6670 BCP config QMSS CPPI

kaiyang liu

Hello, when I use BCP on 6670 in a example project, I get a descripto pCppiDesc. What's the purpose of following code: pCppiDesc = (Cppi_Desc *) (QMSS_DESC_PTR (pCppiDesc));? Thank you.

        if ((pCppiDesc = (Cppi_Desc*) Qmss_queuePop (hTxFDQ)) == NULL)
        {
      goto cleanup_and_return;
        }
        pCppiDesc = (Cppi_Desc *) (QMSS_DESC_PTR (pCppiDesc));
        Cppi_getData (Cppi_DescType_HOST, pCppiDesc, &pDataBuffer, &dataBufferLen);

Hi kaiyang,

Thanks for your post.

To know more on API references, there is a docs folder under pdk_C6670_1_1_2_6 of MCSDK 2.0 in which, you will find a html doc. on api_ref.html from the below location:

~\ti\mcsdk_2_01_02_06\pdk_C6670_1_1_2_6\packages\ti\drv\cppi\docs\api_ref

To know the function description of "Cppi_getData",

file:///C:/ti/Keystone_MCSDK/pdk_C6670_1_1_2_6/packages/ti/drv/cppi/docs/doxygen/html/group___c_p_p_i___l_l_d___f_u_n_c_t_i_o_n.html#gaedae71f47a89e85825ee6f8b6898e4c1

To know about Cppi_Desc Union Reference

~\ti\Keystone_MCSDK\pdk_C6670_1_1_2_6\packages\ti\drv\cppi\docs\doxygen\html\union_cppi___desc.html

Likewise, you could refer all modules, datastructures, files on CPPI low level driver documentation from api_ref html doc.

Thanks & regards,

Sivaraj K
