Hi,

made this board from jbilander ...

Can PLEASE someone help me to build the firmware version to burn with GOWIN ???

I don't understand this programming parts ...

When I try to compile it in GOWIN editor I got errors ...

https://github.com/jbilander/SF2000-FW

THX

P.S.: If someone has the patience to explain me it could also be a solution ...

THX all

[jbilander]

Hi this should be straight-forward. Just right-click and run "Clean&Rerun all", don't forget to check that Dual-Purpose pins are set like this below too:

[Nbdy]

Still got error ...

All set in config like you set in second pic ...

[jbilander]

Ah, just right-click and disable the testbench.v file, it's not used...

[Nbdy]

OK, but what further, again some errors ...

Hi, it's because you have a space in the project directory path:

Managed to program ...

THX

DIdin't know that space will make souch trouble ...

THX again

Enjoy your card dude. Jbilander's projects are top quality

[Nbdy]

Ufffff.....

Have problems ....

Inserted the card, removed the CPU from amiga ....

BUt don't have a boot screen ....

Even the SW1 is on or off ...

WHat do I do wrong ....

Didn't come to flash a rom image to the SF2000 ....

When the Eprom with 2.00 is inserted I get a boot screen, but when I attach a drive intern or extern i don't have a boot from that drive (gotek) even no boot picture ....

I removed the eprom an put a diagrom, don't get the pic from diagrom, even the colors on the rom "boot" are different ...

Leaved the amiga without rom and CPU, but got only a black screen ...

THe card is inserted with the internal adapter, also from jbilander's git ...

The rom flashed to 39LF040 is the octacombined, also downoladed from SF2000 page link ...

WHat am I missing ????

Did I put, or didn't I put some jumper on the SF2000 ????

What jumpers should be on for the first "power on" ???

HELP ...

THX

[Nbdy]

Trying with all positions of jumper ...

But no success ...

Tryed with and without CPU, no boot screen ...

Without the card the amiga boots normaly ...

It's an rev.5 .... does this make the trouble ???

Hi, You need to do basic troubleshooting. Start by checking that the 7 MHz is generated correctly, U7, and start by removing the internal DIP 68k CPU and set the accelerator with JP5 to generate the E-CLK. Check with a logic analyser or oscilloscope that 7 MHz and E-CLK clock looks ok. Also verify that the adapter you're using has solid contact from the 86-pin expansion to all goldfingers on the accelerator. Also check voltage to level shifters is 4.3V and signals on the other 3.3V-side looks ok, Start there.

Managed to boot, both gotek work as df0: and df1: ....

But can't flash the rom image to SF2000 ...

I got an error :

expected to see manufacturer id 008F but got FFFF instead
Check that rom overlay is switched off and try again

The JP9 is off

Question :

Can I boot from SD card as hard drive ????

What purpose has the SD card slot ???

THX

[Nbdy]

It runs stable on 21MHz ... 28 some soft reboots ...

Also 8MB recognized as FAST ram ...

Kick 2.04 on the A500 board ...

Still didn't manage to flash the SF2000 ...

Any command I provide on sfflash it gives me the error above ...

ANd it will not recognize the SD card or the CF card as hard drive ...

Hi, with a genuine MC68SEC000AA20 you should be able to run it at 42 MHz. Definitely 28 MHz. Your mileage may vary dependent of what CPU you have in there. The SD-card functionality is not implemented yet!, contribution by the Amiga community is most welcomed. Driver and HDL (4-bit SDIO or even 1-bit SPI) needs to be developed. I tinker with other stuff at the moment. IDE works and you can boot from it provided you have programmed the 39LF040 ROM (with Oktagon/Oktapus.) and put it in U14 socket. Also requires that the 74LVC245 buffers are in place and working. Check in sysinfo that the Zorro PICs are shown and the Oktagon-driver are loaded. Check pics on github for how this is supposed to look.

Regarding LIV2:s excellent sfflash-tool, are you using a genuine SST39LF802C chip?. Also check RN5 pull-up resistors and soldering. For sfflash to work you need to boot on the Motherboard ROM which means JP9 open. I have only tried using it with KS 3.1 on motherboard (Rev 6A) and that worked like a charm even with different CPU speed settings.

Managed to flash with 3.2.2 kick ...

And also on an ver.6 A500 ...

The rev.5 will not boot with 3.2.2 ....

I have 2 Zorro devices shown as oktogon 8MB and 64kb like your first 2 on the picture ...

Is it possible to write a second ROM (see that there is bank0 and bank1) and how to select them ???

And one more, for the oktogon driver the JP8 should be closed ????

ANd verry strange, now with 3.2.2 rom in bank1, I got a lot of jellow screen on boot ... no mather how the clock is set ...
