- 10:46 AM FPGA Development: RE: I/O voltage
- No problem, it can wait a while.
Sounds like the SOM may have been catered for. Any thoughts on the dev kit or do ... - 09:03 AM FPGA Development: RE: I/O voltage
- Hi Nigel,
The best guy to answer this question is on break this week and a good chunk of next week, can you wait f... - I would like to interface the MityARM-5C SX dev kit to an existing piece of equipment for evaluation purposes, howeve...

- 05:17 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
I'm still confused about this. Would it be possible to provide an example of multiple packets?
For exam...

- 06:36 PM FPGA Development: RE: HPS Memory Controller
- The descriptors are pushed onto a descriptor FIFO that the dispatcher reads from to start each transaction. So with s...
- 05:18 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
Is there any timing diagram with the SGDMA? I want to control some of the signals directly in the FPGA.
... - 04:49 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
I'm confused about this, does the Go signal go to "0" after each transfer such that I have to toggle it ba... - 04:28 PM FPGA Development: RE: HPS Memory Controller
- Yes, you need to set the go bit so the dispatcher knows that the descriptor is ready to be read.
Dan - 12:17 PM FPGA Development: RE: HPS Memory Controller
- Hi again,
Just reading through the document. Do I have to set GO to '1' each time I update the descriptor?
Than... - 12:12 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
I'm changing the write address in the descriptor in the VHDL. But it's still only writing to the first add...

- 03:53 PM FPGA Development: RE: HPS Memory Controller
- Hi Jack,
Park Writes – When set the dispatcher will continue to reissue the same descriptor to the write
master w... - 03:37 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
What's parked write? Is that just writing to one address only?
Is the descriptor like an address line?
... - 02:26 PM FPGA Development: RE: HPS Memory Controller
- Hi Jack,
Each packet needs its own descriptor, unless you are using parked writes. The descriptor is what tells th... - 02:15 PM FPGA Development: RE: HPS Memory Controller
- Hi,
Just a question with regarding sending these data as a package.
I know that the data in the package will be...

- 03:14 PM FPGA Development: RE: HSMC to GPIO
- Hi Jack,
The 5CSX dev board follows the Altera defined pinout for HSMC so that should work.
Dan - Hi,
Is HSMC on base board laid out the same pin out as this particular Terasic daughter board (this is what Altera...

- 06:14 PM FPGA Development: RE: HPS Memory Controller
- Beautiful Work! Thank you so much!
Jack - 05:57 PM FPGA Development: RE: HPS Memory Controller
- O of course! Can't believe something simple like that slipped my mind.
Thank you so much! Hope this works!
Jack - 05:51 PM FPGA Development: RE: HPS Memory Controller
- Hi Jack,
1) Hmm, I believe that error is from qsys generate not being run. Let me know if after running generate i... - 05:35 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
A couple of issues:
1. I am having trouble compiling the code. It's returning warnings and errors like ... - 03:34 PM FPGA Development: RE: HPS Memory Controller
- Jack,
I have created a new wiki section and have added the hps ddr example there. "LINK":http://redmine.criticalli...

- 08:23 PM FPGA Development: RE: HPS Memory Controller
- Hey Jack,
My plan is to get it up Thursday afternoon. I currently have the FPGA side done but need to finish up th... - 05:18 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
When would you be able to make the examples available?
Thanks!

- 04:28 PM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Dan,
We would like to use the HPS DDR as well, but as you can see from my numerous posts, we are really stuck o... - 04:17 PM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Jack,
Hmm, are you using the DDR SDRAM Controller with UniPHY in your QSYS project?
Also with this first rel... - 02:34 PM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Dan,
I don't see the TCL file that you are referring to. All the tcl files that I have are for HPS DDR not FPGA... - 02:30 PM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Jack,
Did you also run the IO Standard TCL file generated by the tools?
Dan - 02:25 PM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Dan,
I ran the tcl script that you attached on this thread.
But when I tried to compile, it gives me errors ... - 02:21 PM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Jack,
The IO Standard TCL file should be auto-generated by the tools.
To run it from Quartus:
1) Go to Tool... - 12:32 PM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Dan,
Could you provide the TCL file for the IO Standard as well please?
Thanks!
Jack - 10:52 AM FPGA Development: RE: FPG DDR3 Memory Pin Assignment
- Hi Jack,
I have attached a TCL file that will setup the pin assignments for the FPGA DDR.
Dan - 11:31 AM FPGA Development: RE: Link Down
- Hi Dan,
It happens while it's idling and booting up.
Thanks!
Jack - 11:05 AM FPGA Development: RE: Link Down
- Hi Jack,
Is this while the dev kit is just idling in linux? Or is this just during boot up?
Dan - 11:03 AM FPGA Development: RE: HPS Memory Controller
- Hi Jack,
Have you taken the SDRAM FPGA port out of reset? The register is called hps.sdr.ctrlgrp.fpgaportrst, the ...
