UART and Thread

Hi,

Thanks for reply.I'm using FRDM-64f board.First I checked my code alone

using the project uart non blocking,with interrupt and which is working

perfect.Then I moved the same code into the lwip tcp echo demo

project,which is now showing some issues.

nRet = UART_DRV_Init(BOARD_DEBUG_UART3_INSTANCE, &uartState,

&uartConfig);

pFunc = (uart_rx_callback_t *)uart_Callback;

UART_DRV_InstallRxCallback(BOARD_DEBUG_UART3_INSTANCE

,(uart_rx_callback_t)pFunc ,&rxChar, 0, NULL);

NVIC_SetPriority(I2C0_IRQn, 3U);

while(true)

{

ReceiveCommandFromSerial();

UART_DRV_ReceiveData(BOARD_DEBUG_UART3_INSTANCE , &rxChar , 8u);

}

void uart_Callback()

{

__asm("nop");

}

If I use UART_DRV_SendData() function the whole board is getting hanging.

Regards
