FPGA Replay Board

[freqmax]

Asfair, the reason for the delay is that the boards need to be checked and shipped. The motivation is not profit per se. I think the mailed requests shows quite clearly how large the interest is.

I knew it! the aliens has hidden an Amiga 500 inside my MiniMag that toggles the parallel port at 565 terahertz to generate photons

KryoFlux can be connected as an USB device but they don't specify what USB API it's using so software compability can't be determined. Also there's no documentation on what kind of USB devices FPGA Arcade has support for beyond a USB mouse.

Wait until we get 4 GB chip ram..

Fire up the ISE makefiles and bring the thick AGA specification

@Darrin, Conspiracy! *drums*

Does the USB handler in the FPGA Arcade handle USB Ethernet adapters good enough to present an API that assembler code on the 68k side can make use of to establish TCP/IP connections?

* So boards without the new bootloader works out of the box but without the  features of said option?
 * This new batch of ARM cpus only has slightly slower flashmemory write cycle? not slower flashmemory read accesstime?
 * Does the dead 1.2 V supply mean that you have to check and replace this on all boards?
 * How is the DDR memory self calibration going?

Whats VNC2?, If I recall it correctly, the ARM cpu is the USB-host and sends this to the FPGA via i/o. I like the everything-on-one-board-solution Perhaps an option would be to handle other USB devices by just forwarding the raw data and let the Amiga side deal with the configuration of endpoints etc.

What I would like is to be able to just plug the board via USB ethernet to the local network and run with it, without messing with any pc-2-sd-2-arcade-repeat. Firmware updates would be just a matter of pressing a key.

Daughterboard is nice for extras lik a CPU but for Ethernet I would prefer it to be on the main board ie KISS.

Seems I misstok the P13 micro USB conncector for the PS/2 connector in USB mode. But if the FPGA has the electrical control of the PS/2 port + adapter to USB. Extended device support is only .bit file away

AT91SAM7S256-AU-001
CPU: ARMv4T (ARM7TDMI)
Freq: 18.432 MHz (max 55 MHz)
RAM: 64 kB
ROM: 256 kB

VNC2
CPU: 16-bit Harvard
Freq: 12 MHz
RAM: 16 kB
ROM: 256 kB

I think I know which MCU chip that would be tasked to handle the USB hodepodge.

[freqmax]

I know it was a mere suggestion on which one that has the most CPU power.

Btw, how much code size and MIPS does it require to use a USB device like a Ethernet dongle? (estimate), perhaps this estimate at 300 kB of RAM is realistic? in addition to the on board 4 MB flash.

Anyway at present an external USB/Disc/Ethernet solution is the required path.

[freqmax]

Are these "features" incorporated into the core?
abime.net: Undocumented Amiga hardware stuff

[freqmax]

Well because the FPGA i/o goes straight to the PS/2 data+clock is available, one could use them as D+/D- and with the right core you can bang USB right there.

[freqmax]

Signal levels can be set with FPGA configuration, and if not one can fix that externally. Less electronics than another MCU.
Two 3,3V level signals that forms a differential signal together shouldn't be that hard to accomplish. Ofcourse it won't be 100% to specification but that hasn't hindered Amiga fans before

[freqmax]

PS3 controller outputs continous signal? ordinary Commodore joystick only generate Back - Forward etc.. plain binary.

[freqmax]

This is a great addition to FPGA Arcade Makes it more Amigaish !

Better start coding of the thermal fatigue emulation module..

What's a soak test?
