RTOS/XEVMK2LX: Bypass DFE for JESD204b, or use PCIe/SGMII IOs with custom made protocol?

Part Number: XEVMK2LX


Tool/software: TI-RTOS

Hi guys,

I already posted this question to the RTOS forum, but was not sure whether it better belonged here.

We would like to use the JESD 204b interface on our EVM to read data from an external FPGA. The data will be 8b/10b encoded with a custom made protocol, and we would like to bypass the DFE to read the data. Is that possible with RTOS?

If it is not possible, is there a way to use other IOs like SGMII or PCIe without using the protocol? We tried the GPIOs, but they are to slow for our purposes.

In general, after studying the examples that come with the latest processor SDK, I have the impression that they are all very complex. Is there like a minimal example for SGMII, PCIe and JESD204b available? Maybe I looked in the wrong places..

Cheers

Dorothea
