OMAP-L138 eXperimenter Kit vs. OMAP-L138 eXperimenter Kit for Universities

Anyone ?

University kit has uPP port, right ? 

Bas,

A UI card is included with the Development kit and enables additional peripherals, including:

• LCD character display
• EMAC RMII interface
• Camera (image sensor)
• Push button switches
• UPP ADC/DAC
• Parallel NOR flash memory
• NAND flash memory
• Video Port Interface (composite, S-Video)

Pubesh,

Thanks.

Does Experimenter Kit provide expansion connector for uPP ?

I know of only one breakout board given on this website which is not currently available. Without expansion connector I can't interface anything to Experimenter Kit for University.

I need to transfer data from FPGA and A/D converter to Experimenter Kit via uPP, can you please help me out here ?

Thanks.

The OMAP-L138 offers a universal parallel port (uPP) and is the first TI device with an integrated Serial Advanced Technology Attachment (SATA) interface.

Pubesh,

I know everything which you mentioned.

I am asking for expansion connector for uPP. I am talking about J29 connector which has uPP signals, how can I interface FPGA with those pins without breakout board ?

Bas,

I'll do my best to support you here, but I am reaching the limits of my expertise with this.
I will check with the hardware expert on the same. We will get back you.

Pubesh,

Thanks a lot.

I am sampling at 10 MHz with 12 bits resolution, which means data rate is 120 Mbps. Transferring this kind of data rate to maintain real-.time is only possible via uPP. But I can't make physical connection between uPP and FPGA without expansion connector. 

I look forward for your input.

Thanks.

Hi BAS

I am not aware of anyone directly hooking up the uPP - FPGA using the LogicPD boards (experimenter/SOM etc). If there is some one who tried it in the community , hopefully they will pitch in on this thread.

I think the better and more tried and tested route , with proper hardware and firmware support for upp-FPGA would by the MityDSP board/SOM from Critical Link

Hope this helps

Mukul,

Problem with MityDSP board is that there is no direct interface to interface LVDS A/D converter for example, ADS5282EVM.

What are other possible ways to transfer data from FPGA to OMAPL138 with that high data rates ? Is it possible to do that using Ethernet or USB ? Are there sample code available ? Can they be done without using any OS ?

Thanks for your help.

I am afraid, not much help to your new set of questions

uPP and EMIFA are typically the commonly used interfaces to hook up to FPGA.

I have not seen Ethernet or USB based hook up to FPGA (won't you need similar IP on the FPGA?) , if you are looking for uPP like data rates both interfaces will fall short from that perspective too.

Driver code for what? If you are asking for driver code that natively interfaces with ADS5282 EVM over UPP or EMIFA, the answer is no.

The best reference again for firmware would be from CriticalLink for upp-FPGA.

No non-os software from TI apart from what you can find in Starterware.

The following page provides a good landscape on the software support for individual modules

Hi - 

Thanks, Mukul, for mentioning our product. 

As Mukul mentioned our MityDSP-L138F has uPP interfaced to a Xilinx FPGA on board our module. 

Our development kit, below, routes a number of FPGA I/O as LVDS pairs to headers on the bottom of the board. Is it possible that this may be of use to you in connecting to a data converter? We also have a data converter board that fits on these expansion connectors that's not yet published - perhaps that may help you as well.

Would you like more information on this? 

Thank you -
