MW 10:46 AM Software Development: RE: uPP support

Hi Brian,
For the OMAP-L138, pin-muxing is just a fact of life. If you would like to use ethernet and uPP, then it might make sense to use the MII interface instead of the RMII interface. Otherwise, there are RMII pins that do confl... Michael Williamson

BR 09:32 AM Software Development: RE: uPP support

Hi Mike
This sounds good. An additional question would be about the pin configuration for the uPP port. In the excel sheet for port pins between FPGA og uC I have noticed that some pins are shared between the uPP and the RMII ports. A... Brian Rasmussen

Hi Mike
Thanks for your quick reply. I will try it out.

MW 07:53 AM Software Development: RE: Can't extract release 2011-03

Hi Brian,
The .run file is really just a shell script. Turns out that it is calling out "/bin/sh" to run the script which self extracts, however it appears that it may require "/bin/bash" to operate correctly. I suspect that you may... Michael Williamson

BR 03:07 AM Software Development: Can't extract release 2011-03

Hi
I'm not able to extract the latest board support package release.
I have downloaded the "release_2011-03-31.run" file, it decompress as expected with no errors and then shows the user licence. If I then use the space key to get ... Brian Rasmussen

MW 10:53 AM Software Development: RE: uPP support

Brian,
You should not have a problem achieving the rates you mentioned above. We have accomplished similar throughput with other designs doing a similar data shuffle, but had the DSP processing data before sending it to the ARM.
T... Michael Williamson

BR 10:44 AM Software Development: RE: uPP support

Hi Mike
We have discussed about the uPP port, and we have decided to try and use it in our project, due to the nice 1Gbit/s DMA transfer to the DSP. This will make our system more complex, because we use the ARM core, the DSP and the ... Brian Rasmussen

BR 09:52 AM Software Development: RE: uPP support

Hi Mike
You can send me the code by email.
I have downloaded the latest BSP, but haven't had the time to look at it yet.
Best regards

MW 10:04 AM Software Development: RE: uPP support

Hi Brian,
Unfortunately, there is no linux side UPP driver available from TI. We have written one (it's rough) and are using it for the DSP core under DSP/BIOS for a couple of projects. The code for that is available in the more rec... Michael Williamson

BR 09:56 AM Software Development: uPP support

Hi
In the datasheet for the MityDSP L138 board there is a schematic with "uPP" interface between the OMAP and the FPGA. Is there a uPP Linux driver available, or an example project using uPP to communicate with the FPGA from a Linux a... Brian Rasmussen

MW 06:55 PM Software Development: RE: FPGA_GPIO input polling

Hi Brian,
Sorry for the delay. We are working on this, but it is a little more involved. I expect to have something to try in another week or so.
