LP-AM263: QSPI Flash read/write test in configuration mode

Hello Louis,

Can you share your example that you have tried for accessing QSPI flash in configuration mode? 

Regards,
Gunjan

Hi Gunjan,

We modified QSPI_norFlashRead and QSPI_readConfigMode in SDK 09.01 example(qspi_flash_diag_am263x-lp_r5fss0-0_freertos_ti-arm-clang).

int32_t QSPI_readConfigMode(QSPI_Handle handle, QSPI_Transaction *trans)
{
    int32_t status = SystemP_SUCCESS;

    if((handle != NULL) && (trans != NULL))
    {
        QSPI_ReadCmdParams reParams;
        QSPI_Object  *object = ((QSPI_Config *)handle)->object;

        reParams.cmd = object->readCmd;
        reParams.cmdAddr = trans->addrOffset;
        reParams.numAddrBytes = object->numAddrBytes;
        reParams.rxDataBuf = trans->buf;
        reParams.rxDataLen = trans->count;

        status = QSPI_readCmd(handle, &reParams);
    }
    else
    {
        status = SystemP_FAILURE;
    }
    return status;
}

int32_t QSPI_norFlashRead(QSPI_Handle handle, uint32_t offset, uint8_t *buf, uint32_t len)
{
    int32_t status = SystemP_FAILURE;

    QSPI_Transaction transaction;

    QSPI_transaction_init(&transaction);
    transaction.addrOffset = offset;
    transaction.buf = (void *)buf;
    transaction.count = len;
    status = QSPI_readConfigMode(handle, &transaction);

    return status;
}

Also, Do you have access QSPI flash example in configuration mode?

Please advise, thanks!

Hi Louis,

I am looking into it. Please expect a reply by tomorrow.
