Prop2 FPGA files!!! - Updated 2 June 2018 - Final Version 32i

cgracey · 2015-09-26 11:51

UPDATED 2 June 2018 - Final Version 32i

This is the 2nd v32i posted. It has a new Prop123-A7 file that hopefully fixes whatever was wrong with the first-posted one.

WHAT's NEW:

* ROM now includes SD booter and TAQOZ Forth
* Silicon speed will be rated at 180MHz

This Verilog has gone to OnSemi and is the tentative final version, unless a bug is discovered.

Please give these latest files a sanity check with your FPGA boards.

Older news:

* BUG FIX from v32a - SETQ+WRLONG was writing incorrect 2nd long if prior SETQ2+RDLONG/WRLONG
* BUG FIX from v32a - SETQ2+WRLONG was writing incorrect 2nd long if prior SETQ+RDLONG/WRLONG
* Debug system greatly improved with common-sense breakpoint behavior, individual cog enables, 8-long ROM in cogs to facilitate entry/exit, more breakpoint conditions and status data.

If it looks like this:

Chip
P2 loaded into Prop123-A7 Ok.
16 cog leds program blinks ok.
No DAC output from sin_cos_dacs.spin?

What are your dac clock pin assignments?

David Betz · 2015-09-26 12:33

That's the one I have. I think there is a newer version with mounting holes on either side of the header. I just powered up my DE2-115 board and it is still running the most recent P2-hot image so I guess everything is working. I get a monitor prompt. I'm now downloading Quartus so I can program the new FPGA image. Thanks!!

Baggers · 2015-09-26 12:34

Thanks Chip, I'll have a play now, and let you know how it goes.

I just poked my scope into the upper VGA pin receptacles. It's outputting on Dac0 Green and Blue.

Thanks. Without doc's, it's kind of an adventure game.

Baggers · 2015-09-26 12:37

All the more fun

cgracey · 2015-09-26 12:41

It's neat to think how in the blink program, every cog is running in hub-exec simultaneously. That egg beater is going to town. All this time, I've just been doing one-cog compiles for testing. I've never seen it all work together, until tonight.

ozpropdev · 2015-09-26 12:49

Ok, confirm dac0 green and dac0 blue working.
cooment in code tricked me

'Goertzel mode, output sin/cos on dacs 1/0

Scope was connected to Dac0 red and dac1 red
Schematic refers to dac0 and dac1, pcb overlay refers to dac0 to 5.

We are swapping those signals around on the A9 board so it makes sense. Sorry about that. You might have heard about Mixed-up Signal Processing.

Peter Jakacki · 2015-09-26 13:03

Thanks Chip, I am dusting off my DE2-115 and the add-on and see how it goes

David Betz · 2015-09-26 13:32

I hate to admit it but I seem to have lost the instructions for programming an image into the DE2-115 board. I have the programmer downloaded but I'm not sure how to configure it to program Chip's image. Can anyone give me instructions?

ozpropdev · 2015-09-26 13:38

David
On DE2-115 set switch on left side to program

In Quartus programmer
Mode - Active serial programming
Open file DE2_115_prop2.pof
Check pconfigure
Press start

P.S.: USB cable connected to USB Blaster port top left corner of DE2-115.

Thanks! I made the mistake of trying to use JTAG mode and "Find Device". That doesn't work. :-)

Ugh. Now I can't use PNut.exe to load a program because my PropPlug got assigned COM24.

Never mind. I went into the device manager and reassigned it to COM2 and I now have 9 LEDs blinking! I assume that means that there are 9 COGs implemented on the DE2-115?

VonSzarvas · 2015-09-26 13:53

Could you go into windows device manager, show hidden items, then delete one of the com ports thats not being used, but allocated to one of the lower port numbers?

I just noticed that before I read your message. Very nice! Now, does anyone have a serial driver that will work with this image?

Rayman · 2015-09-26 14:31

Guess it's time to unbox my Parallax DE2-115 board... Got it that April 1 when P2 was too hot and wasn't a joke... Been sitting in unopened box since...

Thanks for the screen shots, answers a question about what we get with DE2-115...
Looks like 9 of 16 cogs (as mentioned) and 256 of 512 kB.

mindrobots · 2015-09-26 14:41

Hey! It's Saturday morning, here in the States, don't any of you guys have chores to do? Errands to run? Honey-do's to do? Kids to tote to soccer? Wives to appease?

...at least I can dream of P2 a bit more while I chore my way around the house.

You're right! Time to head to the dump...

Kerry S · 2015-09-26 15:02

Great job Chip!

Rayman · 2015-09-26 15:09

I think I almost understand the blinky example, but some things look magic...

What does "orgh 1" do? Why not just orgh ? Does this code start at $1000 (I think so)?

The last two lines with org and res x are hurting my brain...
Does the compiler load anything after "org" into cog before starting?
Or does this only work for "res" reserved space that doesn't need initializing?

Rayman · 2015-09-26 15:16

I think I see both Parallax DE2-115 add on boards and the FPGA123 board have a 40-pin header for access to P2 digital I/O.
Unfortunately, they are wired differently.

Looks like the DE2-115 board with give me P0..P28 with 3.3 V I/O on 40-pin header.
FPGA123 appears to give P0-P31 with 3.3 V I/O on 40-pin header.

Do I have this right?

Baggers · 2015-09-26 15:31

After getting DE2 out, visitors came, they've now gone and I've got it booted up and LEDs flashing!

Time to play!

Thanks Chip
