software OS4   software OS4 : Sam440ep_LatticeXP package available
   posted by m3x on 25-Mar-2012 12:25:16 (3232 reads)
Bassano del Grappa (Italy) - 24 March 2012

ACube Systems is happy to release a package to explore and enhance the capabilities of the LatticeXP FPGA available on the Sam440ep mini-itx and flex-atx boards.

With the manual, examples and tools of the package it's possible to implement new functionalities into the FPGA, to further strengthen your AmigaOS experience on your Sam440ep board.

The package contains:


- VHDL source code (released under GPL) of the firmware currently used on Sam440ep boards
- the original bitstream installed at the factory (to restore the original firmware)
- a porting of the VME12 utility which can reprogram, via the JTAG interface, the FPGA on the fly under AmigaOS 4.1 (*)

(*) a simple hardware modification and a cable are required

Download the Sam440ep_LatticeXP package here or from OS4Depot.

Nice Now we need to know what is feasible with SAM 440 FPGA

@vox,

Any VHDL or Verilog Program able to be compiled into an image loadable for a Lattice XP2 FPGA...

and that is quite a collection of things (even possibly a full 680x0 CPU option)

Thanks, ACube, for supporting all your hardware (and customers) -- from the oldest to the newest.

Thanks, but we need the sound drivers for the Sam 460 too.

This is really a big step in the right direction.
Now lets explore this thing.
Keep up the good work.

@Everyone
Screen grabs, and a few Youtube videos of this setup would be nice.

Grazie ACube!

If I only knew what we are talking about...... I gotta study harder.

Albeit it took quite a while that's cool news. An FPGA is IMHO way more intersting and versatile than a random µC. With 20k cells the capacity of the Lattice XP is big enough for quite some things.

20k cells? It's got 6k LUT4s, from what I can see (the code builds for LFXP6C).

6k isn't a lot, but yes, you can do some things. I'm guessing from the code that the FPGA has a 16 bit databus with 4 address pins and a chip-select going to the CPU and that it has a large IO connector you can connect to? At top level, there is PDATA (0 to 15), PADD (27 to 30) and something called LINK(0 to 79) which isn't even used.

GPIO including cool things like detecting and/or counting pulses that you couldn't poll for directly) immediately springs to mind. Amiga joystick is trivial, mice is easy and even keyboard shouldn't be too difficult if you have enough clock resources. At a stretch, Amiga floppy. Maybe CIA timers. Paula uses DMA for sound so that's out of the question. Clock port could be nice, maybe?

If I had a Sam, I would try to start with Amiga joystick (as this is simply GPIO) and mouse (quadrature decoder to give a simple count that a driver could read much like on the Amiga) support, and extend the number of registers. If you add an address register to go with the user register, you could have a small memory map that requires two cycles for a read or write. But for this you would need to block any other thread from accessing the FPGA until your two-cycle operation is completed.

http://www.allpinouts.org/index.php/Mouse/Joystick_Amiga_9_pin
http://www.fpga4fun.com/QuadratureDecoder.html
(so in essence, wire it up for a 9 pin joystick and add an X and Y counter register alongside the direct input state register). To avoid damage, some external circuitry is needed to handle ESD and over voltage. Nothing fancy, RS422 transmitters and receivers are very good at this. Wire one pin of a 3.3V supplied ESD protected differential receiver to ~2.5V, this turns it into a schmitt trigger. A 5V receiver can also be used, but needs a dampening resistor between it and the FPGA pin. For outputs, a 5V ESD protected differential driver can give you positive and negative versions directly from a single FPGA pin. And should normally work with a 3.3V FPGA driving it.

This weeks pet peeve:
Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean.

I would like to ask some information from the Sam440ep Flex FPGA physical connection.

I like use:

LINK : inout STD_LOGIC_VECTOR(79 downto 0);

But there is nothing information about her in the release pack, which can be assign pin?

I was able to find out those pin are connected to, which has its diamond shaped marked:
