TDA2EX17EVM: McSPI2 SCLK No Signal

Part Number: TDA2EX17EVM

Hi Sirs,

Config SPI2 Code as Below

#define MCSPI_OUT_FREQ (100000U) // (1000000U)
#define MCSPI_IN_CLK (48000000U)

void SPI2_To_MCU_Init()
{
uint32_t gChNum = 1 ;
uint32_t status = 1U; // FALSE


// open spi2 module power
*((volatile UInt32 *) (0x4a009700 + 0xf8)) = 0x02;
  while ((*((volatile UInt32 *) (0x4a009700 + 0xf8))) != 0x02) ;


// pin setting
HW_WR_REG32(SOC_CORE_PAD_IO_REGISTERS_BASE+CTRL_CORE_PAD_SPI2_SCLK,0x000C0000);
HW_WR_REG32(SOC_CORE_PAD_IO_REGISTERS_BASE+CTRL_CORE_PAD_SPI2_D1,0x000C0000);
HW_WR_REG32(SOC_CORE_PAD_IO_REGISTERS_BASE+CTRL_CORE_PAD_SPI2_D0,0x000C0000);
HW_WR_REG32(SOC_CORE_PAD_IO_REGISTERS_BASE+CTRL_CORE_PAD_SPI2_CS0,0x00060000);

// Perform a software reset.
McSPIReset(MCSPI2_BASE_ADDRESS) ;


//Configure static settings (such as SPI master) as required.
McSPIMasterModeEnable(MCSPI2_BASE_ADDRESS);
McSPICSEnable(MCSPI2_BASE_ADDRESS);


// Write MCSPI_SYSCONFIG
MCSPISysConfigSetup(MCSPI2_BASE_ADDRESS, MCSPI_CLOCKS_OCP_ON_FUNC_ON,
					   MCSPI_SIDLEMODE_NO, MCSPI_WAKEUP_DISABLE,
					   MCSPI_AUTOIDLE_OFF);

//Set transmit mode for the channel.
status = McSPIMasterModeConfig(MCSPI2_BASE_ADDRESS, MCSPI_SINGLE_CH,
                                   MCSPI_TX_RX_MODE,
                                   MCSPI_DATA_LINE_COMM_MODE_6, // D0: MOSI, D1:MISO
                                   gChNum);
if (0 == status)
   {
	   //config err
	   Vps_printf("\nTony:SPI2 config fail\n");
	 //  while(1); // looping
   }


//Configure SPI clock polarity/phase, clock divider,word length, and others for the channel.
McSPIClkConfig(MCSPI2_BASE_ADDRESS, MCSPI_IN_CLK, MCSPI_OUT_FREQ, gChNum, MCSPI_CLK_MODE_1);
McSPIWordLengthSet(MCSPI2_BASE_ADDRESS, MCSPI_WORD_LENGTH(8), gChNum);
McSPICSPolarityConfig(MCSPI2_BASE_ADDRESS,
                          (MCSPI_CH0CONF_EPOL_ACTIVELOW <<
                           MCSPI_CH0CONF_EPOL_SHIFT), gChNum);

// Reset the status bits.
McSPIIntStatusClear(MCSPI2_BASE_ADDRESS, 0) ;
	
}

and I rty to transmit one byte data like this

//Start the channel.
McSPIChannelEnable(MCSPI2_BASE_ADDRESS, gChNum);
McSPITransmitData(MCSPI2_BASE_ADDRESS, (uint8_t) (*p_tx), gChNum);
McSPIChannelDisable(MCSPI2_BASE_ADDRESS, gChNum);

but there is no signal on the spi2_sclk

are there any configs setting wrong or lose

by the way, the HW signal line is at RU17- 1A (C_SPI2_SCLK) on TDA2Ex EVM

Best Regards,Tony
