Problem with using uart1 in PMF

Hi,all

I'm using the UART1 in PMF,which is based on idle profile.

I read the the  "user_app_config.h",and I have tried to add my own uart1 config at:

" struct soc_module modules[ ] ".

The uart1 config is referred from uart0 config ( uart_settings).

And the uart1 pin_mux config is also updated.

Here is my code:

/*
my own uart1 config,referred from "uart_settings"
*/

// specific settings for uart1 module (for power mgmt. framework)
// Add:2015-12-15
struct cc_uart_config uart1_settings = {
        PRCM_UARTA1,
        {
                UARTA1_BASE,
                80000000,
                19200,
                (UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE |
                 UART_CONFIG_PAR_NONE),
                16,
                NULL
        },
        {
                (UARTA1_BASE + UART_O_DR),
                UDMA_CH11_UARTA1_TX,
                (UARTA1_BASE + UART_O_DR),
                UDMA_CH10_UARTA1_RX
        },
        e_int_based,
        e_int_based,
        e_one_half,
        e_one_half,
        e_true,
        e_true,
        INT_UARTA1,
        NULL
};

        },

        {

                uart_driver_load            /* Driver LD */
        }

};

And nothing else was changed. 

Then I started  my system, it blocked at  " g_tUartHndl = uart_open(PRCM_UARTA0); ".

I don't know if I have missed any  other necessary configuration .
