Hi,
I can able to capture and process RF data properly from TI6670 for LTE_20MHz in CPRI mode.
Query: What are changes required to configure the AIF2 module in TI C6670 for LTE 5MHz in CPRI mode?
I cut pasted the below code which works for LTE_20MHz in CPRI mode.
------start of cut paste------------------------------
volatile TestObj testObjTab[TEST_NUM] = {
{//1st Test - CPRI 4x for LTE 20MHz
// link0 link1 link2 link3 link4 link5
{1, 0, 0, 1, 0, 0 }, // link enable
{4, 4, 4, 4, 4, 4 }, // link rate
{DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL }, // outboundDataType
{DATA_WIDTH_15, DATA_WIDTH_15, DATA_WIDTH_15, DATA_WIDTH_15, DATA_WIDTH_16, DATA_WIDTH_16}, // outboundDataWidth
{DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL, DATA_TYPE_DL }, // inboundDataType
{DATA_WIDTH_15, DATA_WIDTH_15, DATA_WIDTH_15, DATA_WIDTH_15, DATA_WIDTH_16, DATA_WIDTH_16}, // inboundDataWidth
{DIO_0, DIO_0, DIO_0, DIO_0, DIO_0, DIO_0}, // not applicable for LTE test
}
};
for (i=0;i<AIF_MAX_NUM_LINKS;i++)
{
aifObj.linkConfig[i].linkEnable = testObjTab[0].linkEnable[i];
aifObj.linkConfig[i].linkRate = (CSL_Aif2LinkRate)testObjTab[0].linkRate[i];
aifObj.linkConfig[i].sampleRate = AIF_SRATE_30P72MHZ;
aifObj.linkConfig[i].outboundDataType = testObjTab[0].outboundDataType[i];
aifObj.linkConfig[i].outboundDataWidth = testObjTab[0].outboundDataWidth[i];
aifObj.linkConfig[i].inboundDataType = testObjTab[0].inboundDataType[i];
aifObj.linkConfig[i].inboundDataWidth = testObjTab[0].inboundDataWidth[i];
aifObj.linkConfig[i].cpriPackMode = AIF2_LTE_CPRI_8b8;//AIF2_LTE_CPRI_1b1;//
aifObj.linkConfig[i].psMsgEnable = CPRI_FAST_CM;
aifObj.linkConfig[i].comType = AIF2_2_AIF2;
aifObj.linkConfig[i].dioEngine = testObjTab[0].dioEngine[i]; //NA for pkDMA
}
-----end of cut paste--------------------------------
I tried the following:
aifObj.linkConfig[i].sampleRate = AIF_SRATE_7P68MHZ;
aifObj.linkConfig[i].linkRate= 2; //as per AIF2 Programming user guide, Table-2
I haven't got the proper data. To me, not clear on what need to be set in "aifObj.linkConfig[i].cpriPackMode" for LTE_5MHz? Please help me. Or provide one example source code which configures AIF2 in 5MHz mode in CPRI mode.
Thanks in advance,
Srinivas V
