working great)

[OlegMishin]

@FLT-1 , thanks for your comment. That is absolutely right. @CCKMik, I use another way. My USBblaster is upgraded with a switch to provide 5V from USB to target.

Did you use USBblaster for programming? could you show this photo of the correct connection ?

[OlegMishin]

Hi @CCKMik, Yes I do use USBblaster. The connection is quite straight forward. Please refer to the discussion in the previous version of the project: https://github.com/OlegMishin/A500_8MB_ide/issues/3 The only difference is in the JTAG connector footprint. Before it was through hole, now it is SMD.

[CCKMik]

Please refer to the discussion in the previous version of the project: [OlegMishin/A500_8MB_ide#3]

conclude from it:

" TLDR for this thread: don't waste your time with an USB Blaster clone or a Raspberry Pi. Get a FT232H board."

[CCKMik]

Hi @FLT-1, I guess you already programmed the CPLD and FLASH. If so, check soldering.

what is the required minimum soldering of parts to be able to program the altera chip ?

[OlegMishin]

I would recommend to solder JTAG pull-ups and decoupling capacitors for the CPLD. Please refer to this thread for same discussion: https://github.com/OlegMishin/A500_8MB_ide/issues/3
