I2C gets stuck at EV8 I2C Event (I2C_EVENT_MASTER_BYTE_TRANSMITTING)

[AZama.693]

I am trying to get SMbus communication to work and it works fine most of the time but I have seen that after sometime it gets stuck at I2C event I2C_EVENT_MASTER_BYTE_TRANSMITTING.

I have implemented a timeout function which retries event 255 times but I can still see that the return I get from the I2C retry event is an error. I also tried to do MCU reset and re init I2C if it still gets stuck after timeout but then the mcu is resetting all the time.

Is my I2C_EventRetry function incorrect > Or is there any good way to handle this error?

Below is my Init, Transmit and Event Retry function.

void I2C_Init()
{
  /* Initialize I2C peripheral */
  I2C_Init(I2C1, I2C_SPEED, 0x00,
           I2C_Mode_SMBusHost, I2C_DutyCycle_2,
           I2C_Ack_Enable, I2C_AcknowledgedAddress_7bit);   // 0x00 is a dummy value. Only used in slave mode
					 
	I2C_Cmd(I2C1, ENABLE); // Enable peripheral
}
 
static void I2C_EventRetry(I2C_Event_TypeDef I2C_Event)
{
	uint8_t retryCounter = 0;
	do{
      Delay_Us(1); 
      retryCounter++;
	}while((!I2C_CheckEvent(I2C1, I2C_Event)) && (retryCounter < RETRY_LIMIT)); 
}
 
static void StartTransmit(uint8_t slaveAddress, uint8_t commandCode, uint8_t dataLength, uint8_t regAddress1, uint8_t regAddress2)
{
	/* Disable I2C acknowledgement */
	I2C_AcknowledgeConfig(I2C1, ENABLE);
	
  /* Send I2C START condition */
  I2C_GenerateSTART(I2C1, ENABLE);
 
  /* Test on I2C EV5 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_MODE_SELECT);
 
  /* Send slave address for write */
  I2C_Send7bitAddress(I2C1, slaveAddress, I2C_Direction_Transmitter);
 
  /* Test on I2C EV6 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED);
	
  /* Send the command code */
  I2C_SendData(I2C1, commandCode); 
 
  /* Test on I2C EV8 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_BYTE_TRANSMITTING);
 
	/* Send the Data length */
  I2C_SendData(I2C1, dataLength); 
 
  /* Test on I2C EV8 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_BYTE_TRANSMITTING);
	/* Send the Data byte */
  I2C_SendData(I2C1, regAddress1); 
 
  /* Test on I2C EV8 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_BYTE_TRANSMITTING);
	/* Send the Data byte */
  I2C_SendData(I2C1, regAddress2); 
 
  /* Test on I2C EV8 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_BYTE_TRANSMITTED); //EV8_2
/* Send Stop condition */
	I2C_GenerateSTOP(I2C1, ENABLE);
	Delay_Ms(1);
 
	 /* Send I2C START condition */
  I2C_GenerateSTART(I2C1, ENABLE);
 
  /* Test on I2C EV5 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_MODE_SELECT);
 
  /* Send slave address for write */
  I2C_Send7bitAddress(I2C1, slaveAddress, I2C_Direction_Transmitter);
 
  /* Test on I2C EV6 and clear it */
	I2C_EventRetry(I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED);
 
	/* Send the command code */
  I2C_SendData(I2C1, commandCode); 
 
  /* Test on I2C EV8 and clear it */
