11:46 AM ARM9 Based Platforms Software Development: RE: uPP receiving problem
I'm not a VHDL guy, so I can't say whether this will work as you have it. It sounds like you and your VHDL guy shoul... David Rice
11:09 AM ARM9 Based Platforms Software Development: RE: uPP receiving problem
Each time you call receive, a DMA is set up to fill the buffer you pass. Once that DMA completes, no data will be tr... David Rice
10:05 AM ARM9 Based Platforms Software Development: RE: uPP receiving problem
I don't see any reason that it wouldn't work, but I have seen issues with some interrupt levels not working. I stron... David Rice
09:49 AM ARM9 Based Platforms Software Development: RE: uPP receiving problem
A couple of things that I see are different from some code that I have working here:
I use nHWInterruptLevel = 7. ...

08:29 AM ARM9 Based Platforms Software Development: RE: uPP delay between transmissions
My first thought on seeing this is that it is probably a cache issue. After you set the values in the buffer, the va... David Rice

11:46 AM ARM9 Based Platforms Software Development: RE: DSP- EDMA Transmission problem
I'm not sure why you are dividing by 4 for the number of words to transfer (numwords>>2), but I think that is your pr... David Rice

08:46 AM ARM9 Based Platforms Software Development: RE: Can't get DMA using low level driver working on DSP
If you have cache enabled for the DDR, I don't think it should be much faster to use IRAM. Your DMA in this case wil... David Rice
