TMS570LC4357: tms570lc4357 mibspi can receive

Hello,

I use tms570lc4357 mibspi5 to control flash (s25fl064l). The mibspi sends normally, but the data returned by flash cannot be received. The oscilloscope show that data has been sent and the flash has returned the data, but the software has not received the data.

Mibspi5 internal loopback test was successful;

mipspi5 input/output loopback test both successful;

some code: 

void mibspi_test_main(void)
{
/* USER CODE BEGIN (3) */
int i = 0;

sciDisplayText(sciREG3, "\r\nmibspi test ......\r\n", 22);
/* enable irq interrupt in */
_enable_IRQ_interrupt_();

/** Initialize MIBSPI */
mibspiInit();
mibspiGetrecvbuf(mibspiREG5);

//mibspiEnableLoopback(mibspiREG5, Analog_Lbk);
mibspiEnableGroupNotification(mibspiREG5, 0, 0);
while(1)
{
mibspiSetData_my(mibspiREG5, 0, &tx_data5[0]);
mibspiTransfer(mibspiREG5, 0);
sciDisplayText(sciREG3, "\r\nmibspi test2 ......\r\n", 23);

while (0 == mibspiIsTransferComplete(mibspiREG5, 0))
{
sciDisplayText(sciREG3, "\r\nspiwait.\r\n", 12);
}
sciDisplayText(sciREG3, "\r\nmibspi compl ......\r\n", 23);
mibspiGetrecvbuf(mibspiREG5);
mibspiGetData(mibspiREG5, 0, &rx_data5[0]);
//dbgPrintf(" mibspiGetData group=%d, data=%d:\r\n", 0, rx_data5[0]);
mibspiGetrecvbuf(mibspiREG5);

for (i = 0; i < 8; i++)
dbgPrintf(" mibspiGetData group=%d, %d, data=%d:\r\n", 0, i,rx_data5[i]);
}

}
