CC3220SF SPI同时数据传输时出现问题

SDK版本是多少，例程是否修改过

修改过，原SDK是还需要额外的两根线，我在这里直接去掉这两根线：主机代码：
SPI_Params_init(&spiParams);
spiParams.frameFormat = SPI_POL0_PHA1;
spiParams.mode = SPI_MASTER;
spiParams.transferMode = SPI_MODE_BLOCKING;
spiParams.dataSize = 8;
spiParams.bitRate = 2000000;
masterSpi = SPI_open(CONFIG_SPI_MASTER, &spiParams);
i = 1024；//发送1m数据
memset(masterTxBuffer, 0x55, 1024);
memset(masterRxBuffer, 0x55, 1024);
transaction.count = SPI_MSG_LENGTH;
transaction.txBuf = (void *) masterTxBuffer;
transaction.rxBuf = (void *) masterRxBuffer;
while(i)
{
transferOK = SPI_transfer(masterSpi, &transaction);
i--；
}
从机代码：
SPI_Params_init(&Spi_Params);
Spi_Params.transferMode = SPI_MODE_CALLBACK;
Spi_Params.transferCallbackFxn = transferCompleteFxn;
Spi_Params.mode = SPI_SLAVE;
Spi_Params.dataSize = 8;
Spi_Params.frameFormat = SPI_POL0_PHA1;

Spi_handle = SPI_open(CONFIG_SPI_0,&Spi_Params);
memset(g_ucTxBuff_a, 0x65, 1024);
Spi_transaction_a.count = RESIZE;
Spi_transaction_a.txBuf = (void *)g_ucTxBuff_a;
Spi_transaction_a.rxBuf = (void *)g_ucRxBuff_a;
while(1)
{

Spi_transferOK = SPI_transfer(Spi_handle, &Spi_transaction_a);
if(Spi_transferOK)
{

while(Spi_transaction_a.status != SPI_TRANSFER_COMPLETED);
}
}

改成了三线，用原例程正常吗？

你好，我已经这么做了。很可惜，还是出现一样的错误。如果可以，请您修改一下你的测试代码，工作在4线模式，主机设置的spiParams.bitRate = 15000000;（15MHZ），并且需要一次发送1M数据，从机设置为在接收数据时向主机发送数据，并在每次接收成功包后计数，等这1M的数据（主机发送完后）打印出来。如果可以请使用逻辑分析仪看下数据。

我的代码如下，使用examples\rtos\CC3220SF_LAUNCHXL\drivers\spimaster spislave。修改其中的slaveThread masterThread函数如下：

#define SPI_MSG_LENGTH 1024

void *masterThread(void *arg0)
{
SPI_Handle masterSpi;
SPI_Params spiParams;
SPI_Transaction transaction;
uint32_t i;
bool transferOK;
int32_t status;
status = sem_init(&masterSem, 0, 0);
if (status != 0) {
Display_printf(display, 0, 0, "Error creating masterSem\n");

while(1);
}
SPI_Params_init(&spiParams);
spiParams.frameFormat = SPI_POL0_PHA0;
spiParams.mode = SPI_MASTER;
spiParams.transferMode = SPI_MODE_BLOCKING;
spiParams.transferTimeout = SPI_WAIT_FOREVER;
spiParams.dataSize = 8;
spiParams.bitRate = 15000000;
masterSpi = SPI_open(CONFIG_SPI_MASTER, &spiParams);
if (masterSpi == NULL) {
Display_printf(display, 0, 0, "Error initializing master SPI\n");
while (1);
}
else {
Display_printf(display, 0, 0, "Master SPI initialized\n");
}
memset(masterTxBuffer, 0x55, SPI_MSG_LENGTH);
memset(masterRxBuffer, 0x55, SPI_MSG_LENGTH);
for(i = 1024;i>0;i--)
{
transferOK = SPI_transfer(masterSpi, &transaction);
/*等待其传输完成*/
if(transferOK)
{
while(transaction.status != SPI_TRANSFER_COMPLETED );
}
else
{
Display_printf(display, 0, 0, "spi transfail\n\r ");
}
}
Display_printf(display, 0, 0, "transfer done\n\r");
while(1);
}

从机的代码如下：
从机需要配置使用SW2注册为中断函数，当按下SW2就打印出计数的包：
void pushButtonInterruptHandler_SW3(uint_least8_t index)
{
Display_printf(display, 0, 0, "包的个数 %d\n\r",asd);
asd = 0;
}
void slaveThread(void)
{
SPI_Handle slaveSpi;
SPI_Params spiParams;
SPI_Transaction transaction;
uint32_t i;
bool transferOK;
freeze = 0xff;
asd = 0;
SPI_Params_init(&spiParams);
spiParams.frameFormat = SPI_POL0_PHA0;
spiParams.mode = SPI_SLAVE;
spiParams.transferCallbackFxn = transferCompleteFxn;
spiParams.transferMode = SPI_MODE_CALLBACK;
slaveSpi = SPI_open(CONFIG_SPI_SLAVE, &spiParams);
if (slaveSpi == NULL) {
Display_printf(display, 0, 0, "Error initializing slave SPI\n");
while (1);
}
else {
Display_printf(display, 0, 0, "Slave SPI initialized\n");
}
GPIO_setCallback(CONFIG_GPIO_sw2, pushButtonInterruptHandler_SW3);
GPIO_enableInt(CONFIG_GPIO_sw2);
memset(masterTxBuffer, 0x55, SPI_MSG_LENGTH);
memset(masterRxBuffer, 0x55, SPI_MSG_LENGTH);
while(1)
{
memset((void *) masterRxBuffer, 0, SPI_MSG_LENGTH);
transaction.count = SPI_MSG_LENGTH;
transaction.txBuf = (void *) masterTxBuffer;
transaction.rxBuf = (void *) masterRxBuffer;
transferOK = SPI_transfer(slaveSpi, &transaction);
if (transferOK) {
while(transaction.status != SPI_TRANSFER_COMPLETED);
asd++;
}

}
