Flashing the FPGA #5

Open Syntec1 opened 1 year ago

Syntec1 commented 1 year ago

Hi,

I understand this is a work in progress project, I would like to build 2 to test on a A2000 and A500. unfortunately I had a denied response for the other project. I am willing to share the info on the build, flash and testing from my end, and yes I'm experienced in building such boards. Maybe I missed it but I don't not see the code for flashing the FPGA, or is it yet to be created or still in development phase? If it is not possible to participate then at least I tried :)

Hi, this repository is only the hardware design, the PCB. Niklas Ekström has been successful at writing HDL for it and making it work in a 10M16SCU169C8G FPGA, you will have to ask him about firmware. The problem is the Intel Max 10 FPGAs have not been available and are still not available to source from anywhere since over two years now.

Hi guys,

Yeah over a year ago I was hacking on the HDL for ReAgnus and got a modified version of Minimig's Agnus implementation to run. Here is a picture of it running Silkwork: http://eab.abime.net/showpost.php?p=1544845&postcount=17

The problem I experienced with the ReAgnus design was that I felt it was mechanically unstable. And then as Jörgen mentioned, the Intel Max 10 has been virtually impossible to buy the last year. Both of those issues are addressed by a new design by Jörgen, ReAgnus-MegAChip, which is currently in a private repository since it hasn't been tested yet, but will hopefully be tested "soon".

I am not inclined to release the HDL I have written until we have a version of both hardware and HDL that I believe people can build and be happy with.

If you like then perhaps we can setup a Discord server where we can discuss ReAgnus development, and then maybe that will help move the development along at a faster pace?

You weren't "denied" anything @Syntec1

English is not my native language, Excuse me for expressing it incorrectly.

Hey there, are there any news on the firmware side or in establishing a Discord for Disussion? On Hardware side there could be several options including a removable low profile version without a socket (Using https://www.mouser.de/ProductDetail/575-3016015152127 after removal of the Agnus Socket) This way even a common PLCC Socket can be placed when needed.

Hi, I think frenchshark is looking into developing a firmware. I have no idea if it will be open source or not and how far he has come. Discussion in Retro Tinkering discord under Technical stuff -> modern-enhanced-or-replacement-parts.

He has a github page for it. https://github.com/fredrequin/AliceRE

Yeah, found that but unfortunately there's no firmware release yet.
