66AK2H12: Srio Socket failed to bind in 66AK2H12

Part Number: 66AK2H12
Other Parts Discussed in Thread: TMS320C6678,

Hi,

In our custom board, 66AK2H12 (keystone2) processor is connected to TMS320C6678 (keystone1) processor thro SRIO switch ( one x4) and it is operating at 156.25MHz reference clock and lane speed is 5Gbps. We are running SRIO example project (tput_benchmark) in both processors. We modified benchmark.h for  processors' communication(Disabled loop-back ,Enabled Board to board, enabled over srio switch,) Keystone2 is configured as consumer. Keystone1 is configured as Producer. Producer side socket is created and binded successfully and it tries to send packet whereas in consumer (K2 side) socket  bind gets failed. Please find the log message of consumer side (K2 processor).

[C66xx_0]  CPU Frequency : 983040000 Hz
 PLL base frequency: 122880000 Hz
 PLL multiplier : 16
 PLL divider1 : 2
 PLL divider2 : 1

    Hi,

    Have you checked the documentation in packages/ti/drv/srio//test/tput_benchmarking/docs/

    See how you should configure the example in Section 9.3 Setting up C-S-C connection mode (core to core, with a SRIO switch).
    Have you modified benchmarking.h, as follows:
    Change the “IS_OVER_EXTERNAL_SRIO_SWITCH” define from “FALSE to “TRUE”, this will automatically set loopback mode to off and have the output show that the test was run using an external SRIO switch.

    Best Regards,
    Yordan

    Hi,

    Thanks for reply. I have gone thro the document. Yes i have already enabled IS_OVER_EXTERNAL_SRIO_SWITCH as true. Also loop back macro in benchmark.h is set as false.

    These points, i already mentioned in previous post. 

    Regards,
