FFTC_0和FFTC_1同时打开之后，Rx_1打不开。

老师好：

       我在将FFTC_0和FFTC_1同时打开之后，并且配置好Rx后，Rx_0可以打开，但是Rx_1打不开，请老师帮我看一下是哪一块错了，非常感谢！

程序如下:

// Fftc_open 程序

     * of insertion, for now let's assume we got Mem region

    /* Setup the descriptors required by this app and
     * open the driver.
     */

    hFFTC_0 = Fftc_open (fftcInstNum_0, &fftcInitCfg, &retVal);
