TMS320F28377D: How to connect to SFRA_GUI

Hi,

Recently I want to use SFRA to measure the transfer function of the loop.But first, I can't connect to SFRA_ GUI.The following are some programs of the serial port I configured：

// GPIO28 is the SCI Rx pin.
//
GPIO_setMasterCore(28, GPIO_CORE_CPU1);//
GPIO_setDirectionMode(GPIO_PIN_SCIA_RX, GPIO_DIR_MODE_IN);
GPIO_setPadConfig(GPIO_PIN_SCIA_RX, GPIO_PIN_TYPE_STD);
GPIO_setQualificationMode(GPIO_PIN_SCIA_RX, GPIO_QUAL_ASYNC);
//
// GPIO29 is the SCI Tx pin.
//
GPIO_setMasterCore(29, GPIO_CORE_CPU1);//
GPIO_setDirectionMode(GPIO_PIN_SCIA_TX, GPIO_DIR_MODE_OUT);
GPIO_setPadConfig(GPIO_PIN_SCIA_TX, GPIO_PIN_TYPE_STD);
GPIO_setQualificationMode(GPIO_PIN_SCIA_TX, GPIO_QUAL_ASYNC);

SCIA_Init(15000000, 57600);

void SCIA_Init(long SCI_VBUS_CLOCKRATE, long SCI_BAUDRATE)
{
// Note: Assumes Clocks to SCIA are turned on in InitSysCtrl()
// Note: Assumes GPIO pins for SCIA are configured to Primary function

int16_t j = 0;

SciaRegs.SCICCR.all =0x0007; // 1 stop bit, No loopback
// No parity,8 char bits,
// async mode, idle-line protocol
SciaRegs.SCICTL1.all =0x0003; // enable TX, RX, internal SCICLK,
// Disable RX ERR, SLEEP, TXWAKE
SciaRegs.SCICTL2.all =0x0003;
SciaRegs.SCICTL2.bit.TXINTENA =0;
SciaRegs.SCICTL2.bit.RXBKINTENA =0;
SciaRegs.SCIHBAUD =0x0000;

SciaRegs.SCILBAUD = (SCI_VBUS_CLOCKRATE/(8*SCI_BAUDRATE))-1;//0x0020; // 20h = 57.6Kbaud @ LSPCLK = 60/4 MHz

SciaRegs.SCICTL1.all =0x0023; // Relinquish SCI from Reset

//SciaRegs.SCIFFTX.all=0xE040; // ENable FIFO enhancement
SciaRegs.SCIFFTX.all=0x8040; // DISable FIFO enhancement
SciaRegs.SCIFFRX.all=0x204f;
SciaRegs.SCIFFCT.all=0x0;
SciaRegs.SCIPRI.bit.SOFT=0x0;
SciaRegs.SCIPRI.bit.FREE=0x1;

RcvTaskPointer = &GetCmdByte; // Initialize the CmdPacket Rcv Handler state machine ptr
RcvTskPtrShdw = 1; // DEBUG
SendTaskPtr = 0; // Init to 1st state
LowByteFlag = 1; // Start with LSB during Byte-to-Word packing

dataOut16 = 0;
dataOut32 = 0;

*memDataPtr16 = 0;
*memDataPtr32 = 0;

RcvTskPtrShdw = 0; // for debug

delayer = 0;

MemGetPtr = 0;
MemGetAddress = 0x00000000;
MemGetAmount = 0;

MemSetPtr = 0;
MemSetValue = 0x00000000;

// clear Command Packet
for (j=0; j<PktSize; j++)
{
CmdPacket[j] = 0x0;
}

j=0;

// init all dispatch Tasks
CmdDispatcher[0] = LifePulseTsk;
CmdDispatcher[1] = TextSet;
CmdDispatcher[2] = ButtonSet;
CmdDispatcher[3] = SliderSet;
CmdDispatcher[4] = VariableGet;
CmdDispatcher[5] = ArrayGet;
CmdDispatcher[6] = DataGet;
CmdDispatcher[7] = DataSet32;
CmdDispatcher[8] = SpareTsk08;

}

There is an option Boot on Connect on the interface for selecting serial ports. I don't know what this option means.

In addition, can you provide some SFRA examples for TMS320F28377S? I only found some examples of F28004x on the official website.

Thank you for reading my question.
