Unable to receive data in Uart

Hello everyone i try to receive the data from the uartt but i cannot receive the data from the uart but i am able to write the data in the uart can someone please help me to receive the data from the uart
Program:

void receive_uart_response(void)

{

uint8_t rx_buffer[UART_BUFFER_SIZE] = {0};

fsp_err_t err = FSP_SUCCESS;

SEGGER_RTT_WriteString(0, "Waiting for UART response (2 seconds timeout)...\n");

TickType_t start_time = xTaskGetTickCount();

TickType_t timeout_ticks = pdMS_TO_TICKS(2000); // 2 seconds timeout

while ((xTaskGetTickCount() - start_time) < timeout_ticks)

{

err = g_uart0.p_api->read(&g_uart0_ctrl, rx_buffer, sizeof(rx_buffer));

if (err == FSP_SUCCESS)

{

SEGGER_RTT_WriteString(0, "Received Data: ");

SEGGER_RTT_Write(0, rx_buffer, sizeof(rx_buffer));

SEGGER_RTT_WriteString(0, "\n");

// Clear the buffer for the next read

memset(rx_buffer, 0, sizeof(rx_buffer));

}

else if (err != FSP_ERR_INSUFFICIENT_DATA)

{

SEGGER_RTT_printf(0, "UART read error: %d\n", err);

return;

}

vTaskDelay(pdMS_TO_TICKS(10)); // Small delay to prevent tight loop

}

SEGGER_RTT_WriteString(0, "UART receive operation completed.\n");

}
