why can we ignore PKTIO IF Config for PA in mcsdk-video demo?

zhao sun

Hi,

I am a little confused with a section of code in function "siuVigdkInit":

... ...

        case MGB_MD_PKTIO_IF_CONFIG:
#ifndef PA_SS
            /*ignore PKTIO IF Config for PA*/
            siuPktioIfCfg(msg);
#endif
            break;

... ...

I want to know why can we ignore PKTIO IF Config for PA ? If so, Where

shall we configure the SGMII for the test board?

Thank you!

Hi Sunzhao,

The SGMII init code is in C:\Program Files\Texas Instruments\mcsdk_video_2_0_0_10\dsp\siu\c64x\shannon\siuhal.c: siu_pktio_mac_init(), which then calls Init_SGMII(). siuPktioIfCfg is not used.

Thanks,

Hongmei

Hi Hongmei,

It seems that there's only one call path in the project:

.. -> siuPktioIfCfg()-->siu_pktio_macport_config()-->siu_pktio_mac_init()->..

If siuPktioIfCfg() is not called, siu_pktio_mac_init() will not be called either.

Thanks a lot!

Sunzhao,

siuPktioIfCfg is called from host by sending the command (MGB_MD_PKTIO_IF_CONFIG)
