Hi,

After adding printf we found I2C_WaitOnTXISFlagUntilTimeout flag is not being set...where could be the issue..kindly let us know

 while (hi2c->XferCount > 0U)

  {

   /* Wait until TXIS flag is set */

   if (I2C_WaitOnTXISFlagUntilTimeout(hi2c, Timeout, tickstart) != HAL_OK)

   {

    printf("inside while 1 HAL error = %d ",HAL_ERROR);

    return HAL_ERROR;

   }

regards

Ravi
