I'm use STM32F412RGT. IDE is IAR.

if(__HAL_I2S_GET_FLAG(&hi2s3, I2S_FLAG_FRE) && __HAL_I2S_GET_FLAG(&hi2s3, I2S_FLAG_CHSIDE))

 

{

 

__HAL_I2S_DISABLE(&hi2s3);

 

while(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_4) != GPIO_PIN_SET)//WS

 

{

 

asm('nop;');

 

}

 

uint32_t tmpreg = hi2s3.Instance->SR;

 

__HAL_I2S_ENABLE(&hi2s3);

 

}

After executing this code, I again get a Frame error flag (FRE)

#stm32f412rgt #i2s

I apologize for the worry, it was a hardware problem.
