Keystone 2 transmit 10G packet from DSP

Hello

We are trying to start transferring 10G packets on the DSP side using a custom k2h family board. I Attach a test non-working project. This project is based on the examples and source code of the SRIO driver, the initialization of serdes is taken from the sedes_diag examples. The code for configuring XGE was taken from the post at e2e.ti.com/.../391590. At this stage, an error occurred while getting the descriptor from the queue when trying to send packets greater than NUM_TX_DESC. Any help is appreciated. Thank.

    Hi,

    Could you share which Processor SDK RTOS version are you using? If you have a K2H evm, what I can recommend is follow this guide to setup linux xgbe:

    See the XGMII & RGMII related part of the above guide and check what are the correct register settings to enable Xgbe and SerDes for 10 G ethernet communication.

    Best Regards,
    Yordan
