- 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...

- 12:23 PM FPGA Development: RE: HPS Memory Controller
- Hi Dan,
We figured it out last week. So we are fine with this for now.

- 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...
