MT2523 I2S的slave模式，调用hal_i2s_enable_tx()会死机

    MT2523 I2S的GPIO4 gpio5 gpio6 gpio7只能做i2s的salve模式，外接codec，设置pinmux之后，调用i2s_open（）函数，运行到hal_i2s_enable_tx（）的时候会死机，
i2s_open（）函数如下：

static int32_t i2s_open(void)
{
uint32_t memory_size = 0;
uint8_t *memory;
hal_i2s_config_t i2s_config;
hal_i2s_status_t result = HAL_I2S_STATUS_OK;

LOG_I(WM8904,"ENTER\r\n");i2s_config.clock_mode = HAL_I2S_SLAVE;// configure the RX settingsi2s_config.i2s_in.sample_rate = HAL_I2S_SAMPLE_RATE_8K;i2s_config.i2s_in.channel_number = HAL_I2S_MONO;// configure the TX settingsi2s_config.i2s_out.sample_rate = HAL_I2S_SAMPLE_RATE_8K;i2s_config.i2s_out.channel_number = HAL_I2S_MONO;// set the I2S to an external mode.result = hal_i2s_init(HAL_I2S_TYPE_EXTERNAL_MODE);if(HAL_I2S_STATUS_OK ！= result) {

重新发一下i2s_open（）函数

1. static int32_t i2s_open(void)
   
2. 
   
3. {
   
4.         uint32_t memory_size = 0;
   
5.         uint8_t  *memory;
   
6.         hal_i2s_config_t i2s_config;
   
7.         hal_i2s_status_t result = HAL_I2S_STATUS_OK;
   
8. 
   
9.     LOG_I(WM8904,"ENTER\r\n");
   
10.         i2s_config.clock_mode = HAL_I2S_SLAVE;
    
11.         // configure the RX settings
    
12.         i2s_config.i2s_in.sample_rate = HAL_I2S_SAMPLE_RATE_8K;
    
13.         i2s_config.i2s_in.channel_number = HAL_I2S_MONO;
    
14. 
    
15.         // configure the TX settings
    
16.         i2s_config.i2s_out.sample_rate = HAL_I2S_SAMPLE_RATE_8K;
    
17.         i2s_config.i2s_out.channel_number = HAL_I2S_MONO;
    
18. 
    
19.         // set the I2S to an external mode.
    
20.         result = hal_i2s_init(HAL_I2S_TYPE_EXTERNAL_MODE);
    
21.         if(HAL_I2S_STATUS_OK ！= result)
    
22.         {       
    
23.                 LOG_E(freertos,"error result = %d \r\n",result);        
    
24.         return -1;
    
25.         }
    
26. 
    
27.         result = hal_i2s_set_config(&i2s_config);
    
28.         if(HAL_I2S_STATUS_OK ！= result)
    
29.         {
    
30.                 LOG_E(freertos,"error result = %d \r\n",result);        
    
31.         return -2;
    
32.         }
    
33.        
    
34.     // get the amount of internal-use memory   
    
35.     hal_i2s_get_memory_size(&memory_size);   
    
36.         memory = malloc(memory_size * sizeof(uint8_t));   
    
37.         if(NULL == memory)
    
38.         {      
    
39.                 LOG_E(freertos,"error result = %d \r\n",result);
    
40.         }   
    
41.        
    
42.         result = hal_i2s_set_memory(memory);   
    
43.         if(HAL_I2S_STATUS_OK ！= result)
    
44.         {      
    
45.                 LOG_E(freertos,"error result = %d \r\n",result);  
    
46.         }
    
47. 
    
48.     LOG_I(WM8904,"pass\r\n");
    
49. 
    
50.     hal_i2s_register_tx_callback(user_i2s_tx_callback, NULL);   
    
51.         hal_i2s_register_rx_callback(user_i2s_rx_callback, NULL);
    
52. 
    
53.     LOG_I(WM8904,"pass\r\n");
    
54. 
    
55.         result = hal_i2s_enable_tx();
    
56.         if(HAL_I2S_STATUS_OK ！= result)
    
57.         {
    
58.                 LOG_E(freertos,"there is an  error \r\n");
    
59.         return result;
    
60.         }
    
61.        
    
62.         result = hal_i2s_enable_rx();       
    
63.         if(HAL_I2S_STATUS_OK ！= result)

66.         return result;
    
67.         }
    
68. 
    
69.     LOG_I(WM8904,"EXIT\r\n");
    
70. 
    
71.     return 1;
    
72. }

会不会可能 指针方面引起的错误?

不是，现在已经不死机了，就是要 调用一下这个 hal_audio_init()初始化，还是不明所以，并且我现在user_i2s_rx_callback接收到的数据一直有问题
