JN5168 UART only receive 5 bytes

I only can receive 5 bytes from UART0 with JN5168. Who can tell what the reason is? Thank you!

void UartInit(void)
{
   vAHI_UartSetRTSCTS(UART, FALSE);
   vAHI_UartEnable(UART);

   /* Reset UART */
   vAHI_UartReset(UART, TRUE, TRUE);
   vAHI_UartReset(UART, FALSE, FALSE);

   vAHI_UartSetBaudRate(UART, E_AHI_UART_RATE_115200);

   /* Set remaining settings */
   vAHI_UartSetControl(UART, FALSE, FALSE, E_AHI_UART_WORD_LEN_8, TRUE, FALSE);
   vAHI_UartSetInterrupt(UART, FALSE, FALSE, TRUE, TRUE, E_AHI_UART_FIFO_LEVEL_1);

    vInitPrintf((void *)vPutChar);
}

PRIVATE void vProcessIncomingHwEvent(AppQApiHwInd_s *psAHI_Ind)
{
   if (psAHI_Ind->u32DeviceId == E_AHI_DEVICE_UART0)
   {
       if ((psAHI_Ind->u32ItemBitmap & 0x000000FF) == E_AHI_UART_INT_RXDATA)
       {
           /* Store Data */
           uart0_rxBuffer[uart0_rd] = (uint8)((psAHI_Ind->u32ItemBitmap & 0x0000FF00) >> 8);
           uart0_rd = (uart0_rd + 1) % RX_BUFF_SIZE;
       }
   }
}

Hi Liang Guo,

You are enabling the interrupt. You could use the ISR.

PUBLIC void APP_isrUart(void)
{
    unsigned int irq = ((*((volatile uint32 *)(UART_START_ADR + 0x08))) >> 1) & 0x0007;
    uint8 u8Byte;

    if (irq & E_AHI_UART_INT_RXDATA) {
        uint8 u8Byte = u8AHI_UartReadData(UART);
        if(ZQ_bQueueSend(&APP_msgSerialRx, &u8Byte) == FALSE)
        {
            /* Failed to send the message to queue */
        }
    }

    if (irq & E_AHI_UART_INT_TX) {
        if(ZQ_bQueueReceive(&APP_msgSerialTx, &u8Byte) == TRUE)
        {
            vAHI_UartWriteData(UART, u8Byte);
            /* decrement activity counter for dequeued data */
        } else {
            /* disable tx interrupt as nothing to send */
            UART_vSetTxInterrupt(FALSE);
        }
    }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Mario:

Thank you for your reply！I use the ISR but it can't work, so I can only use the APP Queue API.

Hi Liang Guo,

Did you solver the uart callback?
