PROCESSOR-SDK-J721S2: j721s2 8.6 SDk version

Part Number: PROCESSOR-SDK-J721S2

Hi, 

We are using the J721s2 device in our application. In we are working on the R5F (MCU2_1). In this we are facing an issue with SDK 8.6. In sdk8.4 its working fine but sdk8.6 we are not able to send more than 3 16bits of data. in that we are using free RTOS.

    Hi,

    Can you please elaborate more on this? What interface are you using? Also, are you referring to any existing example in PDK or is it a custom example?

    Regards,

    Hi Partha,

    We are using the SPI interface. we are using the custom example in pdk. We are able to send only 3 16bit words .

    Hi,

    Can you please share the changes done in the existing example?
    Also, did you try the out of box demo? Are you facing issue with that as well?

    Regards,

    I used following initialization sequence.

    MCSPI_init();
    //SPI_socGetInitCfg(USS1_SPI_INST, &spi_cfg);
    SPI_socGetInitCfg(domain,USS1_SPI_INST, &spi_cfg);
    spi_cfg.baseAddr = (uint32_t)CSL_MCU_MCSPI0_CFG_BASE;
    spi_cfg.chNum = USS1_SPI_CH;
    spi_cfg.chnCfg[USS1_SPI_CH].tcs = MCSPI_CH0CONF_TCS0_ONECYCLEDLY;
    spi_cfg.chnCfg[USS1_SPI_CH].dataLineCommMode = MCSPI_DATA_LINE_COMM_MODE_6;
    // spi_cfg.chnCfg[USS1_SPI_CH].enableFIFO = 0u;
    spi_cfg.chnCfg[USS1_SPI_CH].trMode = MCSPI_TX_RX_MODE;
    spi_cfg.initDelay = MCSPI_INITDLY_0;
    spi_cfg.rxTrigLvl = 2; // MCSPI_RX_TX_FIFO_SIZE;
    spi_cfg.txTrigLvl = 2; // MCSPI_RX_TX_FIFO_SIZE;
    spi_cfg.edmaHandle = NULL;
    spi_cfg.dmaMode = FALSE;
    spi_cfg.enableIntr = FALSE;
    spi_cfg.chMode = MCSPI_MULTI_CH;
    //spi_cfg.chnCfg[USS1_SPI_CH].dmaInfo = NULL;
    SPI_socSetInitCfg(domain,USS1_SPI_INST, &spi_cfg);

    SPI_socGetInitCfg(domain,USS2_SPI_INST, &spi_cfg);
    spi_cfg.baseAddr = (uint32_t)CSL_MCU_MCSPI1_CFG_BASE;
    spi_cfg.chNum = USS2_SPI_CH;
    spi_cfg.chnCfg[USS2_SPI_CH].tcs = MCSPI_CH0CONF_TCS0_ONECYCLEDLY;
    spi_cfg.chnCfg[USS2_SPI_CH].dataLineCommMode = MCSPI_DATA_LINE_COMM_MODE_6;
    // spi_cfg.chnCfg[USS2_SPI_CH].enableFIFO = 0u;
    spi_cfg.chnCfg[USS2_SPI_CH].trMode = MCSPI_TX_RX_MODE;
    spi_cfg.initDelay = MCSPI_INITDLY_0;
    spi_cfg.rxTrigLvl = 2; // MCSPI_RX_TX_FIFO_SIZE;
    spi_cfg.txTrigLvl = 2; // MCSPI_RX_TX_FIFO_SIZE;
    spi_cfg.edmaHandle = NULL;
    spi_cfg.dmaMode = FALSE;
    spi_cfg.enableIntr = FALSE;
    spi_cfg.chMode = MCSPI_MULTI_CH;
    // spi_cfg.chnCfg[USS2_SPI_CH].dmaInfo = NULL;
    SPI_socSetInitCfg(domain,USS2_SPI_INST, &spi_cfg);

    MCSPI_Params_init(&spiParamsUSS1);
    spiParamsUSS1.mode = SPI_MASTER;
    spiParamsUSS1.bitRate = 250000;//16000000;
    spiParamsUSS1.transferMode = SPI_MODE_BLOCKING;
    spiParamsUSS1.transferCallbackFxn = NULL;
    spiParamsUSS1.transferTimeout = 0xFFFFFFFF;
    spiParamsUSS1.frameFormat = (SPI_FrameFormat)frameFormatEVS[1];
    spiParamsUSS1.dataSize = 16;

    MCSPI_Params_init(&spiParamsUSS2);
    spiParamsUSS2.mode = SPI_MASTER;
    spiParamsUSS2.bitRate = 250000;//16000000;
    spiParamsUSS2.transferMode = SPI_MODE_BLOCKING;
    spiParamsUSS2.transferCallbackFxn = NULL;
    spiParamsUSS2.transferTimeout = 0xFFFFFFFF;
    spiParamsUSS2.frameFormat = (SPI_FrameFormat)frameFormatEVS[1];
    spiParamsUSS2.dataSize = 16;

    i didn't referred any example but i was using the spi in 8.4 sdk same thing i am trying on the sdk 8.6.

    Hi,

    Let me review the changes done in SPI driver from 8.4 to 8.6 and get back.

    Hi,

    I reviewed the changes from 8.4 to 8.6 and I don't see any change that could cause this issue.
    Can you please take a dump of McSPI registers in 8.4 and 8.6, right before you initiate the transfer and compare to see if there are any differences?

    Parth
