使用usb_cdc_4g_module会死机 (AEGHB-395) #295

Szeroy · 2023-09-19T06:54:06Z

IDF版本是5.1，使用usb_cdc_4g_module的例程去连接4g模块会死机，用的是合宙air780e这款。
我例程里面的代码写在自己的任务里面：

//! Modem itf: IN Addr:0x84, OUT Addr:0x02
void air780_task(void *arg)
{
    uint16_t retry = 0, time_out = 0;
    uint32_t get_type = 0;
    /* Initialize modem board. Dial-up internet */
    modem_config_t modem_config = MODEM_DEFAULT_CONFIG();
    /* Modem init flag, used to control init process */
#ifndef CONFIG_EXAMPLE_ENTER_PPP_DURING_INIT
    /* if Not enter ppp, modem will enter command mode after init */
    modem_config.flags |= MODEM_FLAGS_INIT_NOT_ENTER_PPP;
    /* if Not waiting for modem ready, just return after modem init */
    modem_config.flags |= MODEM_FLAGS_INIT_NOT_BLOCK;
#endif
    modem_board_init(&modem_config);
    vTaskDelay(15000 / portTICK_PERIOD_MS);

    esp_err_t err = ESP_FAIL;
    while (err == ESP_FAIL)
    {
        err = esp_modem_dce_generic_command(s_dce, "AT+CGNSPWR=1\r", MODEM_COMMAND_TIMEOUT_DEFAULT, esp_modem_open_gps, NULL);
    }
    err = ESP_FAIL;
    if (get_user_config()->imei[0] != 0)
    {
        ESP_LOGI(TAG, "imei = %s\n", get_user_config()->imei);
    }
    else
    {
        while (err == ESP_FAIL)
        {
            err = esp_modem_dce_generic_command(s_dce, "AT+CGSN\r", MODEM_COMMAND_TIMEOUT_DEFAULT, esp_modem_get_imei, NULL);
            vTaskDelay(2000 / portTICK_PERIOD_MS);
        }
    }

    int ber = 0;
    modem_board_get_signal_quality(&get_equipment_data()->rssi, &ber);
    while (1)
    {
        if (get_equipment_data_queue != NULL)
        {
            // gps_data_update = 1;
            xQueueReceive(get_equipment_data_queue, &get_type, portMAX_DELAY);
            if (get_type == GET_GPS_DATA)
            {
                modem_board_ppp_auto_connect(false);
                while (modem_board_ppp_stop(10000) != ESP_OK)
                {
                    vTaskDelay(1000 / portTICK_PERIOD_MS);
                }
                modem_board_get_signal_quality(&get_equipment_data()->rssi, &ber);
                vTaskDelay(200 / portTICK_PERIOD_MS);
                esp_err_t err = esp_modem_dce_generic_command(s_dce, "AT+CGNSINF\r", MODEM_COMMAND_TIMEOUT_DEFAULT, esp_modem_dce_handle_get_gps_data, NULL);
                if (err != ESP_OK)
                {
                    retry++;
                    if (retry == 20)
                    {
                        modem_board_force_reset();
                        ESP_LOGE(TAG, "get gps data failed,modem reset");
                        break;
                    }
                    else
                    {
                        ESP_LOGW(TAG, "get gps data failed,retry = %d", retry);
                    }
                    vTaskDelay(1000 / portTICK_PERIOD_MS);
                }
                if ((get_equipment_data()->latitude != 0) && (get_equipment_data()->longitude != 0))
                {
                    gps_data_update = 1;
                }
            }
        }

        if (get_type == START_PPP)
        {
            modem_board_ppp_auto_connect(true);
            modem_board_ppp_start(500);
        }
    }
}

但是执行到这两步的时候会死机：

 case STAGE_CHECK_SIGNAL:
    if (_check_signal_quality() != true)
    {
        retry_after_ms = 3000;
        ++stage_retry_times;
    }
    else
    {
        modem_stage = STAGE_CHECK_REGIST;
        goto _stage_succeed;
    }
    break;
case STAGE_CHECK_REGIST:
    if (_check_network_registration() != true)
    {
        retry_after_ms = 3000;
        ++stage_retry_times;
    }
    else
    {
        modem_stage = STAGE_START_PPP;
        goto _stage_succeed;
    }
    break;

有时候加上printf或者把esp_modem_process_command_done挪到字符串解析之后，就不会死机了，这个是原来的代码，没有改

static esp_err_t esp_modem_dce_common_handle_csq(esp_modem_dce_t *dce, const char *line)
{
    esp_err_t err = ESP_FAIL;
    if (strstr(line, MODEM_RESULT_CODE_SUCCESS)) {
        err = esp_modem_process_command_done(dce, ESP_MODEM_STATE_SUCCESS);
    } else if (strstr(line, MODEM_RESULT_CODE_ERROR)) {
        err = esp_modem_process_command_done(dce, ESP_MODEM_STATE_FAIL);
    }
    if (strstr(line, "+CSQ")) {
        /* store value of rssi and ber */
        esp_modem_dce_csq_ctx_t *csq = dce->handle_line_ctx;
        /* +CSQ: <rssi>,<ber> */
        sscanf(strstr(line, "+CSQ"), "%*s%d,%d", &csq->rssi, &csq->ber);
        err = ESP_OK;
    }
    return err;
}

有没有可能存在任务优先级的问题，在这里面看到任务优先级加3，但是好像没看到哪里调用了CONFIG_USBH_TASK_BASE_PRIORITY 这个宏定义：

#define MODEM_DEFAULT_CONFIG()\
    {                                \
        .rx_buffer_size = 1024*15,   \
        .tx_buffer_size = 1024*15,   \
        .line_buffer_size = 1600,    \
        .event_task_priority = CONFIG_USBH_TASK_BASE_PRIORITY + 3,\
        .event_task_stack_size = 3072\
    }

只使用例程下进去是正常的，但是用在项目中会不会跟多创建了几个任务有关系。

基本上只在查询信号和运营商的时候会死机，如果直接注释掉这两个步骤，就过去了

请问有找到这个问题吗

leeebo · 2023-09-27T02:54:15Z

LoadProhibited EXCVADDR: 0x00000014 意思是内存加载错误，地址是 0x14。大概率是在读一个结构体空指针，触发异常。

example 代码你有更改吗？

example 代码你有更改吗？

之前example是可以的，example初始化是在main里面的，现在我是把初始化新建了个单独任务，这个会不会存在问题。
现在比较怀疑的是，有没有可能存在发送at指令，没有等收到就直接去解析，类似于事件和任务的优先级问题。
目前把这个库里面_modem_daemon_task的优先级再往上加一点就不会死机了，现在不太确定具体是不是这个导致的。

好的，因为有问题改库稍微有点麻烦
